Shell description.
The matt, opaque, solid shell grows sublittorally to 50 mm high and 25 mm wide (Fretter & Graham, 1985) fig. 01 flic.kr/p/2op3qCC, but most intertidal specimens are less than 30 mm high fig. 02 flic.kr/p/2op6v13 . The body-whorl is about 75% of the shell’s height. Those in the Mediterranean are larger (Jeffreys, 1867), occasionally up to 65 mm high (Pers. comm. Jakov Prkić, 18 March 2023), are generally more colourful and ornate fig. 03 flic.kr/p/2op3Kef & fig. 04 flic.kr/p/2op6tN8 and there are some differences in body features. The differences may be geographical variation, but it would be helpful if differing specimens could be molecularly sequenced.
Each of the tumid whorls has an angled shoulder and eight or nine widely spaced, strong costal ribs which are crossed by two major, rounded spiral cords on the spire whorls and by eight or nine on the body-whorl fig. 05 flic.kr/p/2op6th8 ; minor cords are also present. There are low knobs where the cords and costal ribs intersect. Numerous flounced growth lines cross the spiral cords and grooves and give the whole shell an imbricate appearance fig. 06 flic.kr/p/2op6t35 & fig. 07 flic.kr/p/2op8Aq1 unless eroded, when they survive longest in the grooves fig. 01 flic.kr/p/2op3qCC . On adults the most recently formed costal rib acts as a labial varix which thickens the palatal lip of the aperture fig. 05 flic.kr/p/2op6th8 unless there has been recent new growth fig. 06 flic.kr/p/2op6t35 . The sutures between the whorls are deep and sinuous. The sculpture becomes more pronounced with age. The shell exterior is yellowish white fig. 05 flic.kr/p/2op6th8 with varying amounts of brown which may create bands associated with the spiral cords or costal ribs fig. 08 flic.kr/p/2op6sCH . The protoconch, lacking obvious sculpture, has about two and a half tumid, smooth whorls about 1 mm in diameter fig. 02 flic.kr/p/2op6v13 which, when not eroded, form a sharp apical point.
The height of the aperture is about 60% of the shell height fig. 02 flic.kr/p/2op6v13 . It is approximately ‘P’ shaped with the nearly straight inner lip (parietal and columellar) and long siphonal canal forming the upright, and the palatal lip forming the curve. On young shells the canal is open fig. 02 flic.kr/p/2op6v13 . Later the columellar lip expands over the canal to roof it fig. 08 flic.kr/p/2op6sCH to a greater or lesser degree. All lips are pure white and the parietal lip tends to spread onto the adjacent body-whorl. The palatal lip may consist of the labial varix or a thin, finely folded lip projecting a minimal fig. 05 flic.kr/p/2op6th8 or moderate fig. 06 flic.kr/p/2op6t35 distance beyond the varix, depending on recent growth and erosion. It meets the parietal lip at about 90°. On mature shells, the palatal lip often has interior protrusions which correlate with the spiral grooves of the exterior fig. 09 flic.kr/p/2op8Yue . The interior of the aperture is smooth and glossy white.
The operculum fig. 10 flic.kr/p/2op7LKL has a fairly straight columellar-parietal edge. Its palatal edge is curved except for a straight basal section which, with the columellar-parietal edge, forms a wedge which fits into the siphonal canal. Centrally, it is dark reddish brown, but a wide peripheral zone is translucent yellowish fig. 11 flic.kr/p/2op6rLh .The outer face, made of conchiolin produced by the opercular groove, has a marginal nucleus with many fine, surrounding, concentric growth lines. The inner face has a non-marginal, excentric nucleus surrounded by broad, concentric, bands of adventitious conchiolin produced by a ring of gland cells in the opercular disc fig. 10 flic.kr/p/2op7LKL . Both interior bands and exterior growth lines are visible through the translucent operculum when viewed against a backlit white background; the patterns cross each other fig. 11 flic.kr/p/2op6rLh . The inner face has an area of rougher texture where the columellar muscle attaches to it. The edge of the attachment area is visible as a curved line unaligned with either growth lines or adventitious bands. Apart from the rough muscle-attachment, the inner face of operculum has a shiny varnished surface fig. 10 flic.kr/p/2op7LKL . The operculum is flexible so it can fit the aperture tightly behind the interior protrusions, if any, of the palatal lip fig. 09 flic.kr/p/2op8Yue or bend round the body fig. 12 flic.kr/p/2op8XAa .
Body description
The flesh is translucent white or yellowish white with many opaque white blotches, and yellow, sometimes saffron (Jeffreys, 1867), distally on the cephalic tentacles fig. 12 flic.kr/p/2op8XAa & fig. 13 flic.kr/p/2op8XsQ , but the yellow may not be developed on small juveniles fig. 07 flic.kr/p/2op8Aq1 and juveniles less than 5 mm high in the Adriatic may have grey and black bodies fig. 37 flic.kr/p/2opNWxW . Dark viscera are visible in parts of the body rarely extended into view fig. 14 flic.kr/p/2op7KP7 .
The small dorsoventrally flattened head consists of two diverging cephalic tentacles with thick bases tapering about two thirds of their length to an eye fig. 12 flic.kr/p/2op8XAa & fig. 14 flic.kr/p/2op7KP7 beyond which they are slender. Ventrally there is an opening slit (rhynchostome) fig. 15 flic.kr/p/2op8WGX for eversion of the pleurembolic feeding proboscis which can extend greatly; there is no permanently external snout. The radula, buccal mass and true mouth are in the distal end of the proboscis fig. 14 flic.kr/p/2op7KP7 when extended. The short rachiglossan radula has in each row of three colourless, transparent teeth a wide, central, rachidian tooth with many small cusps (points) flanked on either side by a longer marginal tooth. The cusps on the anterior rows are usually worn down by boring into the shells of prey.
The translucent yellowish white mantle roofs the mantle cavity fig. 12 flic.kr/p/2op8XAa and a folded portion fig. 14 flic.kr/p/2op7KP7 extends as a respiratory siphon through, but rarely beyond, the siphonal canal of the shell fig. 17 flic.kr/p/2op6qtC . The mantle covers the body but is translucent enough to reveal the organs when the animal is removed from the shell fig. 22 flic.kr/p/2op8VfZ . The edge of the mantle is thickened, more yellowish and less translucent fig. 12 flic.kr/p/2op8XAa .
The short, broad foot is about 33% the length of the shell fig. 18 flic.kr/p/2op6qhA . When fully spread it is widest at the anterior fig. 19 flic.kr/p/2op7JJm but it can vary to circular fig. 20 flic.kr/p/2op3Ek2 . There are no distinct propodial tentacles, but the agile foot can fold readily and bring the sides and flexible front corners together fig. 17 flic.kr/p/2op6qtC to manipulate prey or, in the case of females, manoeuvre egg capsules. The opening to the inverted accessory boring organ is on the medial fold line of the sole a short distance from the anterior. It is difficult to detect except when the sucker-like boring organ is everted to hold and to soften the shell of the prey for boring by the radula. A little further posterior than the boring gland on females there is an opening to the ventral pedal gland into which the foot inserts each newly laid egg capsule for final shaping and subsequent fixing to the substrate.
Dorsally the foot is coloured as the body but the yellowish white sole lacks opaque white marks except where those on the dorsum show through the thin periphery fig. 20 flic.kr/p/2op3Ek2
Behind the right tentacle, males have a large, white penis fig. 21 flic.kr/p/2op6pqL .
Removal of the shell fig. 22 flic.kr/p/2op8VfZ & fig. 23 flic.kr/p/2op8wre will show a large, yellowish, pinnate ctenidium and a smaller, pinnate, red-brown osphradium resembling a ctenidium in structure. The following organs may be visible through the translucent mantle: the greenish hypobranchial gland, rectum, black rectal gland, heart, kidney and the visceral lump containing the digestive gland and, in the breeding season, the ovary or testes.

Similar species
Shells have intraspecific variations with interspecific overlap, and features may be eroded or indiscernible on images, so use of more than one feature is advisable for reliable identification.
Ocinebrellus inornatus (Récluz, 1851)
O. inornatus “is very similar to Ocenebra erinaceus and is very difficult to distinguish due to the morphological variability of both” (Trigo et al. 2018). First arrivals of this invasive species are frequently mistaken for O. erinaceus. Large unworn adult shells of O. inornatus show the most distinct sculptural features. The form of egg capsules and colour of tentacle tips are diagnostic in north-west Europe.
1. Maximum height 63 mm (fig. 27 flic.kr/p/2op7GK1 ).
2. Usually 8 to 9, occasionally 4 to 12 costal ribs (Amano & Vermeij 1998 in Goud et al. 2008) on body-whorl. They are more prominent and angulated at the shoulder giving a more pronounced turreted effect than on Ocenebra erinaceus fig. 25 flic.kr/p/2op8vQj . No imbricate growth lines are visible in images of O. inornatus available for this account fig. 26 flic.kr/p/2op7GSA .
3. On large mature specimens the ribs on the body-whorl may be blade-like with the final one flaring out widely from the lip, level with the substrate fig. 27 flic.kr/p/2op7GK1 . But the more frequent smaller specimens have costal ribs and a labial varix like those on O. erinaceus fig. 25 flic.kr/p/2op8vQj .
4. 4 to 7 spiral cords on the body-whorl (Lützen et al, 2011).
5. Shell white with varying amounts and shades of brown. Aperture lips and siphonal canal white are sometimes whitish and brownish in parts. Siphonal canal is often slightly shorter than aperture above it.
6.Cephalic tentacles distally pure white without any yellow beyond the eye fig. 26 flic.kr/p/2op7GSA & fig. 28 flic.kr/p/2op3CD1 but some may be white faintly tinted brownish or pinkish proximally below the eye fig. 29 flic.kr/p/2op7Grf .
7. Egg capsules 15 to 20 mm high. Shaped like a kite with rounded lateral corners and a face strongly flexed so its two wings bend towards each other. Its tall neck tapers to a narrow aperture. Initially whitish turning yellow with age fig. 24 flic.kr/p/2op6oKN .
8. China, Korea, Japan and Sakhalin Island. Preys on Magallana gigas and has been accidentally translocated with commercial shipments of M. gigas to Pacific coasts of North America and to Europe from Iberia to Denmark. Locally common and a pest on oyster beds Not yet recorded in Britain (pers. comm. S. Taylor, Marine Recorder of Conchological Soc. G.B. & Ireland,15 March 2023) but because of difficulty in differentiating it from Ocenebra erinaceus it might be present unrecognised.
Ocinebrina aciculata (Lamarck, 1822)
1. Usual maximum height 15 mm and width 10 mm.
2. Eight to ten broad costal ribs on body-whorl. Slightly imbricate growth lines raised at irregular intervals, but not as prominently as on Ocenebra erinaceus.

4. 18 to 20 spiral ridges on the body-whorl.
5. Shell dark brown fig. 30 flic.kr/p/2op8TJc , may show red of body within when well lit in water fig. 31https://flic.kr/p/2op7G27 . Dead worn shells are paler. Sigmoid, pearlescent white, parietal-columellar (inner) lip fig. 30 flic.kr/p/2op8TJc does not extend onto body-whorl. Siphonal canal open and orange-buff, when young, closed when older.
6. Cephalic tentacles and whole body intense red flecked with yellowish white spots fig. 31 flic.kr/p/2op7G27 . Tips of tentacles and siphon paler.
7. Egg capsules barrel shaped (Wigham & Graham, 2018).
8. Found often in proximity of Perforatus perforatus (Cirripedia) from the Mediterranean to Bretagne, Scilly Isles and south-west England.
Urosalpinx cinerea (Say, 1822). fig. 32 flic.kr/p/2op6ngR
1. Maximum height 40 mm, width 20 mm.
2. 10 to 12 low, sometimes inconspicuous, costal ribs on final whorl.
3. Thin, crenulate palatal (outer) lip thickens and develops internal ribs with age. No labial varix.
4. 16 to 18 spiral ridges on the body-whorl, eroded where they cross the costae, so no protruding nodules. Sometimes spiral ridges more prominent than costae.
5. Shell yellowish or grey with brownish white aperture lips and siphonal canal. Open siphonal canal half the length of the aperture above it.
6. Flesh is cream with dark marks on tentacles and mantle edge.

3. No labial varix. Lip thin when young, thickened when full grown.
4. Shell often worn smooth fig. 34 flic.kr/p/2op3AEX but some have about 2 spiral bands on the spire whorls and about 10 on the body-whorl fig. 35 flic.kr/p/2op6kjQ .
5. Shell usually whitish; sometimes yellowish, and bands of various colours may occur fig. 34 flic.kr/p/2op3AEX . Aperture lips and siphonal canal usually white but can have patches of other colour.
6. Body and cephalic tentacles pure white fig. 34 flic.kr/p/2op3AEX .
7. Egg capsules are spindle shaped, up to 10 mm high and 4 mm wide, on a short thin stalk. Yellowish white becoming yellow or sometimes purple or brownish with age fig. 24 flic.kr/p/2op6oKN .
8. White Sea to Gibraltar, not Baltic (low salinity), and Greenland to New York. Common on hard substrate all around Ireland and Britain, avoiding low salinity of inner estuaries.
Habits and ecology
O. erinaceus lives on rocky shores at LWST and sublittorally to 150 m on stony substrate.
It feeds on bivalves, barnacles and tube dwelling worms, boring holes through their shells to rasp out the flesh with its radula. It takes about ten days to bore into and consume an oyster with its everted proboscis fig. 16 flic.kr/p/2op8y3A .
The strong shell affords protection against predators. When active, little of the animal protrudes beyond its shelter fig. 18 flic.kr/p/2op6qhA and the operculum protects nearly half of the foot. In Croatia those in shallow water are often covered with algae which conceal them fig. 36 flic.kr/p/2op3zyP . When sealed, the long siphonal canal protects the siphon so it can remain safely extended for respiration when the animal is retracted into the shell fig. 09 flic.kr/p/2op8Yue .
Inhalant water entering through the respiratory siphon has its quality checked by the pectinate osphradium at the inner end of the siphon before passing through the larger pectinate ctenidium fig. 22 flic.kr/p/2op8VfZ & fig. 23 flic.kr/p/2op8wre .
O. erinaceus breeds in late April and May in Britain. The male fertilizes the female internally with its long penis. Egg capsules from the oviduct are manoeuvred one at a time by the female’s flexible foot into the ventral pedal gland where they are moulded before being fixed to rock or shells. Several capsules are laid close together, and females often lay in company. The egg capsules are 6 to 13 mm high, and are shaped like a hot water bottle with sloping shoulders. Sometimes a raised rib creates a triangular cross section. The narrow aperture is on a short neck and has a protruding plug. The capsules are initially whitish turning to yellow or purple with age fig. 24 flic.kr/p/2op6oKN . After nine or ten weeks, most of the young emerge from the capsule as crawling juveniles, but about 14% emerge as late veliger, swimming larvae with a well developed four-lobed velum and a foot. They lose the velum within five days (Wigham & Graham, 2018).
Like Nucella lapillus, females in the vicinity of boats treated with Tributyltin (TBT), an anti-fouling biocide, experience imposex, the malformation of the oviduct causing sterility. Near Plymouth and Falmouth docks, England, about 90% of female O. erinaceus were so affected in studies from 1991 to 1995 (Gibbs, 1996). Even so, the reproductive failure was less than that experienced by N. lapillus perhaps because of arrival of swimming late veligers, which N. lapillus lacks, from less affected areas.
Distribution and status
O. erinaceus occurs from the Azores and the Mediterranean to its winter-cold induced limits in northern France and south-east Scotland. It does not live in the Baltic or on continental coasts of the North Sea; multiple records of it at
waarneming.nl/species/20959/maps/?start_date=2000-08-29&a...
are fossils in sand dumped to replenish Dutch beaches (Han Raven, pers. comm. 14 March 2023) and probably some misidentified Ocinebrellus inornatus. These misleading records have transferred to GBIF at www.gbif.org/species/4364689 . Because of the mild Atlantic drift in winter, it extends up the west coast of Ireland and Britain to Orkney and Shetland. The U.K. distribution map at species.nbnatlas.org/species/NHMSYS0021055838 probably shows the true position (accessed March 2023), but there, too, fossils are present in pleistocene glacial drift (Forbes & Hanley, 1853) from which they may be washed out onto beaches.
In the past, the limits have shifted. During the exceptionally severe winters 1928 - 1929 and 1962 - 1963, the population along the British North Sea coast was almost annihilated (Lützen et al., 2011). With global warming it is possible that it may spread north of its current limits, but recording of any change should be based on live specimens as the solid shells persist for long periods after death.

The Great Western Steam Up was held on the grounds of the Nevada State Railroad Museum from July 1 – July 4, 2022, in celebration of the 150th anniversary of the Virginia & Truckee Railroad. Nine operating steam locomotives were featured with many more on display. The event was billed as the largest reunion of existing V&T locomotives in over 75 years.

Daily events included rides behind visiting narrow and standard-gauge steam locomotives, a daily pageant of steam locomotives, historical vehicle and equipment displays, local food trucks, live entertainment, and “lost art” demonstrations.
The featured locomotives were:
Glenbrook, narrow gauge 2-6-0 (Baldwin 1875) built for the Carson & Tahoe Lumber & Fluming Company and used at Glenbrook, Nevada, along with an identical twin, Tahoe (see NCNG 5, below). It last ran in the 1920s and was acquired by the Nevada County Narrow Gauge for parts. In the 1940s it was placed on exhibit at the Nevada State Museum in Carson City and beginning in 1981 was restored to service (completed in 2015). It has been returned to its 1875 appearance.
No. 1, Joe. Douglass, narrow gauge 0-4-2T (H. K. Porter 1882) built for the Dayton, Sutro & Carson Valley Railroad. It operated at a mine in Dayton, Nevada, and later helped build Lake Arrowhead dam in California. It was cosmetically restored to its present appearance in 1994 and is displayed at the Nevada State Railroad Museum. It is a wood burner, but not operational.
No. 1, narrow gauge 0-4-0T (Porter 1889) built for the Sacramento Brick Company. It was later acquired by Hal Wilmunder and operated on his private Antelope & Western Railroad near Roseville, California. The engine is now owned and cared for by the Wilmunder family, and can usually be seen at the NCNG Museum in Nevada City, Calif.
No. 1, standard gauge 2-truck Heisler (Heisler Locomotive Works 1916), built for Bluestone Mining & Smelting. It originally worked on a 2.5 mile line near Mason, Nevada, before being acquired by a quarry in California. This oil-fired locomotive is owned by Chris Baldo and sees frequent use at Roots of Motive Power in Willits, California.
No. 1, Lyon, standard gauge 2-6-0 (Gentry/Strasburg/Kloke) which is a partially completed replica of the first locomotive built for the Virginia & Truckee. The original was manufactured by the Union Iron Works of San Francisco in 1869. The full-scale working replica was donated to the Nevada State Railroad Museum by Stan Gentry, builder, and is being completed by the museum shop staff. It will burn wood as did the original.
No. 3, standard gauge 0-4-0T (Porter 1909) built for the Santa Cruz Portland Cement Company. Upon retirement it was used as a billboard for a chicken restaurant in Stockton, California. It was restored to service by Stathi Pappas beginning in 2006 and is currently located at the Placerville & Sacramento Valley Railroad in Folsom, California. Nicknamed “Chiggen,” it is oil-fired.
No. 4, Eureka, narrow gauge 4-4-0 (Baldwin 1875), built for the Eureka & Palisade Railroad. Retired in 1938, it was later featured in several Hollywood movies. This classic wood-fired locomotive was restored by Dan Markoff in the 1980s and is usually kept at his home in North Las Vegas, Nevada.
No. 5, Tahoe, narrow gauge 2-6-0 (Baldwin 1875) built for the Carson & Tahoe Lumber & Fluming Company and used in logging service. It was later sold to the Nevada County Narrow Gauge of Grass Valley, Calif., and was retired in 1942. It then appeared in numerous movies and TV shows for owner Universal Pictures. No. 5 is now part of the NCNG Museum in Nevada City, Calif., and was restored to service in May 2022. This oil-fired locomotive has been restored to its 1940s appearance.
No. 8, standard gauge 4-4-0 (Cooke Locomotive & Machine Works 1888) built for the Denver, Texas & Fort Worth Railroad, and later operated on the Dardanelle & Russellville in Arkansas. It was used in 1976 on the V&T tourist railroad at Virginia City. Oil fired, it last steamed in the early 2000s.

It spent over fifty years at Old Tucson Studios in Arizona before being acquired by the V&T tourist railroad of Virginia City, Nevada, in 2021. It is currently under restoration. Oil fired.
No. 12, Genoa, standard gauge 4-4-0 (Baldwin 1873) built for the Virginia & Truckee. It was a back-up locomotive to the Reno and was retired in 1908. For the past 40 years it’s been on indoor static display at the California State Railroad Museum in Sacramento. It last ran in 1979 and was never converted from burning wood to burning oil, like most V&T 4-4-0s were.
No. 18, narrow gauge 4-6-0 (Baldwin 1911), built for the Nevada-California-Oregon and last used by the Southern Pacific. Restored by Carson & Colorado Inc. in 2017 after being on display in an Independence, Calif., park since 1954. It is normally kept at the Eastern California Museum in Independence. Oil fired.

No. 21, J. W. Bowker, standard gauge 2-4-0 (Baldwin 1875) built for the Virginia & Truckee. Bowker served as a switch engine in Virginia City. It was later purchased by the Sierra Nevada Wood & Lumber Company. Wood-fueled but not currently operational, it has been exhibited at the California State Railroad since 1976. An oil burner, it is not currently operational.
No. 22, Inyo, standard gauge 4-4-0 (Baldwin 1875), built for the Virginia & Truckee Railroad. It served in passenger service and was nicknamed “Brass Betsy.” It was later sold to Paramount Pictures and appeared McLintock, Union Pacific, and The Great Locomotive Chase. Restored to operation in 1983 and currently housed at the Nevada State Railroad Museum. Wood fired.
No. 25, standard gauge 4-6-0 (Baldwin 1905) built for the Virginia & Truckee to handle both freight and passenger trains. It was the first new steam locomotive purchased by the V&T and replaced older 4-4-0s on the passenger run between Reno and Carson City. Oil fired, it was restored to operation in 1980 and sees frequent service at the Nevada State Railroad Museum.

Good news, my angiogram checked out okay. No angioplasty, no stent, no bypass! They said I really hadn't changed since the last one five years ago. My nurse said I was the only one who lucked out that had the procedure done today. I will return in 3 weeks for a stress test and have an appointment with my cardiologist the first week in March. Picture was taken by Suzy in Innovis Hospital in Fargo. Fantastic place! I will catch up on everyone tomorrow morning after I get a good night's rest.

Getting one snow goose in St. John's is uncommon and exciting.... let alone nine!
W.Gash & Son of Newark was notable for buying nine Daimler CVD6 double deckers (its first double deckers) in 1948/9, mainly for use on its services between Newark and Nottingham. "Newark to Nottingham Direct" via the A46 & A52 was the main service, with others serving villages off the A46 between Newark & Bingham.
These buses had long lives, most of them lasting into the 1970's. Four of them, however, including DD4 (KNN622) - seen here setting off from Nottingham for Newark on the main road service in July 1968 - received new Massey H33/28R bodies in 1958 (DD2-4) and 1962 (DD1) to replace their original Strachan bodies. The original bodies had suffered from the use of sub-standard materials in the period of early post war shortages.

A matched pair of AC44's pilot Q015 through "downtown" Standley on a mild fall evening. I always enjoy catching the single-digit units on CSX.
It's weird to see Q015 running with double stacks up front now. This just recently changed thanks to more advancement in whatever corridor project CSX has been working on.
