22 PLIOCENE MOLLUSCA. 



Specific Characters. — Shell oblong, thin and fragile, whorls 3 — 4, moderately 

 convex, compressed above, the last much the largest, three-fourths the total 

 length ; spire short and pointed ; suture moderately deep, very oblique ; mouth 

 large, oval, angulate above; outer lip slightly thickened, inflected above; pillar lip 

 sharp. 



Dimensions. — L. 16 mm. B. 7 mm. 



Bistrihution. — Recent : throughout the British Isles, becoming scarce towards 

 the north. Widely distributed in Europe from Finland to Sicily, from France to 

 the Caucasus ; reported in North Africa from Algiers to Egypt ; in Asia from 

 Palestine to Cashmere (J. W. Taylor).

Holland — Pliocene: Utrecht, Amsterdam. Pleistocene: Gorkum, Purmereud. 

 Germany — Lower Pleistocene: Mosbach. France — Upper Pleistocene: Vin- 

 cennes. Upper Holocene of Denmark and Sweden (Nordmann). Holocene of the 

 Sahara : El Goleah. 



BeiriarJcs. — Messrs. Kennard and B. B. Woodward identify the specimen figured 

 by Wood as S. ohlonga with S. elegit ns, although it can hardly be regarded as 

 typical of the latter. Wood's specimen, which came from Bulchamp, is in the 

 British Museum (Natural History); the one from Coltishall mentioned by the 

 authors named as in the Norwich Museum cannot now be found. 



Dr. Lorie has reported 8. elegans from the Pleistocene beds (Eemien) met with 

 in some deep borings in the Valle Gueldroise, as well as from the Pliocene deposits 

 (Amstelien) underlying Amsterdam and Utrecht.
