Specific Cliaracters. — Shell tliick and solid, ovate ; wliorls G, slightly convex, 

 the last ventricose, two-thirds the total length; spire regularly conical, with a 

 minute rounded apex ; ornamented by numerous longitudinal costae and by spiral 

 ridges nearly equal in size, which become more or less tuberculate where they 

 intersect; suture channelled, but not deep; mouth rather sliort, ovate-angulate 

 above ; outer lip thickened, ridged internally ; inner lip strong ; peristome con- 

 tinuous. 



Dimensions. — L. 5 mm. B. 3 mm. 



Distribution. — Recent : Isle of Jura, Cumbrae (Jeffreys). Mediterranean (widely 

 distributed), Adriatic, ^gean, Crete, Lycia. West Atlantic (Carus). 

 Fossil : Selsey. 



Upper Pliocene : Monte Mario, Astiano, Val d'Era, Altavilla. 



Pleistocene : Messina, Monte Pellegrino, Ficarazzi, Sciacca, Reggio, Taranto, 

 Gravina, Livorno. Sub-Btnean beds : Salustri, Cibali, Catira, Nizzeti, San 

 Paulo. 



Bemarks. — This very distinct and southern sliell has been reported by Mr. Bell 

 as a British fossil from Selsey only, where he informs me that years ago it was 

 fairly common. In the south of Europe it occurs in the Upper Pleistocene of Asti, 

 Monte Mario and Altavilla, while Seguenza gives it from a number of Italian and 

 Sicilian localies and Dr. Scalia from the fossiliferous deposits on the flanks of 

 Etna.
