1917. Euthria cornea, Monterosato, Moll. viv. e quat. Tripoli, p. 22; Boll. Soc. Zool. Jtal. [3], vol. iv. 



Specific Characters. — Shell fusiform, strong and solid; whorls slightly convex; 

 ornamented by flattened, inconspicuous spiral ridges which are more strongly marked 

 towards the base of the shell, by fine and numerous lines of growth, and on the 

 topmost whorls by strong, rounded, granular nodules and sometimes b}^ a few fine 

 longitudinal costas ; spire conical, more or less elongate; suture well marked; 

 mouth oval, with an angular notch above; canal short, narrow, recurved ; outer 

 lip with a sharp edge, grooved within. 



Dimensions. — L. 40 mm. B. 18 mm. 



Distribution. — Recent: Mediterranean, widely and generally diffused, Adriatic, 

 ^Egean, Morea, Syria. 



Fossil : St. Erth. 



Miocene : Touraine, Italy. 



Lower Pliocene : Siena, Biot. 



Upper Pliocene: Colli Astesi, Bologna, Orciano, Val d'Era, Altavilla. 



Pleistocene : Sicily — Messina, Monte Pellegrino, Ficarazzi, Catania, Rocca. 

 Calabria — Reggio, Castroreale, Monteleone, Taranto, Grravina. Tripoli. Tuscany 

 — Livorno, Valle Biaia. 



Remarks. — This characteristic Mediterranean species, widespread both as 

 recent and fossil, is reported from the English Pliocene of St. Erth only, where, 

 however, it is not very common. 



Mr. Bell points out (op. cit., p. 139) that the shallow sub-sutural groove, 

 characteristic of the recent shell, is absent in the St. Erth fossils. Profs, de Stefani 

 and Pantinelli remark (op. cit.) that it is less prominent than usual in specimens 

 from the Pliocene deposits of Siena.
