I have half-a-dozen well-preserved specimens, which present characters sufficient 

 to justify this being considered identical with the recent British species. Montague 

 says, the volutions are quite flat ; but in my specimens they are slightly convex in 

 the recent as well as in the fossil shell, with a rather obtuse apex; outer lip not 

 quite straight, projecting a little at- the lower part, with sometimes an inflection in 

 the spire (vide fig. 1 b). Two of my specimens have five or six of the upper 

 volutions broken off, and the opening closed in a manner similar to that of Bulimus 

 decollatus.

Shell elongate, tapering, smooth, and glossy, with an acuminated apex ; whorls 

 flat, contiguous ; suture scarcely defined ; aperture elongato-ovate, acuminated at 

 the upper part ; outer lip straight ; inner lip slightly reflected.

Small and mutilated specimens are by no means rare, and the above dimensions 

 are those of my largest and most perfect ones. There is no character I can detect, 

 but that of size, in which it differs from the recent species, and mine are, in all 

 probability, only young individuals. My specimens do not possess more than 

 eight volutions ; recent individuals of the same length have about an equal number. 

 The apex in tins species is sharper than in the preceding one. A species very 

 much resembling this shell, from the London clay, at Barton, is in the cabinet of 

 Mr. Edwards. It is rather more cylindrical and is less in size, with a more visible 

 suture; his largest specimen does not exceed three eighths of an inch in its axis 

 and yet appears an adult shell. Although so close an approximation, I think it is 

 distinct, and that gentleman is of the same opinion.
