I have half a dozen well-prcsen'ed specimens, which present characters sufficient 

 to justify this being considered identical wdth 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. li^). Two of my specimens have five or six of the upper volutions broken oS', 

 and the opening closed in a manner similar to that of Bulmus decoUatus.

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. 



Axis, I of an inch. 



Locality. Cor. Crag, Sutton and Ramsholt. Recent, British Seas. 



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 proba- 

 bility, only young individuals. My specimens do not possess more than eight volutions ; 

 recent indi\'iduals of the same length have about an equal number. The apex in this 

 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.
