260 PLIOCENE M0LLU8CA. 



think, to be considered specifically distinct. The longitudinal ribs are fewer in 

 the latter and more jn-oniinent, the upper part of the whorls being distinctly 

 keeled, whereas in the present shell they are rounded or but obscurely angulate ; 

 the spiral sculpture, moreover, is different. My Crag specimens agree perfectly 

 with Nyst's species, B. similis, of which I figure one for comparison from the 

 Brussels Museum, received from my friend, M. Rutot. I have no hesitation in 

 regarding them as identical. 



Dr. Tesch has sent me a fossil from the Scaldisien deposits met with in one of 

 the Dutch borings which is evidently the same. 



I have one or two specimens from Oakley in my collection, more slender than 

 the type with a rather longer canal, which approach that figured in 188] by 

 Nyst as P. sahidata {op. cit., p. 51, pi. iii, fig. 16). M. Rutot informed me some 

 time ago that the original could not be found. The latter seems closely allied to 

 B. slnnlis, and may possibly be a variety of that species.

Specific Characters. — Shell rather thin, subfusiform, turreted ; whorls 8, 

 convex, the last much the largest, two-thirds the total length ; ornamented by 

 narrow and acute longitudinal costge, about eighteen on the body-Avhorl, nearly 

 reaching the base of the shell, not so wide as the intervening spaces, and by a 

 distinct keel Avith a sloping ledge above it ; also by unequally spaced and fine 

 spiral lines, a few of them more prominent than the others, with others, almost 

 inconspicuous, between them; spire attenuate, rapidly diminishing; apex acute; 

 mouth long, narrow, acutely angulate above, continuous Avith the canal Avhich 

 turns slightly to the left ; outer lip not expanded, angulated by the keel ; labial 

 sinus shallow and inconspicuous.
