14. Pypula altispira, sp. nov. Plate III., figs. 2 and 3. 



►Shell pyrifonn, very thin, with a well-elevated obtuse spire, 

 consisting of an embryonic portion of about three smooth, regu- 

 larly convex, gradually increasing whorls, succeeded by four 

 rapidly increasing ventricose whorls. 



Apical angle about one hundred degrees. Earlier spire-whorls 

 convex, penultimate slightly shouldered, body-whorl distinctly 

 shouldered. In the neighbourhood of the aperture that part of 

 the shell between the suture and the shoulder is almost perfectly 

 flat, though gently sloping down to the shoulder, which is at a 

 somewhat lower level than the suture ; posteriorly this portion 

 becomes gradually more and more convex, ultimately losing 

 entirely the appearance it possesses near the aperture. Greatest 

 width of body-whorl a little below the shoulder, thence gradually 

 contracted to the somewhat long and arched canal. Aperture 

 elongate and iia)-rowly oval ; outer lip simple and sharp, at the 

 posterior end straight from the suture to the convexly rounded 

 shoulder, thence gradually and regularly convexly arched to the 

 anterior end of the canal. Columella simple, faintly enamelled, 

 slightly arched to the right, then to the left. Canal long, rather 

 wide, and slightly bent to the left. Surface ornamented with 

 fine, regular, flatly rounded spiral threads, about ten in number 

 in the space between the suture and the shoulder of the body- 

 whorl, and about ten or twelve on the spire-whorls. On the 

 body-whorl, at about its greatest breadth, the spiral threads are 

 coarsest and reach nearly half a millimetre in thickness, thence 

 anteriorly and posteriorly becoming much finer, ultimately very 

 fine at the anterior end of the shell and just discernible on 

 the pcisterior spire-whorl. Interspaces between the spiral threads 

 about twice the width of the threads, flat and shallow. Both 

 interspaces and spiral threads finely spirally striate, most notice-
