2i0 MR. G. n. sowERUY ON NEW SPECIES OF SHEHs. [Mar. 20, 



have little doubt it will prove a Gihhula. The base is unusually 

 convex and ventricose, the s])ire rather shortly conical, and the 

 upper angle coronated with rounded tubercles. The mouth is rather 

 wide, and the umbilicus narrow. The spiral ridges on the base are 

 rather close, and the upper ones distant. 



I have only seen a single dead specimen of this somewhat remark- 

 able shell, vvliich has been lent to me for description by j\Ir. J.
