sculpture on the base, and the upper whorls are strongly spiralled. Ilingicula acuta, Phil., from the 

 Bed Sea, is smaller, with a less swollen body-whorl and more tumid base, the whorls of the spire are 

 less tumid and less exserted. Ilingicula someri, De Polin, from the Cape Verde Islands, which is like 

 in general aspect, is a much smaller, thicker, and more spiralled shell, with a less tumid body-whorl 

 and more regularly conical spire, the slope of the whorls being more flattened ; the apex, too, is much 

 finer. Ilingicula scmistriata, d'Orb., from Cuba, is shorter, broader, and less spiralled. Ilingicula 

 auricidata, Menard, which is perhaps as like as any, has not the contracted base, and its extreme tip 

 is 0-004 in. broad, while here the tip is 0-008 in., or twice as much. 



I have called this species pcracuta, because, though certainly not very sharp, it is much more so 

 than Ilingicula acuta, Phil.

1 Though Klein^belongs to the prc-Linnean period, it is but just that the genus he proposed should bear his 

 name, since he differentiated it better than did Linne, who admitted into it many foreign elements.
