An Asiatic shell; introduced as taken alive on ships' bottoms. 

 Montagu, who first indicated it as British by name, scarcely ap- 

 pears to have intended this species, since, in his descri2ytion, he omits 

 all mention of the characteristic granules of the exterior, and the 

 scabrous edges of the interior.

A West Indian shell ; introduced by Dr. Turton, as it had been 

 taken alive on the bottom of a foreign vessel. The specimen in his 

 cabinet is not the true crista-galli as he imagined, but a character- 

 istic example of the long lost frons of LinncBus.
