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 description, 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 h is 

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

 istic example of the long lost frons of Limueus.
