Remarkable for its dull, calcareous, tuberculated surface, its wide 

 expanded aperture, and its widely channelled or contabulated spire. 



Dredged in seven fathoms water with a sandy muddy bottom.—

Very like the last; it differs, however, in colour, in being more 

 acuminated, and in its tubercles being less prominent ; it is, more- 

 over, a thinner shell. 



Found in twelve fathoms water with a muddy bottom. — G. B. S.

A single specimen of this interesting shell was dredged in sandy mud. 



It is the most elongated species hitherto seen by Mr. Sowerby, and 

 in appearance approaches to the Mitres. — G. B. S.

 Hab. ad littora Americae Centralis, (Conchagua, San Salvador.) 

 A very fine and interesting species, of which a single specimen alone 

 was brought up from a sandy bottom in eight fathoms water. 



It is an approximation to the shell named Delphinula trigonostoma 

 by Lamarck, which would be properly placed in the genus Cancellaria 

 next to this species. — G. B. S.
