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

 espanded aperture, and its widely channelled or contabuluted spire. 

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

Very likę the lašt ; it differs, however, in colour, in being more 

 acuminated, and in its tubercles being less prominent 5 it is, more- 

 over, a thinner shell. 



Found in tvvelve fathoms vvater vvith a muddy bottom. — G. B. S.

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

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

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



Cancellaria goniostoma. Canc. testd oblongd, fuscd ; spird acu-

 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.
