A very elegant, small species, of a white colour, with three rows of 

 squarish brown marks ; like that of Cane, nodulifera (Sowerby in* 

 Tankerville Catalogue, Appendix), the inner lip is spread over part of 

 the last volution, giving the full-grown shell somewhat of the appear- 

 ance of a Cassis. 



Dredged in a sandy muddy bottom in from seven to ten fathoms. —

 When young, this shell is prettily decussated with rather prominent 

 though very narrow ribs ; but with age it becomes nearly smooth, 

 with obsolete strice. 



Two young ones were brought from Puerto Portrero, and an aged 

 specimen was dredged in fifteen fathoms in the Gulf of Dulce. — G.B.S.

 Another of those interesting species which form as it were the 

 passage from the typical Cancellarice to the species which Lamarck 

 has placed among the Delphinulee under the name of Delph. trigo- 

 nostoma. 



Two specimens were found, one at Puerto Portrero, the other at 

 St. Elena.— G. B. S. ■
