 rosis, gradatim crescentibus, prope suturam elevatis ; varicibus 

 numerosissimis, laminatis, crenulatis, superne angulatis ; aperturd

 A small elongated turreted shell, to the beauty "of which neither 

 the description nor the figure can do justice: the varices are nume- 

 rous, laminated, and regularly crenulated.

 sand at thirty fathoms ; and at the isle of Corregidor, in sandy mud 

 at thirty fathoms.

 varicibus numerosis, regularibus, oblique in spiram continuis, sub- 

 rotundatis ; aperturd ovali, labio interne tenui ; colore pallidissime 

 fulvo. 

 The whorls in this species are more prominent, the ribs more nu-
