Description. — " Shell short, subfusiform or elliptical ; smooth ; desti- 

 tute of ribs or striae; spire conical, the volutions convex; aperture ellip- 

 tical, about half the length of the shell; columella thick; labium re- 

 flected.'^ Conrad, 1842. 



Whitfield named some young shells from the St. Mary's formation in 

 a deep well at Cape May, ''Buccinanops variabilis" describing the species 

 as follows : 



" Shell rather small, not exceeding five-eighths of an inch in total 

 length; the body of a somewhat subcylindrical form, sometimes wider 

 below than above, and sometimes the reverse ; spire short-obtuse, or sub- 

 turreted; volutions of the spire round scalariform, with deep distinct 

 sutures, the apical ones often quite pointed and attenuated, with a small, 

 rounded, mammillary nucleus; aperture from half to three-fourths as 

 long as the shell, according to the length of the spire, channeled at each 

 extremity and constricted just below the suture on the body whorl, leav- 

 ing the upper edge of the volution protruding fold-like, the lip expanding 

 again below; inner lip extending upon the inner volution, forming a
