Description.— InitvmX casts of median size, subovate in form, 

 the diminsions of a nearly complete one being : height, 35 mm. ; 

 greatest diameter, 20 mm. ; height of aperture, about 22 mm. ; 

 width of aperture, 7.5 mm. Volutions about four in number, the 

 suture well defined, the height of the spire less than one-half 

 the total height of the shell. Volutions of the spire gently con- 

 vex and nearly vertical for two-thirds of this height from the 

 suture below, curving much more strongly above to the upper 

 suture. Surface of the cast without well-defined markings. 



Remarks. — This species is represented in the New Jersey col- 

 lections only by internal casts, which in no case preserve the 

 form of the expanded and thickened outer lip. It is not possible 

 tO' identify these casts with absolute certainty, but on comparison 

 with authentic specimens of the species in the National Museum 

 at Washington, the New Jersey examples seem to belong here. 



Formation and locality. — Wenonah sand, near Crawfords 

 Corner (126^). 



Geographic distribution. — New Jersey, Mississippi.
