'^ Shell conic, tuireted, tapering' to an acute apex, white, immaculate, 

 iiiipertorate; irhorls about eight, in contact; eostfe- reguhu-, simjjle, not 

 reflected, e(piidistant, moderately elevated; .spaces between, the eosfce, with 

 very numerous approximate, ecpiidistant, impressed lines; suture well 

 impressed; Imdy whorl with about sixteen costae." (Say's description of 

 recent shell.) 



A single small sj)ecimen of this species has been collected, which is 

 about two-thirds as large as the recent shells. So far as the characters are 

 preserved, it agrees well with recent specimens, but as the shell is denuded 

 of the surface layer over the entire surface the line spiral striae can not be 

 observed. The specimen contains four and a half volutions, having- lost 

 two or more at the apex, and in consequence of the loss of surface shows a 

 small umbilical o})ening. The volutions are very round and full, with the 

 sutures deep and strongly marked; aperture very nearly circular, being 

 barely longer than wide; body whorl with eighteen longitudinal ribs, wh'ch 

 are directed back\vard in crossing from above to the lower side, but the 

 external features of the ribs are not preserved. 



Formation and locaUty: In the gray micaceous marls of the Miocene at 

 Jericho, N. J. From the National Museum collection.
