 tice subdilatato, armato ; labro margine jimbriato.

A small, solid, neatly sculptured species, with a narrow umbilicus, 

 and the interstices between the strong transverse ridges very coarsely 

 striate. 



Subgenus Gottoina, A. Ad. 



Testa turbinoidea seu trochiformis, imperforata ; anfractibus 

 transversim liratis. Apertura avata ; labia simplici, arcuato. 



This form differs from Fossar in the absence of the peculiar deep 

 rimal fissure, and in the inner lip being arcuate instead of straight ; 

 f.om Canradia and Couthouyia in being solid and imperforate ; and 

 from Isapis in the inner lip not being furnished with a tooth.

 anfractibus 3-j, convexis, liris transversis validis cequalibus, 

 interstitiis longitudinaliter concinne striatis, ornatis; apertura 

 ovata ; labio subincrassato, arcuato ; labro margine cremdato.
