Differs from elaboratum by having two sub-equ-al umbilical 

 ribs, by having its periphery well rounded or obtuse, by its more 

 depressed form. The diagonally elongated crenulations on the 

 striae resemble closel}^ those on elaboratum , though there is more 

 similarity in the strength of the lines and markings above than 

 there is in typical elaborahun.

Dair s description is as follows: "The umbilical carina is annu- 

 late with nineteen strong, transversely-ruled tubercles, separated 

 from the strong similar umbilical rib by an excavated sulcus; the 

 rib is prominent, and looks, to a casual inspecSlion, as if it were 

 the top of the umbilical wall of the vi'horl, which is not the ca.se; 

 the shell is depressed, with a wide, thin carina, blunt and slightly 

 undulate on the edge; both the under and upper surfaces of the 

 whorls are concave; the keel overhangs the suture in front; the 

 base outside of the umbilical carina is smooth, with a single fine 

 thread in the bottom of the excavation; on the summit, above 

 the keel, are four fine beaded or undulated spirals, separated by 

 much wider interspaces, those next the suture stronger than the 

 other two. Alt. 5.5; diam. ii.omm.; the apical whorls are es- 

 timated for, being defedlive in the type." Wautubbee, Miss. 



The markings on the specimen herewith figured are a little 

 more pronounced than Ball's description would indicate. Below 

 towards the exterior there are several fine spiral lines.
