 easily distinguished from it by the absence of any markings, 

 the stronger and more distant ribs, and the open umbihcus.

Dentition : 20—1 — 20 ; laterals, 6. Central tooth rect- 

 angular, not much longer than broad, reflesed portion tri- 

 cuspid, the central cusp "with the cutting-point reaching the

 the central tooth, bicuspid, the inner cutting-point long, 

 reaching beyond the base. Marginals much broader than 

 long, with four to five cutting-points, the last minute, denticu-
