Shell ovate, brownish-white ; back rather gibbous, ornamented 

 with numerous white brown-edged ovate or roundish tubercles 

 attached to the anastamosing white brown-edged rib-stria? ; the 

 dorsal line distinct, impressed ; extremities rather produced and 

 slightly recurved ; the base convex, brownish-white, with numerous 

 close white brown-edged ribs; aperture narrow, linear; teeth 

 close; columella plaited, front part concave. Axis 1, diameter 



± of an inch. 



This species is distinguished from the former by the more con- 

 vex back and more produced and slightly recurved extremities. 

 It is only in very fine specimens that the brown edge to the ribs 

 and tubercles can be distinguished ; in others the shell is all pale 

 yellowish-white.
