 beginning]; of a tooth. The reflected peristome is 

 not pure white, but partakes of the shade of the

 well defined umbilicus, the distinct and clearly de- 

 fined whorls, and the rich color making it one of the 

 most attractive of our smaller snails. It comes from 

 Bland, New Mexico, at an elevation of 8,000 feet 

 above the level of the sea.

 tooth, with teeth on the lip also. Peristome pale 

 chestnut-colored, diameter 17 mm. It is found near
