Hah. — La Paz, Bolivia, 3,600 metres. 



A beautiful and interesting shell described from a single specimen. 

 The curious malleation of the surface is very peculiar, and unique,

Eal. — Ecuador (Buckley's Coll.). 



This and the following species vrere collected by the late

 never been described.

Sai. — Valley of the R. Cauca, Colombia. 



This shell has been lately received by me, and appears to be quite 

 distinct from any hitherto known, although it must occur plentifully 

 in the district whence it came, judging from the number of specimens 

 (mostly imperfect) which have come to hand.

Cycl. testa ampliter umbilicata, orbiculari-depressa, superne ustulato-
