Hab Kobis (£. L. Layard). 
This seems to us to differ from B. Burchelli (Gray) in the 
smaller size, want of umbilication, greater reflexion of colu- 
mella, less ventricose whorls, and more vivid painting. Mr. 
Layard remarks that one of his three specimens shows a rather 
solid epiphragm 7n s¢tu, which would seem to indicate estiva- 
tion at one period of the year.

basin marginis columellaris reflexo.
