downwards. round the base of the columellar 
plait. 
In addition to the above-mentioned distinctions, the form 
should be noticed, the contour being much straighter and 
the whorls far less ventricose in the smaller species, calopasa. 
It should also be remarked that the longitudinal lire are far 
more oblique around the upper than on the last two whorls.

An Hnnea with most remarkable peristomatal processes, 
allied to H. dedalea, described in this paper, and even more

plait very nearly closes up the aperture.
