“This species is somewhat allied to D. puppensis, Blf., differing 
from it by its constant smaller size, more tumid or convex and more 
widely costulated whorls, and by the aperture being at the columellar 
base rounded or nearly so,instead of decply angular and canaliculate as 
it always appears to be in puppensis. The present species was found 
to be very common on the perpendicular limestone cliffs at Damotha, 
especially in localities where a little water trickled down the rock. 
The animals seemed to feed on minute algw which were growing in 
the locality.”

genus Palaina of Semper (vide Journ, de Conch. 1863, p. 291, and 
1866, p. 348), although, if the subgenus should be retained, it can- 
not include all the species referred to it by its author.”
