This very pretty shell is very distinct from any species hitherto 

 described from Northern India. It is probably allied to some of 

 the Ceylon species which like it have a membranaceous base. I 

 have had the specimens for some years in my collection. They 

 were, I believe, obtained by Mr. W. S. Atkinson.

This is a very distinct species, very much resembling in foliage 

 J), scabrella, Eoxb., but the flowers are quite different.
