MOLLUSCA OF INDIA. 41 
SITaLA SRIMANI, n. sp. (Plate IX. fig. 7.) 
Locality. Munipur (.-A.). 
Shell subdepressly turbinate, closely umbilicated; sculpture, with 
four or five indistinct longitudinal ribs, with rather coarse oblique 
lines of growth; colour ochraceous brown; spire depressed, apex 
blunt ; suture well impressed ; whorls 5, sides convex; aperture 
widely lunate ; peristome rather thickened, columellar margin very 
oblique and scarcely reflected. 
Size: major diam. 3°9 mm., alt. axis 2:2 mm. 
= O-16inch, ,, 0-09 inch. 
This shell is at first sight very similar to S. tertiana, but its close 
umbilication and different spire distinguish it. 
I have named this species after and in remembrance of a Goorkha, 
Duffadar Sriman, who was in the Khasi-Hills Survey Party, and a 
most excellent trustworthy man, who, like so many others, fell a 
victim at last to the climate of that part of India. He became a 
most diligent collector ; and to him I owe the possession of a large 
number of shells in my collection, which he even continued to collect 
atter I had left the Survey Party. I have always noticed that the 
Goorkha, Lepcha, and Khasia made much more intelligent collectors 
than the people of the plains 9f India, that they took a far greater 
interest in the work, and poss“ many of them a great amount 
of knowledge of animals and plants and their specific differences, 
while they recognize the numerous species, particularly the birds, 
by name.

“Diam. major 5, minor 43, axis 4 mill. 
‘« Hab, ad Heneratgodde, Ceylon.” Mr. Benson says :—* Allied to 
the Himalayan H. fastigiata, Hutton, and to the Bengal H. barrack- 
porensis, Pfr., but well distinguished by its more depressed form 
and by the filiform line, which, in addition to the keel on the last 
whorl, runs along the central part of each of the upper whorls. Mr. 
Layard had not been able to procure a second specimen.” TI do not 
agree with Mr. Benson as to the alliance or, I would rather say,
