MOLLUSCA OF INDIA. 29 
8 mm. in the greater diameter, and those from the Western Ghats 
appear rarely to attain more than 6 mm. in the same diameter. 
The spiral angle varies in the Bengal specimens from 65°-78°; on 
the average it is decidedly smaller than in atlegia, and may be 
taken at 74°.” 
The great difference in the proportion of diameter to height 
between the Western Ghats form and the two other localities, in 
the first the two measurements being equal, denotes a very consi- 
derable modification of form, which may constitute, if constant, a 
very good variety. 
In ‘Contributions to Indian Malacology,’? No. IL., by Messrs. 
Blanford, they say “ This shell is tolerably abundant on Banyan 
trees (Micus indica) in the Botanical Gardens, Calcutta. We have 
also met with it in Orissa.”

“ Diam. major 8, minor 7, axis 8 mill. 
“Habitat ad Phie Than, vallis Tenasserim, frequens. 
“Distinguished from the Cingalese H. hyphasma, Pfr., by its 
narrower conical form, sculpture, structure of columellar lip, &c.” 
Locality of specimen figured. Moulmain (Stoliczka). 
Sculpture. On the upper whorls there are six distinct spiral 
ridges, the lowest being close to the suture; finer and intermediate 
ridges come in below, until on the last whorl they are numerous 
and rather close together, crossed by oblique regular striz.
