MOLLUSCA OF INDIA. 129 
There are two specimens, unfortunately neither of them fully grown, 
in Mr. W.'T. Blanford’s collection. No. 36 of his MS. list unnamed, 
and with a note “ not WV. blanfordi.” Compared with this last, I note 
that blanfordi has a more contracted umbilicus, and the sculpture 
is quite different. Compared with ovytes it is closer wound, not so 
flat above, and must, when fully grown, have a greater number of 
whorls; the umbilicus is not so open and the region round it very 
differently formed. 
This appears to be the species from the Shan States which Mr. 
Theobald, in his Supp. Catalogue to the ‘Conchologia Indica,’ identifies 
as the same as the Darjiling form blanfordi mentioned above. There 
is no doubt regarding its distinctness. 
A figure of this species will be given hereafter.

The animal of this species (Plate XXX. fig. 4) was also figured by 
me in the ‘Journal of the Asiatic Society of Bengal,’ from the drawing 
made under Ferd. Stoliczka’s superintendence. I have since obtained 
a Specimen in spirit from Mr. Blanford, which has enabled me to 
give a few notes on its anatomy ; and Mr. W. Robert’s recent collec- 
tions in the Bhutan Hills have given me several more. Although on the 
general plan of structure of this family, there are some well-marked 
differences and peculiarities. 
The animal (Plate XXXII.) has no right shell-lobe to the mantle ; 
the right dorsal lobe (fig. 1 a) is well developed, as is also the anterior 
portion of the left, although it does not extend very far on the left 
margin of the peristome ; for its posterior portion, lying some distance 
on the basal side, is small and apparently bilobed (figs. 1 and 1 4). 
The shell-lobe is slightly reflected over the margin of the peristome 
from the respiratory orifice. The mucous pore at the extremity of 
the foot is linear, and no horn is developed, though it is represented 
by a short blunt process (vide Plate XXXII. fig 1 ¢). 
The ovo-testis is very large, the follicles extremely minute, and it 
might be taken for a portion of the liver, only that its colour is of a 
darker brown. The hermaphrodite duct (fig. 5, 4.d.) is exceedingly 
long,and much convoluted for its entire length; near the end it divides 
into two still convolute ducts which lead into the mass of the ovo- 
testis: it is thus unlike this portion of the generative organs in all 
other species I have as yet examined, and may indicate the develop-
