MOLLUSCA OF INDIA. 225 
GIRASIA PANKABARIENSIS, n. sp. (Plate LIX. figs. 1, 1a, 1, 
animal.) 
Pankabari, foot of Darjiling Hills (coll. P. Séoliczka). 
Animal with the right and left mantle-lobes united, the line of 
junction well seen, as in the Khasi-Hill typical form; the mantle 
appears to be slightly speckled. The shell is deeply sunk in a 
depression, the ridge of the foot behind being on a level with the 
shell. It is the first true Girasia I have seen from the Darjiling 
country. 
Shell has been removed and is in the Calcutta Museum. 
Generative organs immature.

Girasia cinereus, G.-A., J. A. S. B. 1876, p. 314, plate viii. 
fig. 2. 
The shell was not described when taken, and it has since been 
mislaid. The description of the animal, which is of more importance, 
is as follows :— 
Original description :—* Animal, when fully extended, long and 
narrow, colour dusky grey, mantle with a papillate surface slightly 
spotted, the spotting being coarser on the body and tail. Tentacles 
short and blunt, with the oral ones very close below them. 
“ Length 0:75, mantle 0'°40. 
*« Hab. On the Darpang river, foot of the Dafla Hills, under old 
logs in the forest.”

Helicarion (Austenia) magnificus, Nevill, J. A. S. B. 1881, p. 129,

Girasia magnifica, Godw.-Aust. P. Z. 8. 1880, p. 294, pl. xxiv. 
figs. 1 and 2 (animal). 
Helicarion ( Austenia) magnificus, Nevill, Hand-list, p. 16. 
Nevill’s paper, “ List of the Mollusca brought back by Dr. J. 
Anderson from Yunnan and Upper Burmah,” contains the 
Original description :—‘ I am indebted to Major Godwin-Austen 
for pointing out that this magnificent slug, the largest yet known 
of the genus, is quite distinct from Benson’s Helic. gigas (Khasi Hills) ; 
Godwin-Austen has kindly undertaken to describe the animal with full 
details and a figure, so that it is only necessary for me here to state 
that it is very closely allied to the Assam species, but that the shell 
is much larger, of a brown (not green) colour, with the body-whorl 
much more flatly expanded, and the spire less convoluted and more
