situated at the apex of a small conical projection. Mr. Guilding’s de- 
scription of the eggs agrees almost exactly with Pfeiffer’s. 
Should future observations confirm those which Mr. Guilding has 
already recorded, his shells will surely constitute a new genus, singular, 
amongst the fresh-water Pectinibranchia, for the patelliform shells ana- 
logous to Calyptrea and Pileopsis amongst the salt-water Pectinibran- 
chia. In such case also, there would bea singular deviation from the 
usual structure in that order, as the cavity of the branchiz will be not 
immediately behind the neck, but lateral. If so, here again will be a 
remarkable analogy of deviation from the usual form in the order Pecti- 
nibranchia, with Cyclostoma, Helicina, &c., singular amongst the 
Pulmonifera for having the frontal margin of the mantle disunited from 
the neck, and therefore exposing the pulmonary vault. 
Notice relating to Mustela flaviqula, Bodd. By the Hon. Carr. SuHore. 
Tue animal is found to my knowledge throughout Kumoun, Gurhwall, 
and part of Sirmoor, provinces in the hills bordering on the Himaleh, 
extending from the river Kalee to beyond the Jumna, a piece of country 
about three hundred miles long by sixty broad. As it is met with in Nepal, 
which is some hundred miles to the south east of the above provinces, 
it would probably be found in all the hill country which lies between 
them, as it is much the same in surface, climate, and productions, both 
animal and vegetable. It chiefly frequents the warm vallies, but it is also 
found on the higher ridges where the climate is perhaps as warm as the 
middle of France. It is as common as, or perhaps rather more so than, 
the Polecat in England. I never heard of its being seen in the plains of 
India. It lives in holes in rocks, or in trees, in climbing which it is ex- 
cessively active. Its food is chiefly birds, rats, mice, hares, and even young 
fawns of the Kakur, (a species of Deer about 18 or 20 inches high with 
eye-teeth like a dog, and whose cry is like the bark of a small dog.)
