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 Calyptraa and Pileopsis amongst the salt-water Pectinibran- 

 chia. In such case also, there would be a singular deviation from the 

 usual structure in that order, as the cavity of the branchiae 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, Hdicina, &c., singular amongst the 

 Pulmonifera for having the frontal margin of the mantle disunited from 

 the neck, and therefore exposing the pulmonary vault. 



Xotice relating to Mustela flavigida, Bodd, By the Hon. Capt. Shore. 



The 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 longby 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.)
