diversity worthy of notice. The following description is drawn up 

 from specimens received from Agra and Mirzapore. Entire length, 

 (of a full grown male,) to end of the long slender tail, five inches and 

 a half, the latter passing the membrane by two inches and a quarter ; 

 expanse twelve inches and a half: (length of a female five inches, by 

 eleven inches in expanse:) fore-arm two inches and a quarter; longest 

 finger two and three-quarters; tibia an inch and a quarter: foot 

 with claws five-eighths of an inch ; ears from base anteally seven- 

 eighths of an inch, posteally half an inch, and width of the joined 

 pair, from tip to tip, an inch and seven-sixteenths. Fur very fine and 

 delicate, its general colour a soft dull brown, paler at base, where 

 inclining towards albescent ; the face, rump, and abdominal region 

 naked, the skin of the rump corrugated, and together with the face 

 and membranes dusky, having a tinge of plumbeous ; the skin of the 

 arms underneath, and of the belly and nates inferiorly, is transparent, 

 the latter covering an enormous accumulation of fat, which above 

 reaches over the loins and along the spine. Nostrils closed and val- 

 vular, forming obliquely transverse slits in the truncated muzzle : the 

 claws conspicuously white. 



Dysopes. I know of but one Indian species of this genus, which is 

 the Vespertilio plicatus of Buchanan Hamilton, Lin. Trans. V, 261 ; 

 the Nyctinomus bengalensis of M. Geoffroy ; and I am inclined to 

 regard the D. murinus of Hardwicke's published drawings as no 

 other, indifferently represented. 1 was favored with a live specimen 

 of this animal by Mr. Ridsdale, of Bishop's College Press, and lately 

 obtained another which flew in at a window : Mr. Masters also has 

 presented the Society with a stuffed one : all of these being much 

 of a "snuff-brown" colour, the fur of the under-parts tipped paler: 

 but there is an old specimen of what may perhaps be another species 

 in the museum, the fur of which is remarkably close and velvety, 

 and very dark fuliginous- brown above, with a shade of maronne, 

 the under-parts similar but paler and somewhat reddish. So far as I 

 can judge from the state of the specimen, it presents, however, no 

 structural characters at variance with those of the other, that can 

 warrant its being distinguished as a species; but I yet suspect that it
