' Dysopes. — I know of but one Indian species of this genus^ 

 which is the Vesjjertilio plicatus of Uuchanan liamiUon^ Linn- 

 Trans. V. 261 ; the Nyctinomus bengulensis of Al. Geoffroy ; 

 and 1 am inclined to regard the D. murinus of Ilardwicke's pub- 

 hshed drawings as no other, indifferently represented. I was 

 favoured with a live sj)ecinien of this animal by j\lr. Kidsdale, of 

 Bishop^s College Press, and lately obtained another which flew in 

 at a window : Mr. Masters also has ])resented the Society with a 

 stufFeil one : all of these being much of a " snuff-brown" colom', 

 the fur of the under -parts tipped paler : but there is an old spe- 

 cimen of what may perhajjs 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 maroon, the under- 

 parts similar, but paler and somcMhat reddish. So far as I can 

 judge from the state of the specimen, it ])resents 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 is a different species from the plicatus^. The affinity of 

 this genus for Taphozous is wavy apparent in the living or recent 

 specimens, the present group having even the same peculiar 

 mode of folding the wings, which is not the case even with Rhi- 

 nopoma, wherein there is merely a tendency or inchnation to 

 that particular mode of duplicature of the wings.
