7. Notice of Notopteris, a New Genus of Pteropine Bat 

 from the Feejee Islands. By Dr. John Edward Gray, 

 F.R.S., V.P.Z.S., etc. 



(Mammalia, PL LXVII.) 



Among a large collection of the skins of Mammalia, Birds. Fishes, 

 Crustacea, &c, sent to the British Museum by the Lords of the 

 Admiralty, which were collected by Mr. Rayner, Dr. Macdonald, 

 and the Medical Officers of H.M. Ship ' Herald,' during the voyage 

 to the Feejee and other Pacific Islands, under the direction of Captain 

 Denman, R.N., there are two specimens of a small Pteropine Bat 

 from the island of Viti, which has the elongated face and the general 

 appearance of the Kiodote (Macroglossus), but is provided with an 

 elongated, free, slender, tapering tail, nearly as long as the hind legs, 

 which, like the tail of most Bats having this member enclosed in 

 the interfemoral membrane, is arched, the tip being bent ventrally 

 or downwards. 



Considering that the best genera of Bats are those established on 

 the external conformation of the members, I am inclined to propose 

 for this animal a new generic designation ; and I have no doubt that, 

 when its habits and manners are known, they will be found to differ 

 considerably from those of Macroglossus and Cephalotes, to which it 

 is most nearly allied. 



Notopteris.

 muffle narrow, bald between the nostrils, with a deep central notch. 

 Ears small, lateral. Body covered with rather crisp hair. Wings
