Note. — Having compared tbe original specimen of C. superciliaris, 

 Heugl., with an authentic example of C. chalcopterus from Dama-

The two last species have not been examined by me. 



6. A Revision of the Genera of Pteropine Bats {Pteropidee), 

 and the Descriptions of some apparently Undescribed 

 Species. By Dr. John Edward Gray, F.R.S., V.P.Z.S., 

 F.L.S., &c. 



Some years ago I studied the Bats with care, and described some 

 new genera and species, and commenced a monograph of them, of 

 which my papers were to be only the forerunners. My friend Mr. 

 Robert Tomes took up the study, and seemed inclined to devote con- 

 siderable time to it ; so I retired from the position which he so well 

 occupied, and placed the collection of Bats in the Museum entirely 

 at his disposal, hoping some day that he would prepare a catalogue 

 of them ; and he has produced some excellent papers on isolated 

 genera and geographic groups. He is now so occupied with other 

 business that he has not lately been able to give any attention to 

 the subject. 



I have been working at other groups of Mammalia, and at length, 

 in the course of my duties, the Bats must be catalogued, and there-
