Although I have treated the Chinese si)ecimens as varieties of the 

 Indian species, I hold it by no means j)roved that my first impres- 

 sion was not the correct one. The differences may be thus sum- 

 marily stated: — 1. The ears of the Chinese examples are more dee|)ly 

 hollowed out exteriorly. 2. The tragus is more acute. 3. The 

 tip of the tail is free. In the Indian specimens the ears are less 

 strongly emargiuate, the tragus is sub-acute at the tip, and the tail 

 wholly enclosed in the membrane ; at least it is so in the specimen 

 in spirit. The great difference in colour may perhaps be due to the 

 influence of climate. 



Without a greater number of examples for examination, and espe- 

 cially without an investigation of their crania and dentition, it is 

 difficult to decide with certainty whether this is merely a remarkable 

 variety, or a distinct species. Should it however prove to be distinct, 

 I propose for it the name I at first made use of to designate it, viz. 

 Vesp. rufo-iiiger.

The original specimen from which Mr. Waterhousc took his de- 

 scription having passed into my hands at the dispersion of the Mu- 

 seum of the Zoological Society, I have been enabled to examine it 

 attentively, and to compare it with Mr. Hodgson's specimen of V. 

 formosus in the British Museum, from which it at first sight appears 

 to differ only in being a little larger. On more careful examination 

 if proves to be quite an immature individual, so that if full-grown it 

 would probably differ considerably in size from that species. Again, 

 the number of the teeth appears to be different — different at least from 

 the account given by Mr. Ilodgson of the dentition of V. formosus.
