The proi)er treatment of this most interesting bat is a 

 difficult problem, and other naturalists may think it might 

 have been assigned to one of the previously known genera. 

 But it appears to me that genetically it is a gigantic Serotine, 

 and if this be the case to put it in Fipistrellus would be 

 absurd, while to put it with the Serotine in Vespei-tilio would 

 be to ignore the convenience, now generally recognized, of 

 considering the presence or absence of the anterior upper 

 premolar as by itself of generic importance. 



I'o the Serotine it is related by its general form, the propor- 

 tions of its ears and tragus, and the structure of its incisors 

 and molars ; and its retention of the little premolar above is 

 the only point in which it agrees with the Pipistrelle. Its 

 large, strongly curved claws are peculiar to itself. 



Mr. Styan is to be congratulated on this interesting addi- 

 tion to the many Chinese mammals in whose discovery he 

 has been instrumental.

Size small, only exceeding the little C. Styani, de V/inf., 

 of Sze-chuen, and markedly less than in C. himakiica, Gray. 

 General colour a rather paler, more slaty, and less blackish 

 grey than in C. himalaica ; but, as in all the members of this 

 genus, the difference is trifling. Under surface uniformly
