General remarks. — Cynopterus angulatus bears a strong resem- 

 blance to C. marginatum, but is readily distinguishable by its consid- 

 erably smaller size and by the form of the ear. It is larger than C. 

 brachysoma, the only other known species with similarly formed 

 ear, and quite different in color. 



This bat is represented in Dr. Abbott's collection by two skeletons, 

 three skins with skulls, and six specimens in formalin. 



Khinolophus trifoliatus Teinnrinck. 



Four specimens in formalin. For measurements see table. 

 Rhinolophus affinis Horsfield. 



Four specimens in formalin.

Hipposideros larvatus (Horsfield). 



One skin and ten specimens in formalin. 



The form occuring in Trong differs considerably from the Hippo- 

 sideros larvatus of Dobson and Blanford, which is represented in the 

 National Museum collection by two specimens (in alcohol) taken at 

 Bhano, Upper Burma, by Fea. As the type of Phyllorhina lar- 

 vata Horsfield came from Java, the probabilities are that if either 

 of the mainland forms is referable to the typical subspecies, it is the 

 one inhabiting the southern half of the Malay Peninsula. Assum- 

 ing this to be the case, the form of Hipposideros larvatus found in 

 Assam and Upper Burma is unnamed. As compared with the 

 northern and better known form, that from Trong is slightly smaller 

 in general size. The foot is disproportionately smaller, and the ear
