color. The entire back is sprinkled with silvery whitish hairs which 
are most conspicuous anteriorly. Mantle, head and entire underparts 
ochraceous buff, brighter than that of back and strongl}^ tinged with 
tawny on chest, sides of neck, and middle of breast and belly. Face, 
cheeks, and chin grizzled hair brown. Ears and membranes blacldsh. 
Skull and teeth. — The skull and teeth show a remarkable likeness 
to those of Pterojjus lepidus, though immediately distinguishable by 
their much smaller size. The interorbital region is, however, actually 
broader than in the larger species, and the postorbital processes are 
more robust. Pterygoids distinctly convei'gent posteriorly, imparting 
to outline of interpterygoid space a distinctly lyrate foiiii. The teeth 
both above and below agree almost exactly with those of Pteropus 
lepldus., except that the cusps are not as high and the crown is rela- 
tively wider between the cusps.

(5.6 by 3); crown of first lower molar, 3.6 by 2 (4.4 by 2.4). 
Specimens examined. — One, the type. 
Remarks. — Pteropns fannulus is a very strongly marked species, 
easily recognized by its small size and pointed ears. The single speci- 
men was shot in dark forest. It was apparently not very common. 
Pteropus nicaharicus^ originally described from a Car Nicobar speci- 
men was not found on the island by Dr. Abbott.

There appears to be little doubt that a large Pteropus, not P. nico-
