.distinctly convergent posteriorly, imparting to outline of interpterygoid space 

 a distinctly lyrate form. The teeth both above and below agree almost 

 exactly with those of Pteropus lepidus, except that the cusps are not as high 

 and the crown is relatively wider between the cusps. 



Measurements. — External measurements of type (from well-made skin). 

 Head and body, 170 mm. ; tibia, 38 ; foot, 34 ; calcar, 13'6 ; forearm, 

 110 ; thumb, 49 ; second digit, 82 ; third digit, 220 ; fourth digit, 168 ; 

 fifth digit, 153 ; ear from meatus, 22 ; ear from crown, 19 ; width of ear, 14. 



Cranial measurements of type : Greatest length, 54 mm. ; basal length, 48*6 ; 

 basilar length, 46 ; median palatal length, 28 ; palatal breadth (between ante- 

 rior molars), 9 ; zygomatic breadth, 28 ; least interorbital breadth in front 

 of postorbital processes, 7 ; least interorbital breadth behind postorbital 

 processes, 7'6 ; breadth between tips of postorbital processes, 19 ; greatest 

 breadth of braincase above roots of zygomata, 20'2 ; greatest depth of brain- 

 case, 17'6 ; occipital depth, 11"6 ; depth of rostrum at middle of diastema, 

 7"8 ; mandible, 40 (50) ; maxillary toothrow (exclusive of incisors), 19 ; mandi- 

 bular toothrow (exclusive of incisors), 22 ; crown of first upper molar, 3"4 by 

 2*6 ; crown of first lower molar, 3"6 by 2. 



Specimens examined. — One, the type. 



Remarks. — Pteropus faunulus is a very strongly marked species, easily reccg- 

 nized by its small size and pointed ears. The single specimen was shofc in dark 

 forest. It was apparently not very common. Pteropus nicoharicus, originally 

 described from a Car Nicobar specimen, was not found on the island by 

 Dr. Abbott.

Characters. — Similar to the Macacus ' cynomolgus ' of the Malay Peninsula 

 but much darker and less yellowish in colour. General hue of upper parts 

 hair-brown, the hairs with faint pale annulations, but with no trace of tawny. 

 Co^owj*.— Upper parts and outer surface of limbs nearly uniform hair 

 brown, with a faint tinge of drab, the latter becoming more pronounced on 

 sides. About 3 mm. below the tip of each hair is a dull cream buff annula- 

 tion 3 mm. to 4 mm, in width. These light rings, together with the glosey 

 texture of the hairs, give the fur a changing aspect as viewed in different 

 lights. They are slightly more numerous on crown, nape, buttocks, and poste- 

 rior surface of thighs than elsewhere. On the crown and nape they are
