miller] seventy new MALAYAN MAMMALS 47 



The teeth are essentially like those of Galeopithccus z'olaiis, due 

 allowance being made for their smaller size.

Specimens examined. — Two, both from Pulo Adang. 



Remarks. — This small Galeopithecus is so readily distinguishable 

 from the peninsular animal, which for the present may .be assumed 

 to represent true volans, that no further comparison is necessary. 

 From Galeopithecus temminckii as figured by Waterhouse it differs 

 in its smaller size, less wide palate, and much smaller teeth. 



GALEOPITHECUS AORIS sp. nov. 



Type. — Adult female (skin and skull). No. 112,428, United States 

 National Museum. Collected on Pulo Aor, off coast of Johore, June 

 8, 1901, by Dr. W. L. Abbott. Original number, 1028. 



Characters. — Similar to Galeopithecus pumilus but not as small, 

 palate relatively not as broad, and upper canine, lower canine, and 

 first premolar much larger. 



Color. — The type is similar to the type of Galeopithecus pumilus 

 except that the wash of isabella-color is less distinct on feet and 

 outer edge of membranes, and the entire back is tinged with 

 whitish cream-buff. A pale buffy spot on each shoulder and hip. A 



^ Measurements in parenthesis are those of an adult male Galeopithecus 

 volans from the Rumpin River, Pahang (No. 115,493).
