which had formed quite a large hole in the membrane and laid bare the muscles of the 

 humerus. The disability caused by the wound and being hampered by the young 

 one were the probable cause of its capture by the hawk. Both the hawk and the 

 kubong were brought to me alive that same evening by the Malays who caught them. 

 I have seen Spizaetus try to catch Ratufa, but I never saw them succeed. 



GALEOPTERUS ABBOTTI, new species. 



Type.— Skin and skull of adult female, Cat. No. 145577, U.S.N.M., 

 collected on Pulo Panebangan, off west coast of Borneo, May 16, 1907, 

 by Dr. W. L. Abbott. Original number, 5231 



Diagnostic characters. — A small member of the genus, much smaller 

 than the flying lemur from the adjacent island of Borneo, and even 

 smaller than G. gracilis Miller l from Sirhassen, Natuna Islands. 



Color. — The color of Galeopterus abbotti is essentially like that of 

 G. borneanus described above. 



SJcull and teeth.— The chief peculiarity of the skull of G. abbotti is 

 its small size. In addition to that it is a rather flat skull, with mod- 

 erately pinched-up nasals and rather shriveled and shrunken mas- 

 toids. The teeth show no peculiarities, but are proportionately as 

 small as the skull. 



Measurements. — See table below. 



Specimens examined. — Two, the type and a young male preserved 

 in alcohol. 



Remarks. — Galeopterus abbotti has the smallest skull of any female 

 flying lemur in the National Museum. It is nearly but not quite as 

 small as the skull of the type, a male of G. pumilus Miller 2 from the 

 Adang Islands. The skin of single specimen of G. abbotti shows well- 

 developed mammas, so that there can be no question as to the sex of it.
