A NEW FLYING-SQUIRREL FROM THE PHILIPPINE 



ISLANDS. 



BY WILFRED H. OSGOOD. 



In a collection of mammals recently received by the Field 

 Museum of Natural History are two flying squirrels from the 

 Philippine Island of Bancalan. This island is of small size and 

 lies in North Balabac Straits between Balabac and Palawan. 

 No natural history collections have been reported from it here- 

 tofore, but as indicated by its location and by the present 

 specimens, its faunal relations are doubtless with Palawan. 

 These specimens, although closely similar to Sciuropterus nigripes 

 of Palawan, differ, from it, chiefly in size, to an extent sufficient 

 to warrant their separate recognition. Comparison has been 

 made with four specimens of S. nigripes from Iwahig, Palawan, 

 kindly loaned by the American Museum of Natural History 

 through Dr. J. A. Allen.

Characters. — General characters as in Sciuropterus nigripes Thomas;*
