N0.1485. MAMiMALS FROM RHIO-LINGA ISLANDS— MILLER. 251 



Remarks. — Individual variation in color is not very noticeable in 

 this species. In some specimens the light grayish of the inguinal 

 area is replaced by a clear yellowish buff; while in four, including the 

 two from Great Karimon, the light color is intensified almost to a 

 definite white, this taking place also in the axillary region. In one 

 skin (female. Cat. No. 122851) from Pulo Kundur the black of the 

 upper parts is so reduced that the raw- sienna is much in excess.
