SCIURUS ADANGENSIS sp. nov.

 191, December 21, 1900. Part, specimens from Pulo Adang. Not

Characters. — Like Sciurus lancavcnsis but smaller. 



Color. — The color so closely resembles that of Sciurus lancavensis 

 as to require no special description. The sides of the neck are 

 almost exactly concolor with back, and I can detect no trace of a 

 reddish area along sides of body. 



Skull and teeth. — The skull is shorter and relatively broader than 

 that of Sciurus lancavensis, but otherwise it does not differ appreci- 

 ably in form. Teeth as in the related species.

 294. 



Characters. — Similar to Sciurus daz'isoni (Bonhote) from south- 

 ern Tenasserim, but smaller and darker. 



Color. — Type : back a fine grizzle of black, buff, and raw-sienna, 

 the last slightly in excess of either of the others. On sides of neck 

 and along sides of body from axilla to inner surface of thigh the 

 color deepens nearly to ochraceous-rufous which forms a very evi- 

 dent contrast with the surrounding parts. Ears, head, legs, 

 and feet grizzled gray, somewhat resembling the mouse-gray 

 of Ridgway but with a silvery gloss. Underparts dull smoke-gray,
