new Squirrel from Burma. 315 



whitlsli, both outside and in. Under surface, from cliin to 

 anus, bright sharply contrasted ochraceous buff (in the type ; 

 the second specimen nearer tawny oclu'aceons). Lateral line 

 of demarcation very sharply marked in both specimens, and in 

 the type emphasized by a blackish line which runs from the 

 middle of the front of the forearm, across the shoulders, down 

 tlie sides and legs to the back of the heel. Fore limbs on 

 outer side above this line of demarcation creamy whitish, 

 like the flanks; beyond it, including the hands and the 

 whole of the inner aspect, ochraceous buffy like the belly, or 

 slightly paler. Back of upper part of hind leg whitish like 

 body; inner side, ankles, and feet buffy like belly, rather 

 paler on the digits. Tail above and below creamy buff 

 proximally (the extreme tips of the hairs blackish), lightening 

 to white terminally. 



Skull of the general proportions of that of S. Finlaysoni^ 

 erythrceus^ &c,, but there is only one upper premolar in the 

 single specimen of which the skull has been preserved. This 

 has the milk-premolar still in place, and the large permanent 

 premolar just coming up below it, but no trace of the small 

 p^, which usually at this stage is readily discernible.

 Head and body 250 mm. ; tail 265 ; hind foot (s. u.) 54 ; 

 ear 22. 



Skull : zygomatic breadth 32 ; back of postorbital process 

 to tip of nasals 325 ; nasals 16'4 x 7"2 ; interorbital breadth 

 18 ; palate length 23 ; length of upper tooth-series 10.

 Moungkan ; a second specimen from Horaalin* About 25° N., 

 95° E. 



Type. Immature male. B.M. no. 5. 8. 11. 1. Collected 

 14th December, 1901, and presented by Capt. li, H. 

 Harington. 



"^J'liis very peculiar squirrel is so entirely unlike any known 

 species that I do not know with what to compare it. Its pale 

 creamy-buff colour and whitish tail are quite unique, while 

 no other Oriental squirrel of its size is without the small 

 upper premolar. This latter character also indicates that 

 Sciurus Haringtoni is not merely a partially albinistic variation 

 of some known species, an explanation wliich its pale colour 

 might at first sight suggest. 



Capt. Harington is to be congratulated on the discovery of 

 so striking a new form.
