already described, and an excellent figure of the former given by 

 Dr. Anderson.* The following are further details of the subspecies 

 I recognize. 



Sciurus sladeni sladeni, Anders. 



Syn. S. hemmisi, Wrought. 



Muzzle rich ferruginous nearly to the level of the ears, cheeks 

 below eyes also ferruginous. Feet bright ochraceous (nearest to 

 zinc orange or apricot orange of Ridgway). 



Localities. — Tigyaing (Anderson) ; Katha (Kemniis.) 



Soiurus sladeni midas, subsp. n. 



As true sladeni, but the ferruginous of muzzle not extending on 

 to forehead, or on to cheeks below eyes. Feet darker (ferru.ginous 

 of Ridgway). 



Oondylo-incisive length of skull, 51-5 ; p. 4 and 3 molars 10-1. 



Locality. —Mjitkinsi. Alt. 600'. 



Type.— Adult male. B. M. No. 11.7.31.1. Collected 2nd May 

 1911 and presented by A. W. Kenimis, Esq. 



Sciurus sladeni ruhex, subsp. n. 



Like S. sladeni midas in the small extent of the rufous of the 

 muzzle, the olive-grey cheeks, and the tone of the feet, but with the 

 whole of the back strongly suffused with dark rich ferruginous, this 

 suffusion also extending in a lesser degree on to the tail. Sides 

 grey, ticked with buffy. Terminal third of tail deep ferruginous. 



Dimensions of the type, measured in flesh : — 



Head and body 214 mm; tail 254; hind foot 54; ear 22. 

 Condylo-incisive length of skull 49*5 ; p. 4 and three molars 9'6. 



Hab. — Lonkin, Myitkina District. 



Type.—Advlt male, B. M. No. 14.4.3.7. Original number 50. 

 Collected 22nd February 1914. Presented by Capt. F. E. W. Ven- 

 ning through the Bombay Natural History Society. 



Readily distinguishable from the other forms of this group by the 

 warm ferruginous suffusion of the upper surface. 



Sciurus sladeni hartoni, subsp. n. 



General pattern as in sladeni, but the muzzle, hands and feet are 

 " warm buffy " instead of ferruginous, and, just as in 8. haringtord 

 haringtoni, there is a distinct narrow blackish line separating the 

 grizzled olive of the upper parts from the rich ochraceous buff of 

 the belly and inner sides of the limbs ; this line crosses the forearm 

 half way down, but is not evident on the ankles. Terminal third 

 of tail (instead of the usual fifth or sixth) rich ferruginous. 



Dimensions of type, measured in flesh. — Head and body 227 mm; 

 tail 260 ; hind foot 51-5 ; ear 21-5.
