EAST ATRICAN MAMMALS IN NATIONAL MUSEUM. 11 



HEUOSCIURUS RUFOBRACHIATUS NYANS^ (Neumann). 



1902. Sdurus nyansae Neumann, Sitz.-ber. Ges. nat, Freunde Berlin, 1902, p. 

 56. (Kwa Kitoto, Kavirondo [Kisumu], British East Africa; type in 

 Berlin Museum.) 



Specimens. — Eighteen, from localities as follows: 



British East Africa: Kaimosi, 14 (Heller); Liikosa River, 4 

 (HeUer). 



Included in the Kaimosi series are small yomig without cheek teeth, 

 taken January 26 and 30; and half-groAvn young collected February 

 4. The adults, collected in late January and early February, are 

 mostly in full fresh pelage, but a few show very nicely the process of 

 renewal. One collected January 28 has the anterior half, above and 

 below, wdth the exception of a narrow band across the occiput, in 

 fresh coat. There is considerable variation in the color of the feet in 

 the Kaimosi series — from ochraceous orange to bright chestnut. 

 When the extremes in color are brought together the difference is very 

 striking. 



HEUOSCIURUS KENI^ (Neumann). 



1902. Sciunis keniac Neumann, Sitz.-ber. Ges. nat. Freunde Berlin, 1902, p. 

 176. (West side of Mount Kenia, British Fast Africa, at 8,000 feet: tj-pe 

 in British Museum.) 



1910. Helrosdurus henin: Roosevelt, African (rarne Trails, Amer. ed., pp. 472, 



470; London ed., pp. 484. 488. ^ 



Specimen. — One, from— 



British East Africa: West slope Mount Kenia at 7,000 feet 

 (Heller). 



This specimen, an old female, has the characteristic blotch of white 

 on the underside of the neck, to between the forelegs. The hands and 

 feet are colored like the back, with no indication of rufous or ochra- 

 ceous beyond the pale ochraceous buff speckling of the hair tips. The 

 species is a member of the nifohracliiatus group, but I am not aware 

 that any specimens have been taken to prove intergradation with 

 H. r. nyansse.
