 No. 17, p. 1. February 28. (Uma. Uganda; type in U. S. Nat. Mus.) 



Specimen. — One, the type: 



Uganda: Uma (K. Roosevelt). 



This specimen was shot in a clump of bamboo. 



HELIOSCIURUS MULTICOLOR LATERIS Thomas.

Specimen. — One, from — 



Lado: Rhino Camp (T. Roosevelt). 



This specimen is imperfect; the forward part, with skull, is missing, 

 and it is impossible to make satisfactory comparison with the type 

 of Heller's madogse. The Lado specimen is, however, less buffy 

 below than the specimen from the east side of the NUe.

 (P. emini.) [Valid as a subgenus.] 



Three groups of squirrels in the East African collection are combined 

 under the genus Paraxerus. The hoeJimi group includes small, sharply 

 striped species represented only by a specimen from Uganda; the 

 paUiatus group, larger species superficially resembling certain forms 

 of Heliosciurus undulatus; and the medium sized scrub-squirrels, 

 ochraceus and its subspecies, are represented by several forms. 

 These last are closely related to the type-species of the genus, Paraxe- 

 rus cepapi of South Africa, but are uniformly smaller and usually 

 show traces of the back-stripes so conspicuous in the hoehmi group, 

 but wanting in cepapi and paUiatus. Thomas has proposed that the 

 hoelimi group be recognized as a distinct genus, Tamiscus; but the 

 characters separating this group from typical Paraxerus are shght and 

 the relationship is very close. I should not be wilUng to admit more 

 than subgeneric rank for Tamiscus. 



For measurements of specimens of Paraxerus see pages 17-19.
