574 On the Ochre-footed Scrub- Squirrels of East Africa. 



subspecific rank, as the three species named are such very 

 widely separated forms inter se. Dr. Matschie (SB. Ges. nat. 

 Freund. 1894, p. 256) disregards these two species entirely, 

 giving the former name as a synonym of S. Cepapi^ and 

 describes a specimen as S. Pauli from a living animal sent 

 home from Tanga and the skin of a very young individual 

 from the same neighbourhood. 



S. Cejmpi, a larger and stronger animal, only occurs south 

 of the Zambesi Eiver; northward in Mozambique the bright- 

 coloured striped squirrel S. flavivittis is found ; north of the 

 Rufigi River the faintly striped S. ochraeeus occurs at Dar-es- 

 Salaam, Bagomoyo, and in Usagara. The side stripe of 

 this latter species, which at all times is very faint, varies 

 much in distinctness, as is well shown in the series in our 

 Museum ; in some specimens it is scarcely perceptible and 

 would, in all probability, be overlooked unless expected. 

 The forms from Pangani and Tanga, agreeing with the last- 

 named in having a dull greenish-white belly, have been 

 described as stated above, and if, as I suppose, S. aruscensis 

 belongs to this group, it is ditficult to see how S. Pauli can 

 be made out distinct, if, indeed, either are separable from 

 S. ochraeeus. 



About Mombasa and inland as far as 6000 feet on Kilima- 

 njaro, and northward in the coast region, we find the orange- 

 bellied form which has lately been described by Mr. S. Rhoads 

 (Proc. Ac. Philad. 1896, p. 522) as S. ganana. In the high- 

 lands of Kikuyu we find yet another form, very dark in 

 colouring and rather larger than its allies ; this species I 

 have pleasure in naming S. Jachsoni^ after the distinguished 

 explorer, Mr. F. J. Jackson, who presented the specimens 

 to the Museum and has done so much in adding to our know- 

 ledge of the fauna of East Africa in several branches of 

 zoology. I think there can be little doubt that the squirrel 

 mentioned by Mr. Rhoads {t. c. p. 521) from Marsabit, an 

 eastern oflfshoot of Mount Kenia, is of this species. 



Sciurus JacJcsoni, sp. n. 



General colour dark olive-green, slightly washed with 

 brown ; the face, rump, upper arms, and legs with a rather 

 stronger brown tint ; tlie feet and hands more or less grizzled 

 rufous orange or rust-coloured ; a broad buff stripe above and 

 below the eyes ; cheeks and ears grizzled of the general 

 body-colouring ; on the sides the dark colouring of the upper 

 parts gradually passes into that of the ])alcr underparts, the 

 centre line of the chin, throat, and belly and the inner sides of
