EAST APEICAN MAMMALS IN NATIONAL MUSEUM. 15 



Specimen. — One, from — 



Uganda: 22 miles west of Kampala (Heller). 



No specimen of Paraxerus emini from the type locality is available 

 for comparison. Thomas^ and DoJlman^ consider the two forms 

 identical and Dollman has listed specimens of emini from Entebbe, 

 Uganda, not far from where our specimen was collected, and at the 

 type locality of ugandse. In a review of the forms of the group pub- 

 lished in 1918,' Thomas formally places ugandse. as a synonym of 

 emini. 



PARAXERUS PALUATUS SUAHEUCUS (Nenmann). 



1902. Sciurns palliatus suahelicus Neumann, Sitz.-ber. Ges. nat. Freunde Berlin, 

 1902, p. 178. (German East Africa opposite Zanzibar and southern part 

 of British East Africa; no type designated.) 



Specimens. — Twelve, including one in alcohol, as follows: 



British East Africa: Mazeras (Heller). 



Except for one specimen with a pale ochraceous tail, the skins in this 

 series present a very uniform appearance. 



Our collection contains no specimens of Paraxerus palliatus palliatus, 

 but comparison of suahelicus with Paraxerus palliatus ornatus leaves 

 me rather dubious as to the conspecific relationship of these two forms. 

 Without material representing the intermediate type, however, it 

 seems best to leave the form as usually placed by authors. 



PARAXERUS OCHRACEUS ARUSCENSIS (Pagenstecher). 



1885. Sdunis cepapi Smith var. aruscensis Pagenstecher, Jahrb. Hamb. Wiss. 

 Anst., vol. 2, p. 42; Nat. Mus. Hambm-g Ber. 1884, p. 42. (Pangani 

 River near coast, and Great Aruscha, Meru Mts., German East Africa.) 



1892. Sdurus poensis True. Proc. U. S. Nat. Mus., vol. 15, p. 467. (Not of 

 Smith.) 



Specimens. — Thirty-one, as follows : 



British East Africa: Changamwe, 18, including 4 in alcohol 

 (Mearns); Maji-ya-chumvi, 3 (Heller); Mount Kilimanjaro, 1 (Ab- 

 bott); Mount Sagalla, summit, 1 (Heller); Mtoto Andei, 1 (Heller); 

 Ndi, 1 (Heller); Taveta, 5 (Abbott); Voi, 1 (Heller). 



Only one race is represented in the series listed above. At first 

 sight the Taita Hills lot appears somewhat lighter colored, grayer 

 above and less ochraceous below, but a careful study of the speci- 

 mens convinces me that they can not be separated from the Taveta or 

 the coast series, which are surely identical. The extreme gray example 

 in the Maji-ya-chumvi series is an aged female, lately nursing, and 

 the only grayish specimen in the Taveta series proves to be the next 

 oldest specimen of the entire thirty-one examples, and also a 

 nursing female. The grayish "phase" of coloration in aruscensis 

 may be a condition of pelage of old age, or of nursing females. Cer-
