SCIURUS CONlilCLtJ. 35 



The specimens agreeing with Sciums jiavivittis Peters are 

 colored as follows: the hairs of upper surface of head? 

 neck and back are black with a subapical rusty ochraceous 

 ring. Hairs of the sides of the body and outside of legs 

 black at the base and for the rest light ochraceous brown 

 or slightly black tipped. A band darker colored than the 

 back and running from slioulder to thigh cuts from each 

 light ochraceous brown colored side of the body a smaller 

 band colored much lighter than these parts. Chin, throat, 

 breast , belly and inside of legs covered with yellowish white 

 hairs , at the base of the hairs nearly always blackish. Hairs 

 of tail ochraceous yellow , ringed with black. Inside of the 

 well developed ears ochraceous , outside whitish ; behind the 

 ears a whitish spot. The dark-brown eyes arc surrounded 

 by a whitish circle. Whiskers black. 



JSome specimens from Angola present a mode of colora- 

 tion just iutermediate between Sciurus i-ongicus Kuhl and 

 the ochraceous form described as Sciurus Jlavivittis.

1) Prof. Peters called my attentioD to the fact , that there is in the Ber- 

 lin Museum a skull of a Sciurus con^icus which shows the molars more worn 

 out thau those in a skull of a Sciurus flaoicittis, although the latter belongs 

 to au older individual. He therefore believed that Sciurus coiigicus and Sciu- 

 rus Jlavivittis are two distinct species. But in my opinion the more or less 

 worn-out aspect of the molars can be a consequence of age, but it uocd not 

 (ilivays have the same reason, as it can also be a mere local phenomenon, 

 resulting for instance from the nature of the food.
