This species iu many points resembles the foregoing , 

 except the pure white streak along each side from the 

 shoulder to the upper part of the thigh , of which streak 

 there is not a trace in Xerus rutilus: a closer inspection 

 however furnishes the following remarks : the general co- 

 lor is the same as in Xerus rutilus , we even find here the 

 three tinges above noticed, viz: straw-color, a more fleshy 

 tinge and blackish-brown ; the first mode of coloration being 

 peculiar to the type-specimens of this species , the third to 

 Xerus congicus Temminck (non Kuhlj, whereas I observed the 

 second color in a specimen from Sudan , collected by v. Heu- 

 ghn and now in the Stuttgart-collection, and also in an 

 individual in the Darmstadt Museum and in another in 

 the Mainz Museum. 



In all specimens there is a more or less important num- 

 ber of wholly blackish brown hairs irregularly planted 

 among the other hairs. The hairs on the back are somewhat 

 longer than in Xerus rutilus and although channelled the 

 grooves are not so clear and the hairs less rigid. Each hair 

 has a yellowish brown tip and the side of the hair turned to- 

 wards the body has the point similarly colored and is for 

 the rest glossy white The hairs of the tail present the 

 following coloration: each hair is reddish brown at its;
