greyish brown. The hairs of the tail are white with very- 

 short black tips. The f'eet are dirty whitish brown. This 

 agrees in some respects with Matschie's account of H. h. 

 bergeri. For geographical reasons, however, and pending 

 the arrival of sufficient material for a judgment to be formed 

 as to individual variation in this genus_, I have placed the 

 specimen under the earlier name. 



It may be noted that the skull of K. QQ shoAVs the second 

 upper premolar in the diagonal position mentioned by 

 Hollister in his paper on " East African Mammals ^' (Bull. 99, 

 Smithsonian Inst. U.S. Nat. Mus. part i. p. 140, 1918).

In this fine series of spotted hysenas, there is an immense 

 range in colour-variation. No two skins are alike, even 

 those from the same locality. Age seems to be the domi- 

 nating factor. The young in this series are grey with a 

 brown dorsal tinge, black spots, dark brown feet, and long 

 hair. The old are buff and white, with greyish-brown or 

 russet spots, white or cream-buff feet, and very short hair. 

 In the transition-period from youth to old age, the ground- 

 colour appears to pass from grey to russet, clay-colour, and 

 tawny, becoming lighter till the buff and white of old age is 

 i"eached. The spots, which vary in size and regularity, 

 change gradually from black to dark russet and grey-brown. 

 The long hair of youth becomes short and mangy-looking 

 in old age, while the feet change from black-brown to cream- 

 buff or white.
