It is chiefly with regard to its colouration that this Hyena differs from its 

 relative at Kilimanjaro. It is generally of a much paler hue. The snout is less 

 dark, and the forehead is pure grey without any such brownish tint as in H. scMl- 

 lingsi. The sides of the neck from below the ears and backwards are almost pure 

 white. The black longitudinal stripe on either side of the mane on the upper neck, 

 which is strongly developed in H. scMllingsi, is much less conspicuous in the new 

 race and is not continuous but more or less broken up in a series of short streaks. 

 The mane itself is very much lighter than in H. scMllingsi, in which the general 

 colour of the mane, when not erected, is dark brown which is produced by the long 

 blackish brown tips and the brown rings on the individual hairs. In this race again 

 the dark, brown tips do not by far cover the pale brownish to whitish ground colour. 

 The single hairs of the mane are coloured in such a way that the base is almost 

 white for about 4—5 cm., then follows a 5 — 7 cm. broad zone of very pale brownish, 

 then again 2 — 3 cm. whitish and finally the dark maroon brown tips 4 — 6 cm. but 

 in consequence of the great thinness of the latter compared with the middle and basal 

 portions of the hairs they do not cover much with their dark colour. A probably 

 important difference from H. scMllingsi is that in the latter there are often, if not 

 always, several short brown rings alternating with pale in the middle portion of the 

 hair, while in the present race as described above it is only one broad and much 

 paler brownish ring. The tail of the new race is very pale because the dark tips of 

 the hairs are very short and give hardly any impression of dark colour except at 

 the apical end, and the general colour of the hair is huffish white. The general 

 colour of the sides of the body is whitish. The black stripes over the shoulders and 

 hind quarters are decidedly narrower than in H. scMllingsi. The same is also the 

 case with the transverse stripes on the flanks, although they perhaps stand out more 

 boldly in consequence of the lightness of the ground colour. In H. scMllingsi there 

 are two broad black stripes running from the dorsal crest down over the hind quarters, 

 but in the present race there are three such stripes, although much narrower. The 

 middle one of these stripes is less strongly marked than the anterior and posterior. 

 The stripes on the sides of the body are not very sharply defined but have a certain 

 tendency to join to a network or dissolve into spots. The stripes across the legs
