long tail terminates in a white tuft. The contrast of the white of the mantle 
cheeks, and tail against the velvety black of the rest of the body is most striking 
and without exact parallel among other mammals, although the coloration of the 
skunk is somewhat suggestive of it. 
Handsome as is the ordinary guereza in these respects, it is, however, exceeded 
by a variety occurring commonly at an elevation of about three thousand feet on 
the flanks of Kilima-Njaro, while the common race is believed to exist in the 
plains around. In the common guereza the first 12 or 16 inches of the tail are 
black and short-haired, the white tufted portion including only the last 8 or 10 
inches; while the white mantle of hair depending from the back conceals only

about one-third of the black portion of the tail. In the Kilima-Njaro variety, or 
large-tailed guereza, only some 3 or 4 inches of the base of the tail are black and 
short-haired, while the remainder is covered with long white hair for a length 
of some 20 inches, each individual hair measuring from 8 to 9 inches. Moreover, 
the white hairs of the mantle entirely conceal the black of the root of the tail, so 
that the mantle and tail-brush practically become continuous. The tail of this 
variety reminds us of the larger tail of half-bred yaks used in India as fly 
flappers, under the name of chowris; and indeed the whole arrangement of the 
long hairs of the guereza, as well as its coloration, recalls a half-bred yak. 
The guereza has never been brought alive to this country. One 
of the earliest accounts of its habits is given by Pearce in his Life 
and Adventures in Abyssinia, in which it is stated that guerezas are common
