APES AXD MONKEYS. 



long tail temiinates 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 conunouly at an elevation of about three thousand feet on 

 the flanks of Kilima-Xjaro, 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 wliite 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-Xjaro varietj', 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 wliite hair for a length 

 of some 20 inches, each individual hair measurintj from 8 to 9 inches. Moreover, 

 the white haii-s of the mantle entirely conceal the Vjlack 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 choicris; and indeed the whole arrangement of the 

 long hairs of the eruereza, 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
