LOCALITIES. Sumatra, Java. 



DESCRIPTION. The face of an adult male in the Paris Museum 

 is short, and of a brownish tint, with short, thinly - set grey hairs ; 

 the fur of the body consists of a soft, woolly, fine, but not very 

 full, undercoat of greyish-white hairs, and of an outer vest of long, 

 fine, silky hairs, loosely flowing (many of the length of five inches), 

 and of a blackish colour, the general tint, resulting from the mixture, 

 being a fine plumbeous grey ; the hairs of the head form a compressed, 

 ridged crest, somewhat peaked anteriorly ; the top and sides of the head 

 and the crest are dull black, with a brownish tint, losing itself in the 

 plumbeous grey of the back ; the shoulders and arms, externally, are of a 

 deeper grey ; the hands and feet are nearly white, with dark hairs inter- 

 spersed ; the tail is dark grey above, white beneath and at the tip, which 

 is somewhat tufted ; the inside of the arms, and of the thighs and legs, 

 is abruptly pure white ; which is the colour of the chin, whiskers, throat, 

 and under surface of the body.

An adult female, in the same museum, is similar, in colouring, to the 

 male. Both were brought from Java, by M. Diard. 



A nursling, also from Java, covered with delicate woolly fur, is alto- 

 gether white, excepting a patch on the vertex (where the crest indicates 

 itself), and down the spine, and along' the upper surface of the tail, the 

 hue of these parts being leaden black, or black with a tinge of grey. 



It is, probably, to the present species that the " Guenon gris-blanc," 

 or " Cercopithecus albo-cinereus," of Desmarest (Supp. p. 534'), is refer- 

 able ; though, in some points, certainly, his description does not agree 

 with it. Desmarest's characters and description are as follow : 



" GUENON GRIS-BLANC, Cercopithecus albo-cinereus (not figured). 

 A new species, from the collection preserved in the Museum, and brought 

 by MM. Diard and Duvaucel. 



" Specific Characters, Fur, grey above, and of a deeper tint on the 

 loins than elsewhere ; the under parts whitish ; a line of stiff black
