Occurrence of Acantlioglossus in Britiah Keio Guinea. 293 



Anotlier female from the same locality is much redder 

 above, the liair.s ti))|)ed with yellow on the sides and with 

 ferruginous on dorsal region and on thi^^hs; middle of head 

 from a ])oint on the foreliead to occiput blackish brown; back 

 of neck reddish brown like dorsal region ; long hairs on 

 forehead and sides of head ))ale brown ; arms reddish brown, 

 only a little of the pale yellow so conspicuous on the male 

 appearing near' the shoulder ; forearms, legs, hands, feet, 

 underparts, and tail like in the other female. 



These three s{)ecimens resemble those of no species with 

 which 1 am acquainted; the style of coloration is alike in 

 all of them, although the tints vary somewhat from a blackish 

 to a reddish brown. All three are strongly speckled on the 

 lower back, legs, and tail by the light tips of the hairs, but 

 only the male has the very light arms. The hair on the head 

 of the male is short and compressed, but the hair on the head 

 of the females is long, loose, and in the form of a crest 

 standing upright on the forehead and away from the sides of 

 the head. The female last described has the back of the 

 liead reddish brown like the neck, while the other has the 

 crown and nape alike, of a blackish-brown colour. In this 

 respect, however, they merely follow the habit of many 

 species of the genus Cebus, individuals varying greatly 

 among themselves, even from the same locality, in the pattern 

 exhibited on the crown of the head, as well as in the distri- 

 bution and variety of tints on various parts of the body. 



1 am indebted to the courtesy of Mr. OMfield Thomas, 

 Curator of Mammalogy in the British ]\lu.seum, for the 

 0])portunity of describing the above specimens.
