MannimLs fmm I^tni and lioltvid. 17'J 



iiiiitcly as Hgurc'd Xty 8|iix in liis C tnacrocephalus*. Chest 

 and throat yellow. Forearms and legs bhickish ; fingers and 

 toes white. 



From other evidence it is clear that Mr. Bridges did some 

 collecting in South-eastern Peru, so tiiat species described as 

 Irom " Bolivia — Bridges " may in some oases, as in that of 

 Ctenomys opimus nirfriceps'^^ be really Peruvian in origin. 



Ccbus jiavescens cuscinus, subsp. n. 



Closely allied to C. Jiavescens, Grciy, butwitli a large bruwii 

 coronal patch. 



F^ur of face much lon<rc'r than in most Cebi, there beinjr no 

 peripheral short-haired portion. Hairs on forehead and 

 cheeks smoothly directed backward, those on the crown upright 

 or slightly reversed, though not forming any marked crest or 

 horns. General colour of back pale brown, with a suffusion 

 of rufous. Each hair is pale slaty at base, with a dull pale 

 red intermediate portion and a brown tip; posteriorly on the 

 rump the rufous increases in depth and intensity, passing 

 gradually on to the rich rufous of the hind limbs. Throat 

 and chest uhitish ; belly (the hairs of which are reversed 

 forward.") bright orange-rutbus, continuous with the rufous 

 legs. Hairs of forehead and cheeks pale glossy yellowish, 

 the tips of the hairs browner. Square patch covering crown 

 (about 2 inches broad and rather more in length) dark chocolate- 

 brown, the bases of the hairs pale brown. Ears well clothed 

 with shining yellowish hairs. Fore limbs pale brown above, 

 passing into rufous on the forearm and whitish on the 

 fingers; their inner sides bright rufous to the wrists. Hind 

 limbs rich rufous loth on their outer and inner sides, the toes 

 dull whitish. Tail bushy, the bases of the hairs proximally 

 rufous, terminally white, the tips of the hairs inconspicuously 

 brown. 



Altogether the colouring of the body and limbs is not unlike 

 , that ot the monkey figured by F. Cuvier as the " Sajou h 

 pieds doles" J, although the liead is so entirely different. 



Skull small and delicate. 



Dimensions of the type (as taken by the collector in the 

 Hesh) :—
