CEBUS 95 



reddish chestnut, tips of hairs pale rufous ; dorsal line darker ; shoulders 

 and front part of arms above elbows pale yellow, rest of arms to 

 middle forearm, outer side, golden yellow, grading into blackish brown 

 on lower forearm and wrist, the hairs tipped with yellowish ; hands 

 blackish ; inner side of arms dark reddish chestnut ; under parts chest- 

 nut becoming blackish towards groin ; tail blackish brown, hairs tipped 

 with grayish. 



Measurements. Total length about 980 ; tail, 525. Skull in speci- 

 men. 



There are two examples of this form in the Paris Museum and 

 each one marked "un des types," but the real type, unless one of the 

 specimens is it, does not seem to be in the collection. Both examples 

 came from Cayenne, onebroughtbyM. Martin in 1819, the other by M. 

 Poiteau in 1882. I am not satisfied to consider these as C. apella, 

 (capucinus Auct.), for besides the peculiar chestnut color of the body, 

 and the yellow on shoulders and upper arm, the head lacks entirely 

 the black cap of apella and the black lines on side of face meeting 

 under the chin. There are no tufts and the hair on head is short.
