.NO. 5 MAMMALS OF PANAMA — GOLDMAN 23 I 



The tail is long and curled under, but not naked near the tip. One 

 species, represented by two subspecies, inhabits Panama. 



CEBUS CAPUCINUS CAPUCINUS (Linnaeus) 

 Culombian VVhite-tliroalcd Capuchin 

 S[iiiiia\ capuiiua Linn^t^us, Syst. Nat., ed. 10, Vol. i, p. 29, 1758. Type 

 reyioii nortlicrn Colombia.' 



The capuchins arc recognizable by the extensive white area cover- 

 ing the entire face, sides of neck, throat, chest, and shoulders, in 

 marked contrast with the glossy black remaining parts of the body. 

 C. capiicimis of recent authors is the animal which formerly was 

 commonly referred to C. hypolettcus (Humboldt). The type locality 

 of the latter is Rio Sinu, Colombia, and as the two are now regarded 

 as identical the animal inhabiting eastern Panama and ranging as 

 far southward as Paramba, Ecuador, is probably typical. In the 

 vicinity of the Canal Zone C. capuciniis capucinus is replaced by a 

 northern geographic race, C. c. imitator, which is distinguished by 

 the greater transverse extent of the premolars. 



The white-throated capuchin was met with on several occasions, 

 in the forests of eastern Panama, at localities ranging from i,ooo to 

 5,000 feet altitude. On Cerro Azul, near the headwaters of the 

 Chagres River, a troop of eight or ten of these monkeys was found 

 in the tops of tall trees on a steep hillside. When two were shot the 

 others gave short cries of alarm and scampered off through the tree 

 tops, showing great activity, but their progress seemed slower than 

 that of Ateles'gcoffroyi under similar circumstances and I saw none 

 of the tremendous flying leaps by which the latter species spans 

 the distance between trees standing well apart. In the excessively 

 humid forest covering the Atlantic slope of Cerro Bruj(; a small 

 troop in the tops of tall trees remained quietly watching my party 

 passing beneath. On Mount Pirre a lone male was heard giving 

 hoarse barking sounds as he climbed rather slowly through the tojj 

 of a tall tree in the heavy forest at 5,000 feet. The white area was 

 conspicuous as he paused for a moment and looked down. Lionel 

 Wafer (1729, p. 330) doubtless referred in part to this species when 

 in describing the animals of eastern Panama he says : " There are 

 great Droves of Monkeys, some of them white." Anthony (1916, 

 p. 375) records si)ecimens from Chepigana, Real de Santa Maria, 

 and Tacarcuna (altitude 3,000 to 5,000 feet). 



Specimens examined: Cerro Azul, 2; Cerro Brujo, 2; Chepigana, 

 I ' ; Mount Pirre, 3 ; Real de Santa Maria, 2 ' ; Tacarcuna, 6.'
