NO. 5 MAMMALS OF PANAMA GOLDMAN 1 59 



(altitude 2,650 to 5,200 feet). Concerning them, he says: "Two 

 were taken from a hollow tree at Tacarcuna, two were shot by moon- 

 light and with the jack light at the upper camp on Tacarcuna, and 

 others were secured from the natives. At the upper camp this species 

 came nightly to feed on what seemed to be a variety of wild fig, a 

 fruit about' the size of a man's thumb, with a pink center. Shortly 

 after sun down, a small band of probably eight to a dozen individuals 

 would be heard coming into the fruit trees. They travelled entirely 

 through the trees and did not descend to the ground. Quantities of 

 dead twigs and debris were shaken down by their weight, and their 

 progress could be thus noted when the moving branches could not 

 be seen. 



" The eyes of the Kinkajou (' Cusumbi ' or ' Manteja,' native 

 names) shine strongly red under the jack light. One was eaten and 

 its flesh proved to be quite palatable. A nasal, grunting sound was 

 the only call heard." 



Specimens examined: Cana, 4; Mount Pirre (type locality), 4; 

 Tacarcuna, 4 * ; Tapalisa, 3. 1 



POTOS FLAVUS CHIRIQUENSIS Allen 



Chiriqui Kinkajou; Olingo 



Potos Uavus chiriquensis Allen, Bull. Amer. Mus. Nat. Hist., Vol. 20, p. 72, 

 February 29, 1904. Type from Boqueron, Chiriqui, Panama. 



The Chiriqui kinkajou inhabits the western part of the republic 

 and ranges as far east at least as the Canal Zone. It is replaced in 

 eastern Panama by P. f. isthmicus which is distinguished by the 

 possession of a distinct black dorsal stripe and a different combina- 

 tion of cranial characters, especially the narrower interorbital region 

 and stouter more gradually tapering, less peg-like postorbital proc- 

 esses. The striking general resemblance of the species of Potos to 

 those of Bassaricyon has been mentioned in the remarks on the genus. 



A series of specimens from the vicinity of Gatun includes adults 

 and young of both sexes showing a wide range of variation in the 

 intensity of the general yellowish tawny color. A trace of the dark 

 median dorsal stripe, which is more distinct in Potos Uavus isthmicus, 

 seems to indicate gradation toward that form. 



The Chiriqui kinkajou seems to be one of the more common 

 mammals of the region, but owing to nocturnal habits it is little 

 known. Examples were obtained by shooting them from trees in the 

 heavy forest where by the light of a hunting lamp their eyes were
