NO. 5 MAMMALS OF PANAMA — GOLDMAN 157 



of the Chagres River near Gatun one of these animals was located 

 by the glare of its eyes in a tree top. When it was shot and dropped 

 to the ground short muffled squeaking sounds and rustling branches 

 were heard as several others, assumed to be of the same species, 

 climbed rapidly away through the trees. The stomach of the example 

 taken contained a small quantity of the pulp of some unidentifiable 

 fruit. Several native hunters readily identified the specimen as an 

 olingo, a name they apply also to Potos, and I found that they made 

 no distinction between the two animals. 



Specimens examined: Near Gatun, I ; Corozal, I. 



BASSARICYON GABBII ORINOMUS Goldman 



Panama Bushy-tailed Olingo 



[Plate 34, figs, i, la] 



Bassariscyon [sic] gabbi orinomus Goldman, Smiths. Misc. Coll., Vol. 6o, 

 No. 2, pp. 16-17, September 20, 1912. Type from Cana, eastern Panama 

 (altitude 1,800 feet). 



The form of Bassaricyon gabbii inhabiting the mountains of 

 eastern Panama differs from typical B. g. gabbii of Costa Rica, 

 western Panama and the Canal Zone in more tawny or paler fulvous, 

 less brownish, coloration. It differs also in combination of cranial 

 characters, the basioccipital being broader, the postorbital processes 

 longer, more projecting, and the audital bullae decidedly smaller. 



It was met with on several occasions while hunting at night in the 

 forest at about 2,000 feet near Cana, always among the upper 

 branches of trees, its eyes appearing in the narrow field of light 

 projected by the acetylene gas burner like those of Potos. In fact 

 I rarely knew what animal I fired at until it came tumbling to the 

 ground. The eyes are of course visible only when the animal has an 

 unobstructed view toward the hunter, and unless a quick and effective 

 shot is fired the game is apt to be lost. Like Potos these animals 

 climb about in small parties ; two were shot in the same tree and 

 several others were heard making off. On one occasion a Bassari- 

 cyon was killed and another shot fired a moment later at a pair of 

 eyes in the same tree brought down an example of Potos. Both 

 species had, as the contents of their stomachs showed, been attracted 

 by the ripening fruit in the top of the tree, a tall species unknown to 

 me. A Bassaricyon shot at 5,000 feet near the summit of Mount 

 Pirre was in the act of passing from the top of one tall tree to 

 another. 



Specimens examined : Cana, 5 ; Mount Pirre, 1.
