seen flashing among the branches. They hunt in small parties and 

 several may sometimes be killed in a single tree. When approached 

 a short, rather hoarse barking sound is sometimes given and a 

 rustling noise may be heard as they climb or leap from branch to 

 branch. Several kinds of wild fruits were found in the stomachs 

 examined, including a common leguminous species known as 

 " guava." Fruit seems to be their principal diet, but they doubtless 

 feed on many other things. One partially filled stomach contained 

 mainly fragments of large insects, but included small Coleopterous 

 species swallowed entire. These kinkajous are easily tamed and 

 often kept as pets, although they are inactive and remain curled up in 

 a corner during the day, and are inclined to be mischievous at night. 

 A rather young individual, which had recently been caught in the 

 forest, climbed to my shoulder and sat with its long tail coiled about 

 my neck. 



Bangs (1902, p. 49) listed specimens collected by W. W. Brown, 

 Jr., at Bogava and remarks : " I do not think the Central American 

 form is the same as true P. caudivolvulus of Surinam, but I have 

 not sufficient material to decide the question." Under the name 

 Potos fiavus megalotis, Thomas (1903a, p. 40) recorded specimens 

 probably referable to P. f. chiriquensis from Parida, Sevilla, and 

 Almijas, all small islands near the southern coast of western Panama. 



The name applied to the animal by natives of the Canal Zone is 

 " olingo." 



Specimens examined: Boqueron, 6 1 ; Bogava, 3 2 ; Gatun, 15. 



Family MUSTELIDAE. Weasels, Tayras, Grisons, Skunks, 



Otters, etc. 



The family, as restricted within our limits, includes a weasel of 

 the familiar type, the tayra and grison, large powerful weasel-like 

 animals, a long-nosed skunk, and an otter. 



Subfamily MUSTELINAE. Weasels 

 Genus MUSTELA Linnaeus. Weasels 

 The weasels, mainly boreal in distribution, are represented in the 

 region by a single form which ranges well into South America. Its 

 small size, elongated body, short limbs, and hairy soles of hind feet 

 distinguish it from the other carnivores of the region. The white 

 facial markings present in the northern forms are absent or barely 

 indicated by a few white hairs in front of the ears.
