BANGS: CHIRIQUI MAMMALIA. 49 
Galera barbara biologiz (THomas). 
One male, Bogaba, July 9. The black-headed Central American form is a 
very strongly marked subspecies; in addition to this specimen the Museum has 
skins from Costa Rica collected by Gabb. 
Putorius (Ictis) affinis (Gray). 
Three specimens, two adult and one young males, Boquete, 4,000 to 5,800 
feet, February, March, and April. These examples agree very well with Gray’s 
description ; they vary somewhat among themselves in color ; the young one, 
No. 10,114, has a wholly black head, the other two have small irregular (not 
the same on both sides) white patches, behind the eye, in front of the ear, 
and above the corner of the mouth. In No. 10,114, the under parts, except 
the chin, which is whitish in all three, are intense orange-rufous; in No. 
10,112, the under parts are a paler shade of the same color; and in No. 10,113 
paler still and more yellowish.

Potos caudivolvulus (Scur.). 
Three specimens, two males and a 9, Bogaba, July. 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. 
Nasua narica (Linv.). 
Six specimens, both sexes, Boquete, 3,800 to 5,800 feet, April and March. 
The nasuas separate naturally into many geographic races. These, as proper 
material accumulates, are gradually coming to be understood; the name narica 
is used here provisionally. 
Procyon lotor hernandezii (Wacrer). 
One male, Pedregal, July 25. 
‘ I suspect this specimen was wrongly sexed, and is an adult 9; judged by the 
skull it is not much younger than No. 10,112.
