BANGS: CHIRIQUI MAMMALIA. 49 



Galera barbara biologiae (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 (Lis.v.). 



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 imderstood; the name narica 

 is used here provisionally. 



Procyon lotor hernandezii (Wagler). 



One male, Pedregal, July 25. 



1 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.
