Distribution. — Southern Costa Rica, western Panama to near the 

 Colombian boundary; doubtless reaching Colombia, but range in that 

 country undetermined. Tropical Zone. 



General characters. — A dark Panama representative of the species 

 ranging widely in South America. Similar in size to P. c. proteus of 

 northern Colombia, but general color less tawny; cranial details dis- 

 tinctive. Differing from P. c. cancrivorus, of Cayenne, in darker color 

 and in cranial characters. 



Color. — Ground color over dorsum varying from ashy gray to ochra- 

 ceous buffy or yellowish ochraceous, heavily overlaid with black; top 

 of head grizzled black and gray, the black predominating; sides of 

 muzzle, and rather restricted supraorbital streaks, white or grayish 

 white; facial area, including orbits, interorbital space, lower part of 

 cheeks, and median line from forehead to nose, nearly clear black; 

 under parts, including base of tail, varying from pale ochraceous buff 

 to yellowish ochraceous, becoming more or less grayish white on throat, 

 chin, and lips; ears well-clothed with whitish or j^ellowish hairs, dark- 

 ening gradually on upper base by encroachment of body color; outer 

 sides of hind legs and ankles all around deep glossy black; fore legs 

 black or dark brownish all around; feet thinly clothed with short hairs 

 varying from brownish to grayish ; tail with seven or eight alternating 

 black and grayish or yellowish rings and a black tip, the proximal rings 

 more or less interrupted along median line below.

 cipital more convex, the lateral margins turning downward and partly 

 covering auditory bullae; nasals broader; auditory bullae broader, 

 more inflated posteriorly; dentition about the same. Contrasted with
