Thomas says of these names (/. c.): " It is difficult to know 

 how to deal with Martin's Cercoleptes megalotus and brachyotus, 

 described from menagerie specimens without localities, . . . 

 the characters used being mainly due, according to Gray, to the 

 'artifice of the preserver.' ... In any event the name 

 [brachyotus] may be put aside for the present as indetermin- 

 able." The other he adopts for a deep-colored form from 

 "Costa Rica and Colombia," mentioning an example from 

 Medellin, Colombia, as agreeing "best with the description," 

 and cites others from Costa Rica, and from Valdivia and 

 Santa Marta, Colombia, which "cannot be distinguished from 

 it." The five subspecies he recognized may be tabulated as 

 follows : 



Potos flavus flavus. Guiana. 



Potos flavus megalotus. Costa Rica and Colombia. 



Potos flavus aztecus. Mexico and Guatemala. 



Potos flavus ntodestus. Guayas Province, Western Ecuador. 



Potos flavus meridensis. Sierra Nevada, Merida, Venezuela. 



Nothing is said about the range of flavus (typica) further 

 than to consider "Surinam" as the type locality. 



This Museum contains a series of 23 specimens of Kinkajous, 

 of which i (without skull) is from Merida, Venezuela (topotype 

 of P. f. meridensis); 7 from Santa Marta, Colombia; 4 from 

 Castilla Mountains, Colombia (upper Cauca region); 4 from 

 Chiriqui, Panama; i from Chapada, Matto Grosso, Brazil; 

 and 6 menagerie specimens, without localities, and hence 

 practically worthless. Mr. Bangs has kindly loaned me 6 

 others 3 from Orizaba, Mexico, and 3 from Chiriqui. 



The material from these six localities Orizaba, Chiriqui, 

 Merida, the Castilla Mountains, Santa Marta, and Chapada 

 represent six well-marked forms, three of which appear to 

 be unnamed. The Merida specimen is, of course, Thomas's 

 Potos flavus meridensis. The Chiriqui specimens are very 

 different from the Santa Marta specimens and must be sepa- 

 rated from them ; and in this connection comes up the difficult 

 question of deciding on names for them, a matter which has
