This form of the Woolly Philander differs by its bright 

 rufous colour from the dark C. I. ci'cur, Bangs, of Sta. Marta, 

 Bogotd, and the Oriente of Ecuador^ on the one hand, and 

 from the peculiar pale (juayanus of S.W. Ecuador on the 

 other. Its light forearms and hands also distinguish it from 

 the former, as from the Amazonian ocliropus^ Wagn., and the 

 Peruvian ornatus^ Tschudi. Perhaps it is really most allied 

 to the Central-American derbianus, Waterh., but differs by 

 the reduction of the white dorsal patch to a mere trace, the 

 more defined frontal stripe, and the much darker colour of the 

 woolly part of the tail. The unusually slight difference in 

 the extension of the upper and lower fur on the tail is also a 

 well-marked character common to all the specimens examined. 



The Ecuadorean specimens are like that from Colombia in 

 every respect.
