bare and slightly protruding eyelid, which, in its allies, is black, beset with 
numerous white plumules, ]

In Nov. Zool. xiv. 1907. p. 82 I have given a short review of the geographical 
races of C. auratus. Alluding to the singular distribution of C. a. intermedius, 
I said that I could not distinguish Marcapata and Bolivian specimens from the 
typical Orinoco birds. Since writing this I have had the opportunity of studying 
the series in Count Berlepsch’s Museum, and find that this statement requires 
modification. Specimens from 8.E. Pera and Bolivia are certainly very much like 
C. a. intermedius, and the females agree with the Orinoco ones in having the throat 
unspotted deep orange ; but the pileum is decidedly paler, sulpbur-yellow, without 
any orange admixture. The three skins from Calama are identical with the 
Marcapata series except for the ground-colour of the throat being clear orange, 
as in C. a. auratus from Northern Peru, Ecuador, and Bogoté. The throat, in the 
females, is, however, entirely unspotted. Though I feel pretty sure that the 
birds from the Rio Madeira, N. Bolivia, and Marcapata, S.E. Pera, constitute 
a recognizable race, I prefer to await further material before proposing any formal 
separation, inasmuch as those from the first-named locality may again be different.
