In JS'ov. 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. n. 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 S.E. Peru and Bolivia are certainly very much like 

 C. a. inti'rmediu.'i, and the females agree with the Orinoco ones in having the throat 

 unspotted deep orange ; but the pileum is decidedly paler, sulphur-yellow, withont 

 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 Bogota. 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. Pern, 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 diti'ereut.
