Sarcorhamphus aequatorialis, Sharpe 1 — In the vivarium 

 at Central Park, New York City, I saw in December, 1878, a Condor 

 of uniform brown pbimage, which Mr. Conklin, the director of the 

 Menagerie, informed me had been received July 23, 1875, and that 

 it was three months old when captured. It was obtained on Mount 

 Cauquences, Chili, and was presented by Rear-Admiral Collins, 

 U. S. N. The fact that this example had not yet, when nearly four 

 years old, begun to assume the plumage of S. gryjyhus, proves con- 

 clusively either that the latter species retains the livery of the 

 young until four or more years of age, or that there really is, as has 

 been asserted by authors, a species of Condor among the Andes 

 which has permanently a uniform brown plumage, something like 

 that of Gyps fuhus* The locality of this specimen would extend 

 considerably the range of *S'. eequatorialis, Mr. Sharpe giving only 

 Ecuador, and doiibtfully Colombia, as the habitat of his species. 



Sarcorhamphus gryphus. The National Museum possesses 

 an adult male of this species from Bogota ; at least, the specimen 

 was in a collection received directly from that place, and shows the 

 unmistakable "make" of "Bogota" skins. This Bogota Condor 

 appears quite similar to Chilian examples in the collection, and is 

 no smaller, the wing measuring 33 inches from the carpal joint to 

 the end of the longest primary. 



* Since the above was written, Mr. Conklin has favored me with the following 

 particulars, under date of Feb. 10, 1880, in response to my inquiry as to the 

 present condition of this specimen : " The plumage remains still unchanged 

 except that the ruff about the neck is somewhat fuller, and has a little sprinkle 



of white through the down It has not increased much since then 



[July 23, 1875, the time when received at the Menagerie,] either in size or 

 weight. The bill is black at the base, the apical half ivory-white. Head bare, 

 no wattles ; iris dark brown." 



Mr. Lawrence has also favored me with the following transcript from his 

 note-book : — April 1, 1876. "Condor, said to be 9 months old, bill black ; cere 

 and naked sides of head grayish-black ; head sparsely covered with short downy 

 feathers of a smoky black ; plumage in general of a dark snuff-brown." 



August, 1877. "No change except the development of the ruft", which is 

 colored like the back." 



"The raff is now [Feb. 23, 1880] more full, but no appearance of becoming 

 white ; underneath the feathers are whitish."
