brownish, and the throat and upper breast are more tinged 

 with greenish than in the adult bird. The orange-colour 

 gradually spreads over the sides of the head from the lores 

 and region under the eyes, and is assumed not by moult 

 only, as some of my skins, as well as my observations on two 

 living specimens that I brought home with me, clearly show. 

 The bill in the adult bird is deep horn-brown, while in 

 younger specimens the upper mandible is more or less pale 

 and whitish. The sexes are quite similar.

This name was proposed by Berlepsch for the Buzzard of 

 Curasao, of which he had a single young bird, probably in 

 first plumage. Unfortunately I was unable to get an adult 

 specimen of this bird, but I obtained a young male from Herr 

 Ludwig and shot a young female on Bonaire. Both these 

 specimens are quite similar to the one that is minutely de- 

 scribed by H. v. Berlepsch, and the differences from the 

 young of Buteo albicaudatus from other countries seem to be 

 constant and well marked. I have seen the adult bird sailing 

 over and around Mt. Christoffel on Curacao, and twice on 

 Aruba, but had no chance of shooting one. The iris in the 

 young is brown, feet yellow, cere pale greenish. In the 

 stomach I found the remains of small birds, and the natives 

 on the islands say that it is very destructive to fowls. Native 

 name " Pata-lejo." The wings of my two specimens measure 

 15*1 and 15'2 inches, the tarsus 3'2. 



The adults when flying high in the air looked like the con- 

 tinental species, but will probably turn out to be distinct.
