resembling the dress of the adult female, and the third that 

 which Mr. Sharpe correctly designates as the plumage of the 

 " adult male/' 



Mr. Sharpe includes Buteo varius of Gould amongst the 

 synonyms of B. erythronotus — which I am able to confirm, 

 as the type specimen is now in the Norwich Museum, and is 

 an immature example of this species. 



There is also included amongst the synonyms of B. ery- 

 thronotus in Mr. Sharpens work Buteo unicolor of D'Orbigny ; 

 but this I am convinced is a mistake, as the Buzzard de- 

 scribed by D'Orbigny under that name is decidedly smaller 

 than B. erythronotus, and very differently coloured. 



In the list given by Mr. Sharpe of the specimens of B. ery- 

 thronotus preserved in the British Museum, there is included 

 an immature skin from the island of Masafuera, that should 

 no doubt be referred to the very interesting allied species 

 Buteo exsul, which has only been obtained on that island, and 

 which, subsequently to the publication of Mr. Sharpens vol- 

 ume, has been described by Mr. Salvin at page 371 of The 

 Ibis' for 1875. 



Messrs. Salvin and Godman have very kindly permitted me 

 to examine their specimens of this fine Buzzard ; and I have 

 thus been enabled to observe that the white margins to the 

 lesser wing-coverts and interscapulary feathers are broader 

 and more numerous in the adult female than in the adult male ; 

 but, beyond this remark, I have nothing to add to the full 

 description which Mr. Salvin has already published, except to 

 note that in this species the fourth primary is but very 

 slightly emarginated. 



Another species closely allied to Buteo erythronotus is Buteo 

 poliosomus. The first plumage of this Buzzard is not described 

 in Mr. Sharpe's work ; and I therefore propose to give some 

 particulars respecting it, taken from three specimens in that 

 stage obtained in the Falkland Islands, and now preserved 

 in the Norwich Museum. These bear a general resemblance 

 to the corresponding plumage of B. erythronotus, but are 

 much more fuliginous in the tone of their colouring. On 

 their upper surface the scapulars, interscapulars, and wing-
