tail entirely black, instead of its being " grey with a broad 

 terminal band of black," as described by Mr. Sliarpe, in 

 which particular it seems to agree with Temminck's figure in 

 the Planches Coloriees, pi. 61. 



The description contained in the letterpress which accom- 

 panies Temminck's plate evidently refers to another species, 

 probably to R. sociabilis = leucopygus, as it states that " la base 

 de la queue et les couvertures de dessous sont blanchatres.^' 



The specimen figured by Temminck was in the Leydcn 

 Museum'^, and apparently agreed with the example of the 

 whole-coloured species described under the name of Buteo 

 hamatus of Illiger, from a Brazilian specimen in the collec- 

 tion of Baron Laugier, in vol. iii. p. 1223 of the ' Tableau 

 Encyclopedique et Methodique' of Bonnaterre and Vieillot, 

 published in 1823. This was also the year of the publication 

 of the part of Temminck's and Laugier's 'Planches Coloriees' 

 that contained the figure above referred to. 



I have taken the following measurements (in inches and 

 tenths) from the specimen of R. hamatus in the collection of 

 Messrs. Salvin and Godman : —

Messrs. Baird, Brewer, and Ridgeway (/. c.) appear to refer 

 to R. hamatus sl specimen brought from the Amazons by Lieut. 

 Hemdon, which differs from Messrs. Salvin and Godraan's 

 example, and also from Temminck's figure, in having the 

 " tail perfectly even, with an obscurely indicated narrow in-

 published in the first livraison of his work, in which he says, " Pour eviter 

 en chaque article des repetitious iuutiles, on est prevenu que la premiere

 modele a nos 'Planches Colorizes."
