Mr. R, B. Sharpens Catalogue of Acclpitrcs. 331 



feathers of the black cap, which extends from above the eyes 

 to the nape, are tipped with pale fulvous, with which colour 

 the upper nuchal collar (white in the adult) is also tinge 

 all the feathers of the mantle are more or less distinctly 

 tipped with rufous brown, which is brightest and widest on 

 the hinder tertials, where it takes the place of the whit tips 

 so conspicuous on those feathers in the adult bird ; the rec- 

 trices are narrowly tipped with white, the breast, abdomen, 

 and under wing-coverts being strongly tinged with rufescent 

 fulvous. 



As Mr. Sharpe does not mention the colour of the iris in 

 this species, I may here note that an adult, or nearly adult, 

 male, described in Leotaud's ' Oiseaux de la Trinidad, pp. 41 

 & 42, is there said to have had "cire, iris, et pattes jaunes.''^ 



I may add that the Norwich Museum possesses a specimen 

 of G. swainsoni ft'om Sta. Marta, Colombia, which is a more 

 western locality than any o£ those quoted for this species by 

 Mr. Sharpe*. 



In referring next to the genus Elanus, I may observe that 

 Mr. Sharpe, in his " Key to the Species " of that genus, 

 applies the terms '' inner lining of wing '^ and " wing-lining " 

 to the under surface of the primaries ; and I think it desirable, 

 for the sake of guarding against any possible misapprehension, 

 to mention that where I have used the phrase " wing-lining," 

 I have not used it in the same sense as that in which Mr. 

 Sharpe has, in this passage, applied it, but as designating the 

 under wing-coverts, which seem to me to be the part of the 

 wing to which the term "lining " most properly aj)pliest- 



Mr. Sharpe, very properly, as it seems to me, does not 

 admit E. minor of Bonaparte as specifically, or even subspe- 

 cifically, distinct from E. cceruleus ; and though variations of 



* Anotlier westerly locality for this species is Tumbez, in North- 

 western Peru (vide P. Z. S. 1877, p. 744.). 



t The term " lining of the wing " is applied to the under wiug-coverta 

 in the article on the genus Elanus in Messi's. Baird, Brewer, and Ridg- 

 way's 'History of North- American Birds,' vol. iii. p. 197. On the other 

 hand, Mr. Dresser, va. his article on E. cceruleus in the * Birds of Europe/ 

 speaks of the " wiug-lining " in the same sense as that in which the words 

 are used by Mr. Sharpe.
