Mr. R. B. Sharpe’s Catalogue of Accipitres. 475 
specimen of L. melanops also differs from the adult in having 
two white transverse bars on the tail besides the white tip; 
the lower bar of the two measures *7 of an inch in width, the 
upper bar, which is less perfect, is somewhat narrower. 
In this specimen all the under surface is white, slightly 
tinged with buff, and the white portions of the plumage of 
the head and neck are also similarly tinted. 
Mr. Bidgway, in his description of the adult of this species 
(‘ Studies of the American Falconidse/ p. 177), says that these 
parts sometimes exhibit “ a beautiful salmon-pink tinge, espe¬ 
cially under the wing.” 
I am happy to learn that the very fine series of Buzzards of 
the genus Leucopternis possessed by Messrs. Salvin and God- 
man has very recently been enriched by an additional speci¬ 
men of each of those very rare species L. plumbea and L. 
semiplumbea , both obtained from Yeragua. Mr. Salvin, 
writing to me respecting this specimen of L. semiplumbea , 
adds the following information, which, by his permission, I 
here transcribe : it “ seems to be a younger bird than I have 
yet seen of this species; the colour of the upper surface is 
darker and not so clear plumbeous; there are some well- 
defined longitudinal streaks on the upper breast; the central 
tail-feathers have two instead of a single band; and the wings 
are more strongly barred beneath at their extremities.” Two 
other specimens of L. semiplumbea have also been recently 
added to the same collection, from the province of Antioquia, 
in the United States of Columbia, a new and more southern 
locality for this species*. 
With regard to the remaining species of the genus Leuco- 
pternis , I have nothing to add to the information contained 
in Mr. Sharpe's volume f; I therefore pass on to the consi- 
* In one of the specimens of L. semiplumbea in the collection of Messrs. 
Salvin and Godman the upper white caudal band, indicative of imma¬ 
turity, has entirely disappeared, with the exception of a single small white 
spot still remaining on one of the central rectrices; the white bars on the 
tail of immature birds of this species are of a less clear white than on 
those of the adult. 
t Since the above was written I have had an opportunity of examining 
the very interesting and apparently distinct new Leucoptemis, lately ob-
