much more darkly coloured, with a shorter crest *, and in their 
very distinct geographical distribution— H. coronatus being 
found in Patagonia, and thence northwards to Bolivia and 
Southern Brazil, whilst H. solitarius has been obtained in 
Chilif, Peru, New Granada (Antioquia), Yeragua, Guatemala 
(San Geronimo), and probably also Southern Mexico, as a 
Central-American specimen in the Norwich Museum is be¬ 
lieved to have been obtained in that country: this example 
is very nearly adult; and I add the following particulars 
respecting it, as Mr. Sharpe gives no description of this 
species :—The general colouring throughout is bluish black, 
shaded with chocolate J ; the quill feathers of the wing are 
blackish, but the secondaries are tinged and mottled with 
grey, except at the tips, which are black; the upper tail- 
coverts are tipped with white; the tail is black, tipped with 
white, and has a broad white median band and traces of an 
imperfect basal band, which is also white. 
The following is a description of a specimen in immature 
plumage, from Yeragua, in the collection of Messrs. Salvin 
and Godman:—The entire mantle is dark chocolate-brown, 
but with most of the feathers narrowly edged with rufous; 
the greater wing-coverts are much mottled with rufous, espe¬ 
cially the inner webs of the coverts overlapping the secon¬ 
daries, which, together with the tertials, are also tipped with 
rufous; the secondaries and the tertials resemble the greater 
wing-coverts, but the secondaries are somewhat more rufous; 
the primaries are dark, becoming black towards the tips, but 
with the base of the inner webs white, spotted with dark 
brown; the upper tail-coverts are rufescent fulvous, with 
large shaft-marks of dark chocolate brown; the rectrices, 
* A nearly adult female of H. coronatus in the Norwich Museum has 
a crest 3*75 inches in length, whilst, so far as I have observed, the cor¬ 
responding occipital feathers in H. solitarius do not, at most, exceed the 
length of about two inches. 
t The specimen in the British Museum entered in Mr. Sharpe’s work 
under the head of H. coronatus, “ c. Var. st. Chili,” is a nearly adult ex¬ 
ample of II. solitarius. 
t This chocolate tint probably indicates a remaining trace of im¬ 
maturity.
