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 

 Chili t, Peru, New Granada (Antioquia), Veragua, 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 % i 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 w ith 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 Veragua, in the collection of Messrs. Salvin 

 and Godmau : — The entire mantle is dark chocolate-brown, 

 but with most of the feathers narrowly edged with rufous ; 

 the greater wiug-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 Norwch Museum has 

 a crest 3-75 inches in length, whilst, so far as I have observed, the cor- 

 responding occipital feathers in //. 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 IT. solitarius. 



X This chocolate tint probably indicates a remaining ti-ace of im- 

 maturity.
