I have much pleasure in adding the following note contained in a letter from my friend, received since my arrival in England. Mr. Hill, having made some inquiries of a gentleman residing among the Blue Mountains, Andrew G. Johnston, Esq., received the following reply:—“I have no copy of my musical score of the Solitaire’s song. The bird _now_ [July 27th] uses only its long breve notes [Music] and its octave, often out of tune, more often so than perfect. In the spring they are very numerous in the deep forests, and warble very prettily, somewhat like this:— [Music] sometimes thus— [Music] The pointed crotchets are very sweet sounds, and seem to sound [symbol]E—vil [symbol]evil. I tried in vain to get one this spring, but I find the negroes know nothing about them. Hearing them one day singing, I asked two maroon-men who also listened, what birds they were. One said _a grey speckled bird, mottled like a guinea-fowl_: the other that it was black, and red about the rump and under the wings.” My conjectures on both points, are thus confirmed. I may add that the most common notes that I have heard are these. [Music: _tr_ _tr_] Vieillot, who first described the species by the name of _Muscicapa armillata_, says that “it inhabits the Antilles, but is very rare in the greater islands.” His figure, pl. 42, is poor, both as regards form and colour. Mr. Swainson’s figure of _Myiadestes genibarbis_, (Nat. Lib. Flycatchers, pl. 13,) _if meant_ for this species, is better as to colouring, but neither its form nor attitude is correct. Moreover, as he says, its body is not much larger than that of the robin, and mentions white lines on the black ear-coverts, it is with me a matter of doubt; especially as he speaks of the intimate resemblance which it bears to our common robin, “not merely in the red colour of the throat,” but in form; a resemblance certainly not discoverable in the living bird. The figure in Mr. Gray’s Genera of Birds was drawn from one of the specimens procured by me in Jamaica, and is in winter plumage. +Fam.+—CORVIDÆ.—(_The Crows._) BLACK-HEADED JAY.[58] _Cyanocorax pileatus._ _Corvus pileatus_, +Ill.+—Pl. col. 58.
