Sir William Jardine received a specimen of this very curious 
and beautiful bird in September 1859 from Professor Jameson 
of Quito, and described it in the { Edinburgh New Philosophical 
Journal’ for that year, as noticed above. In the following volume 
some further details were given respecting it, and an uncoloured 
drawing of it, from the pencil of Mrs. H. E. Strickland. Sir 
William Jardine having kindly placed the stone with the drawing 
on it at my disposal, I thought that a coloured figure of this 
strange bird would be acceptable to the readers of ‘The,Ibis/ 
and I have to thank Mrs. Strickland for supplying me with a 
coloured copy of the plate for a pattern. 
Sir William Jardine has since received a second example of 
this bird from Professor Jameson. I particularly called the 
attention of Mr. Eraser, when he was in Ecuador, to this bird; 
but though he visited the exact locality where Professor Jameson’s 
specimens were obtained (Nanegal, on the Pacific slope of the 
western range of the Andes, as he was informed by Professor 
Jameson, and not Cayambe), he was unable to procure specimens; 
so we must suppose the bird to be rare. 
will be found collected in Horsfield and Moore’s f Catalogue of the Birds 
in the East India Company’s Museum’ (ii. p. 635 et seq.).
