This species has some characters in common with the one I have called Eucephalas maragdo-c&ridea, but it 

 differs from that bird in several particulars of sufficient importance to warrant its being regarded as distinct : 

 in the first place, there is no blue whatever on the chin and upper part of the breast, those parts being 

 clear green like the remainder of the under surface ; in the next, the under tail-coverts are white with a 

 stain of olive-brown in the centre of each feather, while the same feathers in the E. smaragdo-ccerulea are 

 green ; and lastly, the upper tail-coverts are bronzy brown in the present bird, and bright green, even 

 brighter than that of the back, in the other. 



The Eucephala chlorocephala is a very rare bird, and its native country is I believe at present unknown ; 

 for although M. Bourcier states that it flies in the environs of Guaranda in Ecuador, I think that gentleman 

 must have been misinformed on this point, and that in all probability the bird inhabits Brazil ; but of this I 



am of course uncertain. 



Of its habits and economy nothing has been recorded ; nor is it even known whether any difference 



occurs in the outward appearance of the two sexes. 



Crown of the head bluish grass-green ; all the upper surface and wing-coverts bronzy green ; wings 

 purplish brown ; upper tail-coverts rich coppery bronze ; tail uniform dark steel-blue ; chin, throat, and 

 abdomen shining grass-green ; thighs white ; under tail-coverts dark olive broadly margined with white ; 

 bill black ; base of the under mandible fleshy. 



The figures are of the natural size. The plant is the Sciodacalyx Warszewiezii.
