It will be seen that I have followed preceding ornithologists in considering the Trochilus lazulus of 

 Vieillot's '' Galerie des Oiseaux," and the Tfalcatus of Swainson's "Zoological Illustrations," as identical; 

 at the same time I must remark, that neither of their figures nor the accompanying descriptions are 

 quite correct ; Vieillot figuring and describing the under tail-coverts as white, and Swainson as green, 

 whereas these feathers are really deep chestnut ; with this exception the two figures agree with the bird 

 here represented. 



It is just possible that the bird described by these authors, and which is still in the Paris Museum, may 

 be different from the one I have figured, but, if it be, surely additional examples would have reached Europe 

 during the long interval which has elapsed since the dispersion of Bullock's collection, of which the Paris 

 specimen formed a part. 



The native habitat of this fine species — for it is a truly beautiful bird — is the Caraccas, Venezuela, and the 

 high parts of Columbia generally : many fine examples were brought from the former country by Mr, Dyson, 

 and numerous specimens are from time to time received in collections from Bogota. As will be seen on 

 reference to the accompanying Plate, the sexes differ materially in their colouring : the young males, again, 

 diflfer from both in presenting an intermediate kind of plumage, with more or less blue on the throat and 

 under surface. 



The male has the head, all the upper surface, wing- and tail-coverts glittering grass-green ; wings 

 purplish brown ; tail very deep chestnut, with in some instances all the feathers, and in others only the two 

 middle ones, broadly tipped with deep green ; throat rich deep shining blue, blending into the green of the 

 upper surface, and the finer glittering green of the flanks and abdomen; under tail-coverts chestnut, slightly 

 tipped in some instances with green ; bill black. 



The female has all the upper surface and wing-coverts bronzy green ; rump and upper tail-coverts purer 

 green ; wings purplish brown ; central tail-feathers bronzy green ; the remainder deep chestnut, more or 

 less margined or fringed with black ; under surface, including the under tail-coverts, deep brownish grey. 



The figures are the size of life. The plant is the Cat tleyia guttata.
