The discovery of this new and very remarkable Humming Bird is due to the researches of M. Bourcier, 

 who, during his late visit to Ecuador, obtained many new species and much valuable information respecting 

 the Trochilidse. The present is certainly not among the least important of these discoveries, the bird being 

 of large size and possessing several characters peculiar to itself; at the same time, it must be admitted that 

 its colours are not so contrasted or lustrous as those of some of its congeners. Its general contour and the 

 form of its bill and wings rendering it impossible to associate it with the members of any previously 

 established genus, and the colouring of its tail — black, interspersed with white — presenting a character 

 quite unique; I have been induced to constitute it the type of a new genus, the propriety of which must 

 be determined by time and further research, which will probably reveal to us other species of the form ; for 

 it must be recollected that our knowledge of the productions of the great primeval forests of Southern 

 America is even yet very imperfect, although each succeeding year has for some time past made us more 

 and more acquainted with them. 



Both Sir William Jardine and myself have received specimens of this bird from Professor Jameson, 

 whose researches in the forests round Quito have so frequently been attended with satisfactory results. 

 M. Bourcier's specimens were obtained in the great woods of the hot regions of Nanegan. 



Lores reddish brown ; space under the eye, forehead, all the upper surface and upper tail-coverts dark 

 coppery bronze, with a tinge of green on the greater wing-coverts, and becoming of a brighter or more 

 coppery hue on the upper tail-coverts ; wings dark purple ; two centre and the outer tail-feather on each 

 side purplish black; the remaining tail-feathers white, broadly margined externally, and very slightly fringed 

 on the apical portion of their inner webs with purplish black ; throat shining greenish blue, passing into 

 grass-green on the sides of the neck ; all the under surface dark olive, glossed with grass-green. 



The figures are the size of life. The plant is the Ceratostema longiflorum.
