 to add to the observations therein made. 



Genus CHRYSTTRONIA, Bonaparte (Les Chry- 

 sures, Less. ; Polytmus, in part, Gray). 



Under this genus the Prince of Canino ranges 

 four species : Ornismya jEnone, Lesson ; Ornis- 

 mya Chrysura, Lesson ; Trochilus Elicice, Bour- 

 cier ; and Trochilus Phceopygus, Lichtenstein. 



In this genus the bill is slightly recurved ; 

 the feathers of the tail are acuminated, and of 

 a brilliant red golden colour, whence Lesson's 

 term, Les Chrysures, or gold tails. The Jinone 

 is a native of Trinidad, the next two of Brazil, 

 and the fourth of Peru. 



Trochilus JEnone, Plate VII. This is a very 

 beautiful species. The head and throat are 

 intense violet; the back, chest, and shoulders 

 luminous golden green ; the tail refulgent golden 

 bronze ; wings purplish black ; bill very slightly 

 arched, the under mandible red, passing into 

 dusky black at the tip. 



Genus HELIANGELTTS, Gould (Mellisuga, in 

 part, Gray.) 



This is a gorgeous group ; distinguished by 

 the extreme lustre of the throat, which, in most 

 species, is bounded below by a gorget of white 

 or buff. All the species are natives of the 

 Andes.

 drical and very slightly depressed at the base j
