 Trochilus Nuna LESSON. 



La Nouna-Koali, Ornismya Nuna, Lesson, Histoire Xatur- 

 elle des Oiseaux-mouches, Supplement, pi. xxxv. 



IT is about five inches in length, of which the tail 

 makes up three. The upper parts of the plumage 

 are of a brilliant emerald-green, with golden reflec- 

 tions. The under parts are pure white ; but each 

 feather has at its tip a circular spot or eye, of a deep 

 emerald-green, which forms a fine contrast. On the 

 throat and breast, these are well arid distinctly marked, 

 but towards the vent they become less defined. The 

 under coverts of the tail are bright chestnut. The 

 tail itself has the feathers very broad, and they gra- 

 dually increase in length like those of the bar-tailed 

 species. The base of all the middle ones are brown- 

 ish purple. The lower part of the exposed portion 

 on the upper side is of a deep steel-blue, changing 

 to a bright and beautiful green towards the tip. The 

 outer feathers have the exposed parts of the tips 

 deep steel-blue; but the lower half of the outer web 

 is pure white. In another specimen, which M. Les- 

 son supposes to be the young, the crown of the 

 hwul is almost grey, and the long outer feathers 

 of the tail want the white outer edge, and are en- 

 tirely brown, and the under plumage was dashed 

 with brownish red. 



These specimens come from Peru.
