It is about five inclies in lengtli, of which the tail 
makes up three. The upper parts of tlie 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 and 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 
head 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.
