This lovely species seems to have been first no- 
ticed and described by Mr Swainson ; consequently 
we have given his name at the head of this descrip- 
tion, in preference to that of Lesson, which is en- 
graved upon the Plate. The first specimens seem 
to have formed part of the collection of the Duke Ri- 
voli in Paris, and several individuals have since been 
brought to this country. It is a native of Mexico. 
It is a bird of a very slender form ; the upper parts 
are bright yellowish green, the under nearly pure 
white, tinged with greenish on the flanks, and the 
throat and fore part of the neck are covered with 
beautiful lengthened plumes of a bluish violet colour, 
assuming a pink or ultramarine tint according to the 
position. The tail is deeply forked, and the outer 
feathers become narrow towards the tips. The fe- 
male has not yet been described.
