There is considerable difficulty in the unravelling 
of the synonyms and opinions regarding this spedes, 
and it is most probable that the name applied by 
Vieillot, and latterly by Lesson, must be supplanted 
by that of Ourissia. 
We give the description of the bird, figured under 
the first title. It is about three inches and a half in 
length ; the bill black, with the base of the under 
mandible yellow ; the upper parts are dull green, but 
with very brilliant reflections, approaching sometimes 
to blue, and the same colour occupies the fore part 
of the breast ; on the throat and belly the green is 
more brilliant ; the vent and under tail coverts are 
greyish ; the tail is deeply forked, of a steel blue, and 
it may be remarked, that this will be the character 
which will distinguish it from those it has been con- 
founded with. 
The female, according to Lesson, is less, and with 
all the colours duller ; the lower parts grey ; the tail 
slightly forked ; the centre feathers green, the others 
brown, tinged with blue, and the two centre ones 
tipped with white. The specimens which Lesson 
describes were sent from Porto Rico.
