Our plate is engraved from the representation of 
Lesson, which is made from the only known specimen, 
in possession of M. Dupont, to whom the species has 
been dedicated. 
It is a native of Mexico, has a sharp and pointed 
bill, a lengthened tail, and a form comparatively 
slender. The total length is about four inches and a 
quarter, inclusive of the bill and tail. The upper 
part of the plumage is of a shining yellowish green, 
crossed upon the lower part of the back by a white 
band ; a patch of black, or dark blue, according to 
the light in which it is viewed, covers the throat, 
cheeks, and middle of the neck. The flanks and 
belly are a light brownish green, passing into pure 
white on the vent. The wings are rather short, nar- 
row, and falciform, of a brownish purple. The tail 
is remarkable for the form of the exterior feathers.
