primaries. The first quill is scarcely more than two-thirds the fourth, (which is longest,) both 
measured from the carpal joint. It is more than an inch shorter than the second, which, in 
urn, is half an inch shorter than the third. The tail is long, hut, in the specimen before 
me, too much mutilated to furnish a satisfactory description. 
The body generally is green, with a yellowish or, perhaps, fulvous shade, especially on the 
anterior half of the body. The lower parts are rather paler. The wings and tail are of a 
purer green ; the outer webs of the primaries and the ends of the tail feathers with a bluish 
shade. The top of the head, with the short occipital crest, are bright blue, most vivid poste¬ 
riorly ; anteriorly paler, and on the front and above the eye tinged with greenish yellow. The 
forehead along the base of the bill, the lores, region around the eye, and a series of pointed 
whisker-like feathers below the eye, are black ; the latter margined above and below by greenish 
blue, like that on the top of the head, and separated from it by the color of the back. The 
occipital crest is also margined with black. On the middle of the throat are three or four much 
elongated compact feathers, which are black, with greenish blue margins near the base. The 
inside of the wing, especially the inner webs of the quills, are strongly tinged with yellowish 
rufous. 
In life the iris was yellow, the bill black, the feet dark chestnut.
