85. Amazona auripalliata Lkss. ? 



One specimen, apparently a young bird, and doubtfully referred to 

 this species. Compared with four specimens of A. auripalliata, includ- 

 ing one without a trace of yellow on either hind-neck or forehead,* this 

 specimen differs in the shade of green, which is decidedly more of a 

 grass-green above and more of a Paris-green hue beneath, the throat 

 being pale glaucous-green and the belly tinged with emerald; the me- 

 dian portion of the forehead is yellow, slightly mixed with green, the 

 sides of forehead and the crown glaucous-green, the occiput and hind- 

 neck parrot-green with blackish terminal margins to the feathers, these 

 much broader and very distinct on sides and hinder portion of neck. 

 The bill is dusky, becoming whitish on end and edge of under mandible 

 and on tip and lateral base of upper mandible, below cere. The size is 

 also less. Whether this specimen is really the young of A. auripalliata 

 or of some undescribed species can be determined only by examination 

 of additional material.

Two specimens, June 13 and 16.

 is of a decidedly more yellowish green beneath than either of the other three exam- 

 ples, which are all from Costa Rica. The coloration is otherwise essentially the same, 

 however, except that there is no trace of yellow on hind-neck or forehead.
