 back, and rump, oil green, having the centre of 

 each feather umber brown, except on the latter

 white, or on the scapulars yellowish oil green ; 

 in the latter the outer feathers being white except 

 at the base, the second tipped with white ; the 

 throat and breast are buff orange, inclining on the 

 sides of the latter to oil green, and on the sides 

 of the neck and on the breast, having each fea- 

 ther marked at the tip with a triangular spot of
