Similar to A. I. leucocephala, but slightly larger; red of throat, 

 cheeks, etc., deeper, somewhat more extended posteriorly, that of 

 abdomen also deeper and much more extended, sometimes occupying 

 greater part of under surface.

AMAZONA LEUCOCEPHALA CAYMANENSIS (Cory). 



CAYMAN PARROT. 



Similar to A. I. leucocephala but the green of a decidedly more 

 yellowish hue, and green of crown and occiput less strongly (some- 

 times not at all) tinged with blue; 6 slightly larger. 



<* Ten specimens. 



6 The specimens examined are all in worn and more or less soiled plumage, so that 

 it is difficult to determine with exactness the points of difference from A. I. leucocephala. 

 The white of the head is very much duller than in Cuban specimens, but this may 

 result from an actual staining of the feathers.
