are orange, and are surrounded by a narrow circle of black feathers ; the head 

 and neck are nearly pure white ; the lower part of the neck, the breast and 

 belly, are beautiful pale rose-red, of a paler tint upwards, and appearing con- 

 siderably darker when the feathers are put aside ; a narrow collar of deep 

 black surrounds the neck obliquely, widest at the back part, and with the 

 black feathers more interrupted as it surrounds the throat ; the back and 

 wings are bluish pearl-grey ; the first quill is the longest, and has the outer 

 web black until within an inch of the base, where it passes into blackish-grey ; 

 the tail is cuneated, besides which the two centre feathers exceed the length 

 of the inner ones very considerably ; the tarsi are strong and short, and, with 

 the feet, are bright vermilion-red ; the claws are brownish-black, and sharp. 



The total length of this specimen is fourteen inches ; the extent of the 

 wings about twenty-nine inches.
