upper mandible emarginate. The head and nape 
are of a beautiful lively green, bounded by a black 
nuchal-collar ; the neck and breast are yellowish- 
green ; the mantle and wings are green ; the lower 
back and upper tail-coverts are deep azure blue. 
The tail, which is short and nearly even, has the two 
intermediate feathers wholly green ; the rest on each 
side have their basal half vermilion-red, bounded by 
a bar of black, the tips being green. The legs and 
toes are greyish-black. The wings are long, and, 
when closed, reach to the end of the tail. 
In this subfamily we have also placed another 
very interesting form, from Australia ; it is repre- 
sented by the Psittacus Nestor of Latham, and now 
forms the type of Wagler’s genus Nestor. This 
bird is supposed to form a connecting link between 
the Parrots and Cockatoos, though it must be con- 
fessed that more correct information respecting its 
history and habits is necessary, before its true situa- 
tion and direct affinities can be satisfactorily ascer- 
tained. The characters of the genus Nestor of Wag- 
ler are : — Bill elongate, the upper mandible com- 
pressed, hooked; the tomia sinuated, but not dis- 
tinctly toothed ; the tip projecting, with its under 
surface sulcated and deeply excavated for the recep- 
tion of the tip of the under mandible ; under man- 
dible narrow, compressed, slightly convex, or form- 
ing, when closed, an obtuse angle with the upper ;
