SWINDERN'S LOVE-BIRD. 139 



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- 

 vig, when closed, an obtuse angle with the upper ;
