 variance with all those Meliphagidw with which I am acquainted. 

 The anterior toes are long and slender, the outer connected to the 

 middle toe as far as the first joint, but the inner deeply cleft to 

 its base.

 middle anterior toe 1 | ; hind toe |.

> Independently of the magnificent plumage which adorns this 

 bird, it is one of those whose peculiar structure, at first sight, 

 seems to disturb all our artificial systems, and speculative theories. 

 In its form are united the characters of three distinct families. 

 The metallic brilliancy of its plumage, first leads us to think it a 

 Paradise bird, — a glance at its long curved bill immediately 

 reminds us of Promerops, — until, looking more closely to the 

 feet, we discover, in its strong hallux^ the complete structure of 



* The five families of this Tribe, I conceive, will be represented by the 

 following Genera : 1. Meliphaga, Lewin ; 2. Nectarinia, Illiger ; 3. Trochilus,
