been kindly lent to me by its describer. It represents, in 

 my opinion^ a very distinct as well as beautiful species of this 

 genus, resembling T. milleri in its upper parts, but, on account 

 of having the throat and breast green, it cannot be even placed 

 in the same group with that bird. In its rectrices it also ex- 

 hibits differences of coloration not seen in any other species, 

 the entire tail being of a light bronze-green, darkest on the 

 median pair of rectrices, graduating to a pale green at the 

 tips, and without the subterminal brown bar observed in most 

 of the species with light tails. The bill is long and slender ; 

 maxilla black, mandible flesh-colour, tip brownish black. I 

 believe the type is unique, although it is now a long time 

 since it was described, and the acquisition of other specimens 

 is much to be desired.

This species, lately described by me in this Journal, together 

 with the following one, constitute the third section of this 

 genus, with the throat and upper part of breast blue. 

 It was discovered by D^Orbigny, and the types, which are 

 unique, are in the Paris Museum. When perfect specimens 

 are obtained it wiD doubtless prove to be one of the most 

 beautiful members of the genus to which it belongs.

Hab. Peru. 



This fine species was obtained by Mr. Bartlett on the Upper 

 Ucayali, in Peru. It is remarkable for having the throat and 

 breast a violet-blue, instead of green. The few specimens 

 brought by its discoverer ai'e the only ones, so far as I am 

 aware, that have ever reached Europe ; and in collections this 

 bird is verv rare and in manv cases a desideratum.
