This species was discovered by Mr. Edward Bartlett on the Lower Ucayali River in Eastern Peru. It 

 belongs to the same section of the genus Agyrtna as A. neglecta, having, like that species, the throat and 

 npper part of the breast blue, but it differs from it in having a blue-black tail. 



The following is the original description : — 



" Crown of the head, nape, and back deep grass-green, changing to bronzy green on the upper tail-coverts ; 

 throat and chest rich blue; flanks green; centre of the abdomen greyish white; under tail-coverts bronzy 

 brown, margined with grey; tail bluish black, the upper surface of the tw^o central rectrices washed with 

 green, and the four outer feathers on each side obscurely tipped with grey in those specimens which, 

 according to Mr. Bartlett, are females ; wings deep purplisli brown ; upper mandible brownish black; under 

 mandible flesh-colour; feet dark brown. 



'* Total length 31 inches, bill 1, wing 2i, tail H, tarsi i" 



We are indebted to Messrs. Salvin and Godman for the loan of a male specimen, from which the three 

 figures in the Pbite have been drawn.
