Adult male. Similar to that of A. v iridissima, hut witli the throat 

 rather bluer, the under tail-coverts with larger and darker diseal 

 spots, and the outer rectrices uniform steel-blue without green tips.

 pale tips to the lateral rectrices.

" About the same size as A.Jluviatilis, and with equally lengthened 

 bill ; the upper surface golden green ; the centre of the abdomen 

 and under tail-coverts pure white ; the four outer tail-feathers 

 Bteel-black, with pure white at the tip. Total length about 3-5 

 inches, wing 2'12, tail l-2o. bill 1." {Gould, I. s. e.) 



The under tail-coverts in the type specimens can hardly be 

 called pure white, as there is a dark shade over their diseal area, 

 more plainly shown in other examples. I am inclined to think 

 that Gould's type is a female, and that the male has a greenish tip 

 to the outer rectrices. If this is so, the relationship to A. viri- 

 dissima becomes very close, and the only point of distinction lies
