Adult male. Upper surface nearly uniform golden green : under 

 surface glittering golden green without any blue tint ; tail steel- 

 blue : bill black, the basal half of the mandible flesh-colour. Total 

 length about 3"2 inches, wing 1-8; tail, lateral rectrices 1-1, central 

 0-65; bill 0-7. 



Adult female. Upper surface shining golden green, duller on the 

 crown ; under surface dirty white ; ear-coverts blacliish ; central 

 rectrices lilce the back, lateral greyish white, with a wide steel-blue 

 subterminal band ; bill black, the mandible pale towards the base. 



I have, through the kindness of the authorities of the Derby Mu- 

 seum at Liverpool, had an opportunity of examining the type of this 

 species, and find that it has the base of the mandible flesh-coloured. 

 It follows that Mr. Elliot was wrong in his application of the name. 

 Comparing the type of C. angustipennis with that of C. chrysogaster, 

 which is in the Gould Collection, I find them absolutely alike, as 

 Gould, in his monograph, stated they were. T. gibsoni, Eraser, the 

 tj-pe of which is before me, is a female of 0. angustipennis.
