" Gould, loc. cit." 



This species differs from A cerviniventris, in the much 

 greater depth of the chestnut colouring of the abdomen, 

 undertail-coverts and tail, in size it is considerably less than 

 in that species, being even smaller than A. beryl Una, to which 

 it offers an alliance in the colouring of the wings ; but from 

 which it differs in the colouring of its abdomen ; the white 

 feathers of the thighs are much developed and very conspicuous.
