With a very close general resemblance to A heloisce, this species may 

 be immediatelv distinguished by the very different form of the outer 

 primary, the redder and more uniform color of the throat-gorget, and 

 the shorter bill. The peculiar characters of the two may be contrasted 

 as follows : —
