Adult male. Very similar to that of P. guyi, but the upper tail- 

 coverts and the proximal half of the rectrices tinged with blue 

 instead of green. The females and young males of the two forms 

 appear undistinguishable with certainty.

Distinguishable from P. e/iii/i and P. emUicp. by having the bases 

 of the rectrices blue-black and the under tail-coverts white. These 

 differences are more conspicuous when adult males are compared, 

 but they can be traced in specimens of both sexes and all ages.
