POLYERATA.

This genus was generally merged with JDamopMla until Herr Heine separated it. 

 The form of the tail distinguishes it, the rectrices being all of nearly equal length, the 

 outer pair being equal to the middle pair and only very slightly shorter than the rest. 

 The glittering colour of the under surface is confined to the breast. 



Two species constitute the genus, one of which spreads from Costa Rica (missing a 

 considerable portion of the State of Panama) to Colombia and Western Ecuador. The 

 other is restricted to the neighbourhood of Chiriqui.

Gould's description of this species was based upon a trade skin from Bogota 1. The 

 bird is now known as not unfrequently represented in the collections of the bird-hunters 

 of Bogota, and as occurring southwards in Western Ecuador and northwards to the 

 Quindiu mountains and the State of Antioquia^ to the line of the Panama Railway. 

 Here we seem to lose it in the rest of the State of Panama, but it reappears in Costa 

 Rica, where several collectors have found it. Its place in Western Panama seems to 

 be occupied by P. decora, a closely allied form.
