One of these specimens is typical of melanoptera, having mere traces of dark 
olive-grey edges to some of the outer primaries, exactly like examples from the 
Caura Valley, Trinidad, ete., in the Munich Museum. The other (No. 295) slightly 
points towards 7. p. palmarum of Eastern Brazil, though the greenish edges of the 
remiges are duller and less distinct than in the latter. Birds from the vicinity of 
Pard, however, agree in coloration with the typical race, but are smaller. Cf. Nov.
