 T. melanoptera (Hartlaub MS.) Sclater, Proc. Zool. Soc. Lond. xxiv. 1856. p. 235 (January 1857. — 

 Eastern Peru, etc.). 



Nos. 295, 477. S S ad., Calama, 29. vii., 28. viii. 1907. " Iris brown, feet and 

 bill black."— Wing 94, 98 ; tail 70, 72 ; bill 13^, 14 mm. 



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, etc., in the Munich Museum. The other (No. 295) slightly 

 points towards T. jj. 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. 

 Zool. xii. pp. 273-4.
