immature male from near Paramaribo (Triug Museum), however, lias the bright- 

 coloured belly, and a specimen from British Guiana (Mas. Brit.) the uniform 

 upper tail-coverts of the Upper Amazonian form, which therefore Joes not 

 appear to be separable.

This specimen agrees perfectly with our series from Goiaz and from the interior 

 of S. Panlo, the throat and the middle of the belly being white, the back warm 

 brown with a strong rnfescent tinge on the nropygium. Young birds in corre- 

 sponding plumage of E.f. cabanisi (Le'ot.) (= arenaceus Scl. & Salv.) are of a much 

 duller earthy brown on the upper parts.

Differs from our large series * by its paler foreneck, this being scarcely shaded 

 with greenish. In the coloration of the upper parts it, is perfectly identical with 

 examples from Trinidad. 



Thanks to the kindness of my friend Dr. Lorenz, of Vienna, 1 was enabled to 

 examine the specimen from Borba mentioned by Von Pelzeln (I.e. note '), aud 

 found it to belong to the present species.
