The adult birds agree exactly with the female from S. Pedro, Upper Rio Negro, 

 in the British Museum (coll. Natterer), and with an adult from the Caura valley, 

 Venezuela, in the Tring collection. The forehead, pileum, and ear-coverts are 

 clear cinnamon-rufous, the remainder of the sides of the head ochraceous-buff ; 

 the foreneck and chest pale greyish brown, and the middle of the abdomen plain 

 white without dusky cross-lines.

Nos. 1100, 1181, 1217. (?<?¥, Hnmaytha, Is, 29. viii., 11. ix. 06. " Iris brown, 

 feet greenish, bill black or blackish grey." — Wing 185 — 190 ; bill 30 — 31 mm. 



The top of the head is dark cinereous, some of the feathers being narrowly 

 fringed with blackish ; the under parts (except the white throat and the variegated 

 foreneck) are rather pale brownish buff, almost white along the middle of the 

 abdomen. In Nos. 1006 and 1217 there are no white dots on the lower back and 

 rump, while they are very well pronounced in No. 1181. 



A specimen from the island of Maraj6, near Par;i, has the top of the head 

 blackish, and the under surface much brighter and more ochreous buff. 



The uumerons white spots on the wings and the clear chestnut under tail- 

 coverts render this species easily recognizable among its affines.

The first-named specimen is practically identical with others from British 

 Guiana and .Surinam, and I doubt, therefore, the possibility of separating a "pale 

 variety" from the liio Madeira. 



The young birds are more brownish than the adults, and distinctly, though 

 narrowly barred with rufesceut buff on the back, upper wing-coverts, and outer webs 

 of the secondaries.
