630 Mr. Charles Chubb on the 



The specimens from Paraguay are similar in colour 

 of plumage to those of N. pileata Bodd. from Guiana, but 

 differ in that they are larger in every respect. Total length 

 56 inches, culmen 0*65, wing 3*05, tail 20, tarsus 0*75. I 

 propose, therefore, that the Paraguay form be designated 

 Nemosia pileata paraguayensis. 



[This species is by no means common. I know nothing 

 special about its habits. — W. F.~]

Male. The chief differences which distinguish Nemosia 

 fosteri from N. guira are the wide yellow superciliary streaks 

 and frontal band, the deeper-coloured chestnut on the upper 

 breast and lower back, and the more yellow abdomen ; the 

 under tail-coverts of the type are tinged with chestnut. 

 Total length 5'2 inches, culmen 0-6, wing 2'75, tail 22, 

 tarsus 0*7. 



Female. Olive-yellow above, slightly more yellow on the 

 upper tail-coverts; under surface pale yellow, including 

 the under tail-coverts; sides of body and flanks inclining 

 to grey; under wing-coverts white. Total length 50 inches, 

 culmen 0*6, wing 2*45, tail 1*95, tarsus - 7. 



Young male in first plumage. Like the female, but brighter ; 

 the first appearance of the male dress may be recognised by 

 the tinge of chestnut on the breast and lower back, and also 

 by the mixture of black feathers on the throat. 



[This species is not uncommon in the dense forests of 

 the district, its bright yellow body and black head making 

 it very conspicuous. It is a lively and restless bird and not 

 by any means shy. The males and females are fairly well 

 balanced in number, but I have never seen them together. —
