258 FLYCATCHER. 



three quarters. Bill broad and flat, straight, and a trifle bent at the 

 tip, furnished with hairs at the base, and black ; eyes large ; head 

 bluish white, mixed, as far as the eye, with buff; front buff-colour; 

 rump, and outer webs of the outer tail feathers white, the rest of the 

 plumage full black ; tail feathers in general little more than one inch 

 and a half long, but the two middle ones exceed them more than 

 three inches; these last are webbed, as usual, at the base and ends, 

 but the middle part consisting of little more than a bare shaft; legs 

 black. 



Inhabits Paraguay in the winter only, and is rare. Male and 

 female always together; found in deep woods, generally perched on 

 some tall decayed tree, from which it springs on insects. One of 

 these in Mr. Bullock's Museum ; a second in that of Lord Stanley. 



In the collection of Mr. Comyns, of Mount Pleasant, is a third, 

 which probably differs in sex. In this the crown of the head is dirty 

 white, without the least tinge of buff-colour, and the white on the 

 rump takes up much less space; otherwise it entirely corresponds 

 with the other. The total length of the bird is nine inches, and the 

 tail feathers including the long ones, ten in number ; the last 

 exceeding the latter by four inches, and there is no white on the 

 the outer web of the exterior feather. This probably is the female.
