108 BIRDS OF BRITISH GUIANA. 



whitish at the base and dusky at the tips of the feathers ; 

 superciliary line j-ellowish white ; chin and throat also yellowish 

 white, becoming darker on the breast and middle of the abdomen 

 and more olive on the sides of the body and under tail-coverts ; 

 under wing-coverts orange-bufF ; under surface of flight-quills 

 pale brown with yellowish-white inner edges. 



Total length 162 mm., exposed culnien 16, wing 90, tail 65, 

 tarsus 20. 



Adult female. Similar to the adult male and differs only in 

 having the under tail-coverts pale rufous. Wing 79 mm. 



There is a specimen in the British Museum, sexed as female, 

 from Ourumee, which differs from those described and others in 

 the collection in having the superciliary streak and the feathers 

 adjoining the hinder ear-coverts rufous. I am inclined to think, 

 however, that this must be a sign of immaturity, as some of the 

 tail-feathers are not fully grown. 



This subspecies is not represented in the McConnell collection ; 

 the birds described are in the British Museum, and were collected 

 by the late Henry Whitel}'^ at Kamacusa and Ourumee^ 



•There is also in the collection a male individual from Barro 

 do Rio Negro, said by the late Dr. Sclater to be one of the 

 typical specimens of P. e. erijthrocercus. The Guiana bird differs, 

 however, from this and another from Para, collected by the late 

 A. R. Wallace, in being darker on the upper parts, with more 

 brown and less olive ; this applies also to the under surface, 

 especially on the sides of the body. I have, therefore, separated 

 these subs]-)ecifically.
