406 BIRDS OF BRITISH GUIANA. 



the feathers on the upper back and some of the upper tail-coverts ; 

 median and greater upper wing-coverts dark brown margined 

 with dull white, like some of the innermost secondaries ; primary- 

 coverts uniform dark brown ; inner webs of flight-quills hair- 

 brown ; tail-feathers dark brown, fringed with oiive-grey on the 

 outer webs, and the two outer feathers on each side marked with 

 white on the apical portion of the inner webs ; a slight indication 

 of a pale streak from the base of the bill to above the eye ; sides 

 of face, throat, and breast pale yellow, becoming bri{j;hter and 

 deeper in colour on the last ; sides of body grey tinged with 

 yellow ; abdomen and under tail-coverts greyish white like the 

 under wing-coverts, axillaries similar but more grey, the marginal 

 under wing-coverts narrowly barred with brown ; under surface 

 of flight-quills hair-brown ; lower aspect of tail also hair-brown 

 blotched with white on the two outer feathers. 



Total length 123 mm., exposed culmen 10, wing 71, tail 46, 

 tarsus 20. 



Adult male. Differs from the adult female in having the top of 

 the head uniform black, the back broadly streaked with black, and 

 the under surface/white boldly marked with black on the sides of 

 the throat and sides of the body. Wing 70 mm. 



This species is not represented in the McConnell collection, and 

 the specimen described was collected by the late Henry Whitely on 

 Mount Roraima, 3500 ft., in January 1884. Whitely collected 

 another female in the same district in November 1883, and a third 

 one on the Kamarang River in January 1886. These are now in 

 the British Museum, Salvin-Godman collection. It may be 

 observed that the late Dr. Bowdler Sharpe referred to'them as 

 immature (Cat. B. Brit. Mus. x. p. 650), but I cannot regard the 

 one described above as such, as it appears to have just passed the 

 breeding-season. 



I propose, therefore, to use the name introduced by Spix for 

 this bird, as there seems to be some doubt about its migration.
