Of this species Mr. Whitely sends us three specimens, a 

 male and two females, noting that the iris of one of the 

 females was dark hazel, the legs and toes greenish brown, 

 and the claws yellowish horn-colour. Two of these spe- 

 cimens were shot on June 22nd and one on July 5th, 1881, 

 all in the Merume Mountains. 



The species is evidently closely allied to C. leucogonys, the 

 patria of which is supposed to be Brazil, and of which a 

 figure will be found in 'Exotic Ornithology,^ p. 37, pi. 19. 

 It differs in the points indicated above, the clearly defined 

 rufous patch on the throat being a conspicuous feature. 



ViREOLANIUS .LEUCOTIS. 



In ' The Ibis ' for 1878 (p. 443, pi. ii.) Salvin published a 

 note on this species, identifying it with V. icterophrys of 

 Bonaparte and other more recent writers. He, however, 

 separated it from V. chlorogaster, Bp., which he considered 

 peculiar to Guiana, V. leucotis being from the upper portion 

 of the Amazons valley. 



Mr. Whitely^s collections contain two beautiful specimens 

 of the Guianan bird, which, if the above determination were 

 correct, should be called V. chlorogaster ; but on comparing 

 them with the true V. leucotis, from Ecuador, we now 

 see no valid grounds for separating these birds, and pro- 

 pose to unite V. chlorogaster as well as V. icterophrys 

 under Swainson^s old title V. leucotis. It is true that some 

 variation can be traced in the amount of white on the 

 cheeks ; but this is not of specific value, as the extent 

 varies in specimens from the same locality. 



By uniting all these supposed species under one name all
