Sp. 11. Tyrannus leucotis. Sp. Nov. 



White-eared Tyrant. 



T. griseo-fuscus, albens infra; vertice nigricante; cristS flava; temporibus 

 albis; striga oculari alba; remigibus acuminatis; cauda aequali. 



Gray -brown, beneath whitish ; crown blackish, crest yellow ; sides of the head 

 white with a black stripe ; quills pointed, tail even. 



Le Barbichon de Cayenne, femelle. PI. Enl. 830. f. 2 ? 



Size of the Cayenne Fly-catcher. Colour above, dark greyish-brown, 

 obscurely spotted on the back; under parts dull whitish, tinged with 

 gray on the breast, and with yellow at the vent. The crown of the 

 head, and a broad stripe on its sides, which passes from the nostrils 

 to the upper part of the ears, are blackish-brown, but this colour only con- 

 ceals a crest of beautiful yellow feathers : above the eye is a white stripe, 

 which extends to the nape ; and beneath is another, which forms a white 

 spot at the base of the ears. The wings are pointed and brown; the 

 covers and scapulars have white margins, and the four first primary quills 

 are abruptly pointed. The tail-feathers are even and brown • their mar- 

 gins, as well as those of the upper covers, being ferruginous : inner wing- 

 covers pale yellow ; tarsi short, weak, and black: the bill is of the same 

 size as that of T. Savatia. 



Inhabits Northern Brazil — rare. 



Total length 7, bill T 8 ^, wings 3f, tail 3j, tarsi ■&. 



Obs. — I strongly suspect that this bird is represented in the 

 PI. Enl., as the supposed female of Muscicapa barbata, Lath. At 

 all events this seems to be a mistake, for in specimens of the 

 female of this last species, dissected by myself in Brazil, there is 

 no appearance of the yellow crest so conspicuous in the male bird. 



Sp. 12. Tyrannus ferox. 

 Brown-crested Tyrant. 



T. griseo-fuscus, infra pallide flavus; jugulo pectoiique cinereo-albis; capite 

 cristato; remigibus semiobtusis ; cauda aequali. 



Gray-brown, beneath pale yellow; throat and breast cinereous white; head 

 crested ; quills semiobluse ; tail even.

 Le Petit Tyran de Cayenne ? PI. Enl. 571. f. 1 . 



Size of T. leucotis, but the bill is much larger. The bristles of 

 the rictus are considerably developed, and reach as far as two thirds 

 the length of the bill. , All the upper plumage is dull, grayish-brown, 

 slightly tinged with olive : the sides of the head are more cinereous ; 

 the chin and throat nearly white, changing on the breast to a very pale 

 yellow ; the crown of the head is crested, and of a uniform brownish
