ventre medio et crissoalbo, lateribus Jlavicantibus : rostro fusco, 

 pedibus nigris. 



Long, tota 48, alse 2-3, cauJse 2-0. 



Hab. In Brasilia. 



I have several specimens of this well-marked Brazilian species in 

 my collection, but have never been able to find any other name than 

 the late M. de Lafresnaye's MS. term, which I have ascertained to 

 be correct from examination and comparison of the type in his 

 collection. 



This bird is closely allied to Phyllomyias brevirostris (Spix) (Cab. 

 et Hein. Mus. Hein. ii. p. 57), but readily distinguishable by its 

 dark cinereous head and white belly, &c. 



11. Phyllomyias semifusca (PI. XXXVI. fig. 1), 



Supra /usco-murina, superciliis obsolete albidis : tectricum ala- 

 rium et secundariarum marginibus pallidioribus, fulvescenti- 

 albidis: subtus lactescenti-albida, ventre stramineo vix tincto : 

 rostro superiore nigricante, inferiore pallide fusco ; pedibus 

 nigris. 

 Long, tota 4*3, alse 2-3, caudse TP. 



Hab. In Nova Granada, ad Sanctam Martham {Verreaux). 

 I have one example of this bird in my collection, procured by 

 M. Verreaux's collector at Santa Martha, on the north coast of New 

 Granada. Its structure is quite that of the preceding species and 

 P. brevirostris, except that the bill is rather more elongated. 



12. Tyrannus inca. 



Tyrannus inca, Licht. in Mus. Berol. 



Fuscescenti-cinereus, alis et cauda fuscis, marginibus dilutioribus : 

 pileo cristato nigro, crista intus Icete flava : subtus cinereus, 

 ventre et crisso fuscescente adumbratis : rostro et pedibus 

 nigris. 

 Long, tota 7"5, alse 4'0, caudse 3'3, tarsi 0'6. 

 Hab. In Bolivia. 



This is a very distinctly marked species of the true Tyrannus, of 

 which I possess one example. I have used the name given to it by 

 Lichtenstein in the Berlin Museum. The external primaries are 

 acuminated towards the points, the three first being also deeply 

 emarginated 0*4 inch from their extremities.
