neous, throat and breast with narrow black striations ; under wing- 

 coverts pale yellow ; bill black, reddish at the base : feet dark 

 flesh-colour : whole length 5 inches, wing 2*2, tail 2*8. 



Hob. Colombia. 



The long tail and lengthened tarsi at once distinguish this 

 species, which might well be generically separated, but is certainly 

 closely allied to Anceretes.

Subfamily III. ELAINEINCE. 



In the Elaineince or Olive-Tyrants the bill, instead of being ex- 

 panded laterally and much bristled, as in the Platyrhynchince, is 

 compressed, and in most cases very sparingly provided with rictal 

 setae. The feet are feeble, the wings generally short, and the struc- 

 ture is generally adapted for arboreal life. 



The general colour of these birds is of olive-green and sombre 

 brown, in conformity with that of the dense forests to which they 

 mostly resort. But the bright-tinted and reed-frequenting Oyanotis 

 is aberrant both in colour and habits. 



The Elaineince are distributed over the whole of the Neotropical 

 Begion, one species only (Ornithion imberbe) having been as yet 

 ascertained to occur within the limits of the Nearctic Begion.

In Cyanotis the constriction of the bill and the smoothness of 

 the rictus are carried to an extreme which is unparalleled anion o- 

 other Tyrannidce ; and although there is little doubt that the affini- 

 ties of Cyanotis are with this family, it is certainly a most anomalous 

 form, both in structure and colour, and must, I think, eventually 

 be allowed the rank of a distinct subfamily. For the present, I
