Tliis species is not the Cinchts leucocephalus of Tschudi, as I as- 

 certained this summer by taking my specimens to Ncufchatel and 

 there comparing them with the type. Tschudi's bird is much larger 

 and has the white below confined to the breast, and no white hack. It 

 is in short quite a different bird. The most peculiar thing however 

 about my two specimens is, that one is larger than the other, and 

 has the bill strikingly longer. After some hesitation I have attri- 

 buted this to sex, though I am not aware of a similar difference 

 occurring in the bills of other Cincli. I may remark, however, that 

 though this bird is seemingly much like Cinchts in form, I cannot 

 help thinking that, when we know more about it, we may find occa- 

 sion to refer it to a different genus. My examples were picked out 

 of a large number of ordinary Bogota skins, of which they have the 

 usual unmistakeable appearance. The bird described by Lafresnaye 

 was brought from Pasto by Delattre, and a specimen in the Paris 

 Museum — marked Cinclus leucocephalus — is said to be from the 

 vicinity of Quito. Sir William Jardine possesses examples from the 

 same locality.

Mr. Eyton's collection contains the type-specimen of this very 

 well-marked species of Tyrant, which I believe to have been hitherto 

 overlooked. It is labelled " Guyaquil," and that is no doubt its 

 right localitv, for two examples of the same bird in the British Mu-
