This species is not the Cinclus leucocephalus of Tschudi, as I as- 

 certained this summer by taking my specimens to Neufchatel 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 back. 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 Cinclus 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 locality, for two examples of the same bird in the British Mu-
