This species is almost exactly similar to Vireo oli'cacem in colour, 

 but is considerably smaller, and differs in having the wings shorter, 

 with the first quill considerably shorter than the fifth, whereas in that 

 species it is always much longer, generally exceeding even the fourth. 

 It is intermediate between the Vireo gihus and V. olivacetis. 



SHORT-LEGGED PEWEE FLYCATCHER. 



MUSCICAPA RiCHARDSONIJ, SwAINSON. 

 PLATE CCCCXXXIV. Male. 



I HAVE much pleasure in presenting you with a rare and remark- 

 able species of Flycatcher, honoured by Mr Swainson with the name 

 of my excellent friend Dr Richardson. I found this species plentiful 

 on the coast of Labradoi", where, for a while, I thought it so nearly al- 

 lied to our Common Pewee Flycatcher, as almost to render me indiffe- 

 rent to its notes, movements, and nidification, all of which, however, 

 I at length discovered to differ considerably, especially the latter. On 

 this particular subject, on which I have already said so much, I may 

 here repeat, that birds of the same species may in some localities form 

 nests extremely different from those constructed by them in others. 

 Indeed, accustomed as I have been to this for a considerable number 

 of years, I thought it in no way remarkable to find the nest of what I 

 then considered as our Common Pewee placed in a bush, instead of 

 being placed against a rock or under a shed, for I thought the difference 

 less than that presented by the nidification of owr Common Crow Black- 

 bird, which in Louisiana deposits its eggs in the hollow of a tree, while 

 in Pennsylvania, and other districts, it constructs as regular a nest as 

 our Turdus migratorius. It was not long, however, before I discovered 

 material differences in the deportment, habits, and voice of this Fly- 

 catcher and the Pewee ; the larger size of the latter of which rendered 

 me confident that I could not be mistaken, as I frequently saw both 

 birds in the course of my daily rambles.
