336 GREEN-TAILED SPARROW. 



some animal or reptile, I never could discover, but the prize was lost 

 to me for ever. I searched the forests for months afterwards, but ne- 

 ver saw another." 



GREEN-TAILED SPARROW. Fringilla chlorura. 



The following notice respecting this bird is by Dr Townsend : — 

 " July 12. 1834. I shot this morning a new and singularly marked 

 Sparrow. The specimen is, however, unfortunately young, and the 

 plvmiage is not fully developed. I feel in great hopes of finding the 

 adult in similar situations on our route. It is a true Fringilla. The 

 head is of a light brownish colour, spotted with dusky ; back varied 

 with dusky and greenish-olive ; rump brownish, spotted with dusky ; 

 wings plain dusky, the outer vanes, as well as the tail-feathers, green- 

 ish-yellow ; axillaries yellow ; throat white ; a longitudinal line of 

 black on either side ; breast and flanks white, spotted or streaked with 

 black ; belly whitish ; vent tinged with light brown, inclining to ochre- 

 ous." " The measurements of this species I find I have not given. 

 I probably omitted them from the supposition that I should at a future 

 time find the perfect bird. In this I was, however, disappointed : I 

 never saw it afterwards." 



TOWNSEND'S MOCKING THRUSH. Turdus Townsendi. 



" On the 12th of August 1834," says Dr Townsend, " I saw a 

 Thrush, cinereous brown above, whitish below, with a long rounded 

 tail, every feather except the two middle ones largely tipped with 

 white. About two months subsequently, on the Shoshone River, West 

 of the Rocky Mountains, I killed one of these birds ; but it was moult- 

 ing, and I foolishly threw it away in the expectation of finding it on 

 the Columbia. I never saw it afterwards." 



WHITE-TAILED AND WHITE-RUMPED CORMORANTS. 



Phalacrocorax leucurus. Phalacrocorax levconotus. 



" At Cape Disappointment,'" says Dr Townsend in his notes trans- 

 mitted to me, " there are two Cormorants, at least in spring, about the 

 size of Phalacrocorax resplendens, one with a white tail, the other with 

 a white rump."
