and the streaks are sparse, and so indistinct as to be in some places scarcely 

 appreciable. The wash extends for some distance along the sides under the 

 wings. 



An intermediate, and perhaps more usual state of plumage during the winter 

 differs in some respects from either of the preceding. Tbe centres of the 

 feathers of the upper parts are nearly as dark as in tbe adult, but they are 

 every where rather broadly tipped with pure white. In other respects the 

 plumage generally is much like that of the adult, except that, as might be ex- 

 pected, the wash on the jugulum is very light and much restricted, and the 

 streaks very indistinct. 



Upon inspection of Andubon's figure of the male of his Tringa Schinzii, I was 

 inclined to think that it was taken from a specimen of the present species. It 

 represents a male in the act of flying, and shows plainly the upper tail coverts, 

 which are entirely dark colored, as are also the upper parts generally. In the 

 collection, however, I find a specimen of the true Bonaparlei, labelled " St. 

 Augustine. Fla.," received from Mr. Audubon, which is in all probability the 

 original of the figure. It is in the peculiar dusky state already mentioned, and 

 agrees very nearly with the plate. His figure of the female is undoubtedly 

 that of a true Bonaparlei. The fact of his remarking that " In some individuals 

 about six of the middle tail coverts are black, the lateral barred with white 

 and dusky," show that he was acquainted with both species, but considered 

 the differences as dependant upon sex or age. The diagnosis given by Mr. 

 Cassin, in the General Report, of Tringa Bonapartei, points unmistakeably to that 

 bird ; but on the examination of the four specimens there enumerated, I find 

 three of them to be of the present species. The differences were most unac- 

 countably overlooked by that accurate ornithologist, though on a very cur- 

 sory comparison of the types of the descriptions in the present article, with 

 specimens of A. Bonapartei, he pronounced them to be totally distinct. 



The first specimen of tbe present species procured were taken by Dr. Hayden, 

 during the exploration of Nebraska, by Lieut. Warren. There are also speci- 

 mens in the collection from Fort Kearney, by Dr. Cooper, from the Zuni river, by 

 Dr. Woodhouse, and from the vicinity of Great Slave Lake, by Mr. Kennicott 

 and Mr. Ross. These widely separated localities would seem to indicate a 

 habitat co-extensive with that of A. Bonapartei, and probably embracing the 

 continent of North America, east of the Rocky Mountains. I have never seen 

 it, however, from the Atlantic coast. 



In presenting to the scientific world this my first new species, I should do 

 violence to my feelings, did I give it any other name than the one chosen. To 

 Spencer F. Baird, I dedicate it, as a slight testimonial of respect for scientific 

 acquirements of the highest order, and in grateful remembrance of the unvary- 

 ing kindness which has rendered my almost daily intercourse a source of so 

 great pleasure, and of the friendly encouragement to which I shall ever feel in- 

 debted for whatever progress I may hereafter make in ornithology.
