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. The centres of the 
feathers of the upper parts are nearly as dark as in the 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 Bonapartei , 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 Bonapartei. 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 the 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.
