TIio prospiit ,s])pci('.s i.s clo.soly allit'd to AniiutteUa maritime, Bifl'xN., and can 

 with (litticulty lu' distiiij^'uislii'd in its wintor i<lumag<'. A ehisc comparison, however, 

 shows that in this livery A. CokchI has decidedly less of the purjde gloss to the (h)rsal 

 region, where the plumbeous borders to the featiiers are both broader and jjaler; tiu' 

 t'oreneek is also invariably scpiamated or streaked with white^ and not uniforndy 

 mouse-gray, as in vinrittiixi. It is still more nearly related to A. j'tilonwinis, Coii;s, 

 of the I'rybilof Islan<ls, but averages much smaller, and is always very much darker- 

 colored in every stage of plumage. The three are not only strictly congeneric, but 

 are very probal)ly the descendants of one original stock ; but, since no intermediate 

 specimens have been observed in a large series of each kind, they may l)e considered 

 as having passed the " varietal stage," so that we may treat them as distinct species. 

 Both Mr. Hurting and Dr. Goues were wrong in referring A. pfilonicDiin to the sauu' 

 group as l'f/!(lii(i (i/fiina, which bears oidy a superficial resemblance in coloration, the 

 details of form being quite different. 



While I have been unable to Hud any name which can be applied to this species, 

 it ap))ears that Pallas refers to it in his description of 2'rbiga ar<iuiiteU<i, in " Zoiig, 

 Rosso-Asiat." II. p. 19l>, since \w says that specimens of his species from the Kurile 

 Islands are marked with ru.sty yellow, as in the bird under consideration : "Corpus 

 supra plumis fuscis, margine pallidis {in CurUira ore fvi'nigineo-hdois) . . . pectorc 

 cinerescens (m vurUlcn v(tr. Itifi'sreus)." All Alaskan references to Tringa maritima 

 of course apply to the present species.

Sp. Char. Similar to A. maritima, but larger, and much ligliter colored. Adult, brccding- 

 plwnmge : Back and scainilai-s light clay-color, or ochracoous, the centre of each feather black, the 

 tips of many of them narrowly whitish ; rump and upper tail-coverts dark slate, the feathers in-
