Long. al. caud. rostr. tars. tib. med. dig. med. 6" 9'" 2" 2'" 9'" 18'" 9'" ll£"' As far as I can judge from a few specimens, the Golden Plover America, most nearly allied to the C. fulvus, Gmel., of Eastern Asia, is a distinct species, characterized by the longer wings. But whether this character is constant I hesitate to declare with certainty, not having compared specimens enough. 105. CHARADRIUS SEMIPALMATUS, Bp. Charadrius brevirostris, Neuw. Beitr. iv. p. 769; Burm. iii. p. 359. Charadrius semipalmatus, Leot. p. 392; Schleg. Curs. p. 30. Three specimens; two in winter dress, the third in full summer plumage. There is no difference in specimens from Brazil and from the United States. 106. TOTANUS SEMIPALMATUS (Gmel.); Leot. p. 457; Schleg. Scolopaces, p. 76. Catoptrophorus semipalmatus, Bp. One specimen in winter plumage, agreeing with North-American specimens. 107- ACTITIS MACULARIUS (L.); Schleg. Scolop. p. 83. Tringoides macularia, Leot. p. 461; Taylor, I. c. p. 95. One specimen in the dress supposed to be that of the young, having the under parts uniform white, unspotted, quite the same as in our A. hypoleucus, with which it may be easily confounded at first sight. But there exists a very good character in the markings of the outer tail-feather-in A. macularius only the outer web being distinctly barred with white and black, the inner web obscure greyish brown, instead of being both barred regularly with black, as in A. hypoleucus. 108. TRINGA SEMIPALMATA, Wils. Ereunetes petrificatus, 111. Tringa pusilla (L.) ; Schleg. Scolop. p. 55. Heteropoda semipalmata et H. longirostris, Loot. pp. 477, 480. Eureunetes mauri et E. minor, Gundl. J. f. Orn. 1856, pp.419,420. One specimen in winter dress, which agrees in every respect with specimens from Texas, Cuba, and Sitka. The variability in the length of the bill has been noticed already by Professor Baird (B. N. Am. p. 725). Our Cuban specimen (T. mauri, Bp.) has tbe bill 8'" long, like the Trinidad one (8'" E. minor, Gundl.); in the Texan specimen the bill measures 9'" ; and in the one from Sitka 1 l£'", as noticed for T. mauri by Dr. Gundlach.
