Show 1873.] SCLATER AND SALVIN ON AMERICAN LIMICOLCE. 453 This species is of the same type as C. unicarinatum, Lamarck, but is quite distinct, being more depressed, and having a much larger umbilicus and more expanded keel. 3. Notes on the Range of several American Limicola. By P. L. SCLATER, M.A., Ph.D., F.R.S., and OSBERT SALVIN, M.A. [Eeceived March 22, 1873.] 1. HIMANTOPUS. A n examination of the specimens of American Stilts in the collection of Salvin and G o d m a n has convinced us that two species have hitherto been confounded under the name Himantopus nigricollis. The northern bird, which must retain Vieillot's name, extends from the United States southwards as far as Brazil. Its southern representative, found in South Brazil, the Argentine Republic, and Chili, is easily known by having the whole top of the head white, and a broad white band across the upper back just below the neck. It must bear the name brasiliensis of Brehm, who has shortly described this species in his ** Vogel Deutschlands,' the previously given term melanurus of Vieillot, based on Azara, if really intended for this bird, involving an error in fact. The synonymy of the two species will stand as follows:- Fig. Head of Himantopus nigricollis. 1. HIMANTOPUS NIGRICOLLIS. Himantopus nigricollis, Vieill. N. D. x. p. 41, Enc. Meth. |
