(syn. Prosobonia Ϯ Tuamotu Sandpiper P. parvirostris) Gr. αιχμη aikhmē point, lance; ῥυγχος rhunkhos bill; "Examining the types of Tringa parvirostris, PEALE, which has been referred to T. rufescens [= Calidris subruficollis], with a query, by Dr. Schlegel, and made a variety of the same by Bonaparte, I find that not only is it an entirely different bird, specifically, but that it is scarcely congeneric. Having the extremely small bill of T. rufescens, this organ is smaller still, slenderer, and without the peculiar forward outline of the feathers at its base, which characterizes T. rufescens. In the mounted specimens, the wings fall far short of the end of the tail instead of reaching rather beyond. There is none of the peculiar mottling of the primaries, which is such a strong feature of T. rufescens; the tail is barred transversely, and there are other differences in coloration. Should it be deemed worthy of subgeneric separtion [sic], it may be called Æchmorhynchus parvirostris." (Coues 1874); "Æchmorhynchus Coues, Bds. Northwest, 1874, p. 506. Type, by monotypy, Tringa parvirostris Peale." (Peters 1934, II, 258).
