Cirrepedesmus Bonaparte, Compt. Rend. Acad. Sci. Paris, xliii, p. 417 (1856).
Type by taut., Charadrius atrifrons Wagler.
In this genus there is no white ring round the neck and the bill is decidedly shorter than in Charadrius and is shorter than in Pagoa, the dertrum is much swollen and occupies about half the culmen; the legs are comparatively short, the feet medium and the tarsus reticulated throughout. I cannot separate the Large Sand-Plover generically from Cirrepedesmus, all the characters seeming to be the same except that Pagoa, which Mathews creates for the Large Sand-Plover, has a slightly longer bill.
