HE New World genus Catoptrophorus has been placed between Hetero- scelus and Totanus in the American Ornithologists' Union Check-list of North American Birds (1957). Th ere is but a single species, divided into two subspecies, semipalmatus and inornatus. The current edition of the Check-list does not provide common names below the species level, but it is convenient, and should confuse no one, to continue to use the terms "Eastern Willet" for C. s. semipalmatus and "Western Willet" for C. s. inornatus, although the terms "coastal" and "inland" would be more appropriate. Some confusion as to the status of the two forms on the western Gulf coast has existed in the past. Ridgway (1919) considered that the breeding form on the coast of Texas was inornatus, although he gave one breeding record for semipalmatus from Texas. Griscom and Crosby (1925:440, 531), aware of this confusion, collected breeding specimens from the vicinity of Brownsville, Texas, which Jonathan Dwight examined and identified as semipalmatus. However, they considered that the breeding birds from northeast Texas were probably of the western form. Subsequently, Bent (1929) concluded that all the coastal breeders were semipalmatus and that inornatus breeds only inland in the western states and the Canadian provinces. This view has been con- curred in by others, and the ranges are so indicated in the 4th edition (1931) and the 5th edition (1957) of the A.O.U. Check-list. Ridgway's (1919) mea- surements and descriptions need to be revised to accord with this latter de- termination of the distribution of the two subspecies. The ranges of these two subspecies as quoted from the current Check-list are: C. S. semipalmatus-"Breeds in southwestern Nova Scotia (locally) and from southern New Jersey and Delaware south along the Atlantic coast to Florida; from extreme southern Texas (possibly Tamaulipas) eastward along the coast of Louisiana, the islands off southern Mississippi and Alabama, to the west coast of Florida; also locally in the West Indies (the Bahamas, Grand Cayman, Beata Island, St. Croix, Antigua). Winters locally along the Gulf of Mexico coast (Tamaulipas, Texas, Louisiana, Florida), on the south Atlantic coast from Virginia to Florida, and in the West Indies (Bahamas, Greater Antilles) ; south to Central America (rarely on the Pacific side), Venezuela (Margarita Island), British Guiana, and northern Brasil (Par&). Casual north to Newfoundland and Prince Edward Island." C. s. inornatus-"Breeds locally from eastern Oregon, Idaho, central Alberta, southern Saskatchewan, and southern Manitoba south to northeastern California, western Nevada (Douglas County), central Utah, northern Colorado, western and northern Nebraska (rarely), and eastern South Dakota; formerly in western and southeastern Minnesota and Iowa. Recorded in summer south along the Pacific coast of Mexico to Panama and Ecuador. Winters locally from northern California (Humboldt Bay) south to the Galapagos
