Crepidula planaSay, 1822a, p. 226-227, [Say 1832b, pl. 44; Collin 2000: neotype, fig. 6 left] [Basis of the current name] Type Locality: New Jersey, Maryland, Carolina, Georgia, East Florida [Woods Hole, Massachusetts, 41°30'N, 70°40'W (by neotype designation of Collin 2000: 1509)] Range: 48°N to 6°N; 97.75°W to 57°W Depth: 0 to 91 m (live 1 to 73 m) Maximum Reported Size: 40 mm Distribution: Canada: Nova Scotia, New Brunswick; USA: Massachusetts, New York, New Jersey, Maryland, Virginia, North Carolina, South Carolina, Georgia, Florida: East Florida, West Florida; USA: Louisiana, Flower Garden Banks, Texas; Mexico: Tamaulipas, Veracruz, Tabasco, Campeche State, Cayo Arcas, Campeche, Yucatan State, Campeche Bank, Alacran Reef, Quintana Roo; Costa Rica, Panama, Colombia, Venezuela: Gulf of Venezuela, Sucre, Isla Margarita; Bermuda, Jamaica, Puerto Rico; Virgin Islands: St. Croix; St. Vincent & the Grenadines: Grenada; Surinam References: Bousfield (1964) N; García-Cubas (1971) W; Porter (1974) {D}; Hoagland (1983a) S; Odé (1983a) DL; Lyons (1989b) l; Díaz & Puyana (1994) M; Macsotay & Campos (2001); Simone (2006a) Comments: Collin (2000) redefined Crepidula plana, restricting its range to Georgia and north. Records of C. plana in Florida and the Gulf of Mexico may apply to C. depressa and C. atrasolea. Records from Brazil may be C. intratesta. The identity of records from the Caribbean and northern South America has not yet been determined, so they are maintained here under C. plana pending resolution. Combining Genera: Crypta
