Macrocoeloma septemspinosum (Stimpson, 1871) (Bull. Mus. Comp. Zool. 2: 113) Rathbun, 1925, p. 477, pi. 173, figs. 2^3. Range: South Carolina; Bahamas; Florida Keys; northeast quadrant of Gulf; Ceara to Rio Grande do Norte, Brazil. Depth: shallow water to 145 m (to 79 fm), rarely to 212 m (116 fm). Habitat: sand, broken shell, and coral substrates; on calcareous algae. Remarks: Listed by Chace (1956) from the Gulf of Mexico. Brazilian records include Coelho (1971a, 1971c) and Coelho and Ramos (1972). Macrocoeloma suhparallelum. (Stimpson, 1860) (Ann. Lye. Nat. Hist. New York 7: 182) Rathbun, 1925, p. 480, pi. 172; Rathbun, 1933, p. 36. Range: north coast of Cuba; Jamaica; Haiti; Puerto Rico; St. Thomas, Virgin Islands; Guadeloupe; Barbados; Old Providence Island (Carib.); Rio Grande do Norte to Pernambuco, Brazil. Depth: shallow water to 22 m (to 12 fm). Habitat; on coral reefs; in tide pools; on bottoms of sand, grasses and weeds. Remarks: Brazilian records include notes on its occurrence in the littoral zone (Coelho, 1971c) and listings by Coelho and Ramos (1972) and Fausto Filho (1974). Macrocoeloma Irispinosum trispinosum. (Latreille, 1825) (Encyc. meth.. Hist. Nat, vol 10, p. 142) Common Names: Grass Crab; Sponge Crab; Decorator Crab Hay & Shore, 1918, p. 457, pi. 38, fig. 11; Rathbun, 1925, p. 466, te.vt-fig. 132, pi. 166, fig. 1, pi. 167; Rathbun, 1933, p. 35, fig. 31; Williams, 1965, p. 263, fig. 243; Felder, 1973a, p. 53, pi. 7, fig. 9. Range: North Carolina; Bermuda; south Florida to northwest Florida; off Louisiana and Texas; Gulf and Caribbean coasts of Yucatan, Mexico; Cuba; Jamaica; Puerto Rico; St. Thomas to St. Lucia; Curasao, Netherlands Antilles; Piaui to Bahia, Brazil. Depth: shallow water to 82 m (to 45 fm). Habitat: sand, rock and shell bottoms; among submerged mangrove roots; from wharf pilings; from floating masses of Sargassum. Remarks: Rathbun (1925) listed three varieties of this species, two of which are listed here as subspecies (the typical form and M. t. nodipes), and a third, considered an intermediate form. Behre (1950) listed an unspecified form of Macrocoeloma from Louisiana and Menzel (1971) and Lyons et al. (1971) record this crab as uncommon in Florida. Ovigerous female records were summarized by Williams (1965). Hartnoll (1965a) described the biology and growth of this crab in Jamaica. Many specimens are encrusted with sponges, which are
Crabs of the Gulf of Mexico 53 attached to the hairs of the carapace and legs, providing the basis for two of its common names. Records from Brazil include Coelho (1971a, 1971c), Coelho and Ramos (1972) and Fausto Filho (1974). Macrocoeloina trispinosum nodipes (Desbonne, 1867) (Crust, de la Guadeloupe, p. 15) Rathbun, 1925, p. 468, pi. 166, fig. 2, pi. 168, fig. 2; Rathbun, 1933, p. 36; Williams, 1965, p. 264. Range: North Carolina; Bermuda; south to northwest coasts of Florida; Florida Keys and Dry Tortugas; Cuba; Puerto Rico; Antigua; Brazil. Depth: shore to 48 m (to26fm). Habitat: sand, shell, rock, and coral bottoms; grassy areas. Remarks: Rathbun (1925) lists several specimens that were covered with sponges and one crab that was encrusted with worm tubes. She reported ovigerous females from Florida in December and from Cuba in June. Listed from Florida by Wass (1955), Abele (1970), and Menzel (1971), and from the Gulf collections of the R/V Oregon by Chace (1956). Abele (1970) treats this form as a separate species and notes the need for revision of this genus. Macrocoeloina trispinosum variety Rathbun, 1925 (Bull. U.S. Nat. Mus. 129: 468) Rathbun, 1925, p. 468, pi. 168, fig, 1; Rathbun, 1933, p. 36. Range: North Carolina; Bahamas; southeast and west coasts of Florida; Florida Keys and Dry Tortugas; Cuba; Jamaica; Puerto Rico; St. Thomas, Virgin Islands; Curagao, Netherlands Antilles. Depth: low tide mark to 51 m (to 28 fm). Habitat: sand, shell, rock, and coral bottoms. Remarks: Williams (1965) followed the practice of Rathbun (1925) in treating this variety as an unnamed but distinct form, an intermediate linking the typical subspecies and M. t. nodipes. If the latter is raised to the status of a full species (as in Abele, 1970), then this variety will require reevaluation as a subspecies or species. Microphrys H. Milne Edwards, 1851 Microphrys anlillensis Rathbun, 1920 (Proc. Washington Acad. Sci. 33: 24) As M. platysoma—Hay & Shore, 1918, p. 459, pi. 38, fig. 9.

Range: North Carolina; Bimini; west coast of Florida; north coast of Cuba; Jamaica; Puerto Rico; Brazil. Depth: 4 to 38 m (2 to 21 fm). Habitat: mud, coral, sand, shell, and weed bottoms. Remarks: Ovigerous females were reported from North Carohna in September (Rathbun, 1925) and from Florida in June and from Bimini in November (Williams, 1965). Listed from Brazil by Coelho (1971c) and Coelho and Ramos (1972).
