108 Lawrence W. Powers Platypodia spectahilis (Herbst, 1794). Platypodia Bell, 1835 This species was transferred to a new genus, Platypodiella, by Guinot (1967b). leaving this genus without a representative in the Gulf of Mexico. Platypodiella Guinot, 1967 Platypodiella spectahilis (Herbst. 1794) (Natur. Krabben u. Krebse, vol. 2, p. 153) As Platypodia spectabUis—Rathhun, 1930, p. 247, text-fig. 39, pi. 102, fig. 4; Ralhbun, 1933, p. 54, fig. 47. As Platypodiella spectabilis—Guinot, 1967b, p. 562; Felder, 1973a, p. 65, pi. 9, fig. 10. Range: Bermuda; Bahamas; Florida Keys; Texas; Veracruz, Mexico, Jamaica; Puerto Rico; Virgin Islands; Guadeloupe; Martinique; Barbados; Curagao; Fernando de Noronha, Brazil. Depth: 4 to 13 m (2 to 7.5 fm). Habitat: coral reefs; under stones. Remarks: This species is illustrated by Forest & Guinot (1966, fig. 7). Listed from Brazil and described by Fausto Filho (1974). Guinot (1967b) transferred this species from Platypodia to the newly-erected genus. Pseudomedaeus Guinot, 1967 Pseudoniedaeus agassizii (A. Milne Edwards, 1880) (Crust. Reg. Mex., p. 270) As Leptodius agassizii—Hay & Shore, 1918, p. 441, pi. 34, fig. 6; Rathbun, 1930, p. 307, pi. 141, figs. 4-5; Williams, 1965, p. 192, figs. 174,183H. As Pseudomedaeus agassizii—Guinot, 1968a, p. 726, fig. 25; Felder, 1973a, p. 67, pi. 9, fig. 11. Range: North Carolina; Florida Straits and Keys; Dry Tortugas; west and northwest coasts of Florida; Louisiana and Texas; Virgin Islands. Depth: 7 to 82 m (4 to 45 fm). Habitat: sand, shell, rock, and coral bottoms; from sponges. Remarks: Costlow and Bookhout (1968a) described larval development. Williams (1965) noted morphological variability over the range of this species and reported ovigerous females from April to November. Listed from Florida by Wass (1955) andAbele (1970). Abele (1970) commented on variation in anteriolateral teeth and tuberculation of the chelae. Rhithropanopeus Rathbun, 1898 Rhithropanopeus harrisii (Gould, 1841) (Rept. Invert. Massachusetts, p. 326) Hay & Shore, 1918, p. 441, pi. 35, fig. 5; Rathbun, 1930, p. 456, text-fig. 75, pi. 183, figs. 7-8; Williams, 1965, p. 187, figs. 169, 183C; Christiansen, 1969, p. 81, fig. 33, map 27; Felder, 1973a, p. 67, pi. 9, fig. 14. Range: New Brunswick to south Florida; west and northwest coasts of Florida;
Crabs of the Gulf of Mexico 109 Mississippi to Veracruz, Mexico; introduced to west coast of United States and to various parts of Europe in recent times. Depth: intertidal to 37 m (to 20 fm), most common to 9 m (5 fm). Habitat: freshwater and estuarine areas; upper bays with salinities usually less than 20 ppt; on 03rster reefs; on living and dead vegetation; under rocks and in old cans and other debris. Remarks: Ryan (1956) provided an account of the life history of this crab, based on studies in Chesapeake Bay. Williams (1965) reviewed much of the pertinent literature on this species. Studies of larval forms include those of Connolly (1925), Hood (1962), Chamberlain (1962), Costlow (1966), Costlow, Bookhout and Monroe (1966), Bookhout et al (1972), Ott and Forward (1976), andSandifer (1973). The European populations were considered a separate subspecies, R. h. trldentaius Maitland, by Buitendijk and Holthuis (1949), but this was questioned by Wolff (1954). Christiansen (1969) reviewed the distributional data for this species in Europe and treated the different populations as conspecific, with no distinct subspecies recognized. Reports of this crab on the U.S. Pacific coast include Jones (1940), Felice (1958), and Ricketts and Calvin (1968). Regional lists include Florida (Wass, 1955; Tabb and Manning, 1961; Abele, 1970; Menzel, 1971), Mississippi (Christmas andLangley, 1973), Louisiana (Behre, 1950), Texas (Hedgpeth, 1953; Leary, 1967), and the northwestern Gulf (Fotheringham and Brunenmeister, 1975). Physiological studies include data on osmoregulation (Jones, 1941; Verway, 1957; Kalber and Costlow, 1966; R. I. Smith, 1967), effects of pesticides on larval development (Bookhout and Costlow, 1976), metabolism and larval development (Rosenberg and Costlow, 1976), effects of juvenile hormone on larvae (Christiansen, Costlow and Monroe, 1977a, b), sterol synthesis in larvae (Whitney, 1969), androgen glands (Payen, Costlow and Charniaux-Cotton, 1971), and eyestalk hormones (Skorkowski, 1972). Tetraxanlhus Rathbun, 1898 Tetraxanthus bidenlalus (A. Milne Edwards, 1880) (Crust. Reg. Mex., p. 353) As T. rugosus Rathbun—Rathbun, 1930, p. 459, pi. 185. As T. bidenlatus—Chace, 1939, p. 52; Chace, 1940, p. 36. Range: Florida Keys; north and south coasts of Cuba; Grenada. Depth: 168to293m (92to 160fm). Habitat: sand and coral bottoms. Remarks: The species described and illustrated by Rathbun (1930) as T. bldentatus was actually a new species, which Chace (1939) named T. rathbunae (= T. rathbuni). The species Rathbun (1930) listed as T. rugosus n. sp. is T. bldentatus. Tetraxanlhus rathbunae Chace, 1939 (Mem. Soc. Cubana Hist. Nat. 13: 52) As T. bldentatus (A. Milne Edwards)—Rathbun, 1930, p. 458, pi. 184. As T. rathbunae—Chace, 1939, p. 52; Chace, 1940, p. 37. As T. rathbuni—Pequenat, 1970, p. 195.
