48 Lawrence W. Powers Remarks; Records of ovigerous females include the west coast of Florida in March, April, June and September (Lyons et al., 1971) and from November through February (Rathbun, 1925). These crabs are often covered with a number of other organisms, including actinians, sponges, and rhizocephalan barnacles (Rathbun, 1925), and bryozoans, ascidians, and a red algae, Calathamnion byssoideum, as reported by Wass (1955). Regional lists include Florida (Wass, 1955; Tabb and Manning, 1961; Dragovich and Kelly, 1964; Abele, 1970; Lyons et al, 1971; Menzel, 1971), Campeche (Hildebrand, 1955), and the Gulf of Mexico (Chace, 1956). Coelho (1971c) listed it from depths of 24 to 90 m, off Brazil. Podochela sidneyi Rathbun, 1924 (Proc. U.S. Nat. Mus. 64: 1) Rathbun, 1925, p. 39, pis. 12-13; Williams, 1965, p. 242, figs. 219, 223H; Felder, I973a,p.49„pl. 7,fig. 4. Range: North Carolina; Dry Tortugas; west coast of Florida to central Texas coast; off north coast of Yucatan; northwest coast of Cuba. Depth: shallow water to 187 m (tol02fm). Habitat: mud, broken shell, sand, coral, and rock bottoms; on alga-covered surfaces. Remarks: Hildebrand (1954) collected specimens off Louisiana and Texas with small Styela (ascidians) attached to the legs, and some were covered with a dense hydroid growth. Listed from Florida by Wass (1955), Abele (1970), and Menzel (1971) and from Texas by Hildebrand (1954) and Leary (1967). Pyrojmaifl Stimpson, 1871 Pyromaia arachna Rathbun, 1924 (Proc. U.S. Nat. Mus. 64: 1) Rathbun, 1925, p. 131, pis. 42-43; Pequegnat, 1970, p. 182. Range: off Soutli Carolina; off west coast of Florida to off east coast of Mexico; throughout all quadrants of the Gulf of Mexico. Depth: 183to384m (100to210fm). Habitat: off mud, mud-sand, and mud-shell bottoms. Remarks: Rathbun (1925) reports ovigerous females off Florida in March. Listed from the Gulf collections of the R/V Oregon by Chace (1956) and from Texas by Leary (1967). Pyromaia cuspidala Stimpson, 1871 (Bull. Mus. Comp. Zool. 2: 110) Hay & Shore, 1918, p. 455, pi. 38, fig. 4; Rathbun, 1925, p. 129, text-fig. 49, pi. 4); Chace, 1940, p. 57; Williams, 1965, p. 240, figs. 216, 223E,- Pequegnat, 1970, p. 181. Range: North Carolina; south Florida; Florida Keys and Straits; Dry Tortugas; west coast of Florida; off Caribbean coast of Yucatan; north and south coasts of Cuba. Depth: 27 to 549 m (15 to 300 fm). Habitat: mud, sand, rock, coral, and pebble substrates. Remarks: Chace (1940) noted that this crab autotomizes its legs readily. Williams (1965) reports ovigerous females from off Florida in February and July.
Slenor/iync/iMs Lamarck, 1818 Crabs of the Gulf of Mexico 49 Slenorhynchus selicornis (Herbst, 1788) (Versuch Naturgesch. Krabben u. Krebse,vol. l,p. 229) Common Names: Arrow Crab; Arana del Mar Hay & Shore, 1918, p. 435, pi. 37, fig. 8; Rathbun, 192S, p. 13, te.xt-fig. 3, pis. 2-3; Rathbun, 1933, p. 6, fig. 1; Chace, 1940, p. 5S; Williams, 1965, p. 244, figs. 222, 223K; Felder, 1973a, p. 48, pi. 7, fig. 1; Pequegnat & Ray, 1974, p .237, figs. 11-12; Yang, 1976, p. 157. Range: North Carolina to south Florida; Bermuda; Bahamas; Florida Keys and Straits; Dry Tortugas; west coast of Florida to south Texas; north and east coasts of Yucatan; north and south coasts of Cuba; Jamaica; Puerto Rico; St. Thomas, Virgin Islands to Dominica; Netherlands Antilles; Colombia; Maranhao to Santa Catarina, Brazil. Depth: near surface to 1489 m (814 fm). Habitat: rock, coral, sand, sand-shell, and pebble bottoms; from sponges; off wharf pilings and rock jetties. Remarks: The eastern Atlantic records cited by Rathbun (1925) are referred to S. lanceolatus (Brulle) by Yang (1967) and Barr (1975). Yang (1976) provides evidence that 5. selicornis contains two species, one in shallow water, the other a deep water form. Williams (1965) states that this crab is more commonly collected at depths of 100 fm or less. Various authors use a variation of the genus name (e.g., Stenorynchus, in Williams, 1965). Yang (1967) describes larval stages. Ovigerous females occur off Texas in May and June (Hildebrand, 1954) and throughout the spring and summer over most of its range. Regional lists include Florida (Wass, 1955; Menzel, 1971), Mississippi (Franks et ah, 1972), Texas (Hildebrand, 1954; Leary, 1967), and the mid-ocean Gulf (Chace, 1956). Hartnoll (1965a) provided some notes on the biology and growth of Jamaican populations and Barr (1971, 1975) studied its biology in the Virgin Islands. Its occurrence in Brazil was noted by Coelho (1971c) and Coelho and Ramos (1972). Agonistic behavior of this crab is discussed by Schone (1968) and antennule chemosensitivity was tested by Hazlett (1971). Herrnkind, Stanton and Conklin (1976) described commensal relationships with an anemone in Florida. Subfamily MAJINAE Samouelle, 1819 Temnonolus A. Milne Edwards, 1875 Temnonotus granulosus A. Milne Edwards, 1875 (Crust. Reg. Mex., p. 83) As T. simplex—"Rathhun, 1925, p. 342, pi, 249, figs. 10-12, As T. granulosus—Rathhun, 1925, p. 341, pi. 249, figs. 7-9; Chace, 1940, p. 65, fig. 22. Range: north coast of Cuba; Barbados. Depth: 183 to 478 m (100 to 260 fm). Habitat: coral, broken shell bottoms.
