Lophopanopeus Rathhun, 1898<br />

Lophopanopeus distinclus Rathbun, 1898.<br />

Transferred to the genus Micropanope by Menzies (1948), see Micropanope<br />

distincta (Rathbun, 1898).<br />

Lophopanopeus lobipes (A. Milne Edwards, 1880).<br />

Transferred to the genus Hexapanopeus by Menzies (1948), see Hexapanopeus<br />

MeZyfoia Stimpson, 1871<br />

Melyhia ihalamlla Stimpson, 1871 (Bull. Mus. Comp. Zool. 2: 144)<br />

Rathbun, \930, p. 562, pi. 230.<br />

Range: Dry Tortugas; north coast of Cuba; Jamaica; Haiti; Culebra and<br />

Vieques Islands; Barbados; Curagao; Colon, Panama; Abrolhos Islands, Brazil.<br />

Depth: low tide mark to 368 m (to 201 fm), most common to 82 m (45 fm).<br />

Habitat: coral, sand, rock, and broken shell bottoms.<br />

Remarks: The deepest recorded specimens (192 and 201 fm) are from off<br />

Havana, Cuba.<br />

Menippe mercenaria (Say, 1818) (J. Acad. Nat. Sci. Philadelphia 1: 448)<br />

Common Name: Stone Crab<br />

2^3.<br />

Range: North Carolina to south Florida; Bahamas; Florida Keys; southwest<br />

Florida to south Texas; off Yucatan Gulf coast; north coast of Cuba; Jamaica.<br />

Depth: surface and intertidal to 51 m (to 28 fm).<br />

Habitat: in estuaries and bays of near-marine salinity; from sand, shell, clay,<br />

and mud substrates; in deeper waters on offshore reefs; in turtle grass (Thalassia)<br />

beds off northwest Florida; post-larval crabs are common in deeper channels and<br />

bays, under shell fragments; older juveniles and adults are among rocks, under<br />

stones, and on and among oyster bars.<br />

Remarks: Except for the blue crab (Callinectes sapidus), this species is the<br />

most important crab commercially harvested on the Gulf coast, primarily in<br />

Florida. Williams (1965) summarizes much of the literature and accounts of<br />

the natural history of stone crabs in Texas are provided by Powell and Gunter<br />

(1968) and by Futch (1966) for Florida populations. Fotheringham and Brunenmeister<br />

(1975) offer general comments on the stone crab in the northwestern<br />

Gulf.<br />

Developmental studies include data on fertilization (Binford, 1913), zoeal<br />

stage descriptions (Porter, 1960), studies of effects of temperature and salinity<br />

on larvae (Ong and Costlow, 1970), effects of Mirex on larvae (Bookhout et al.,<br />

1972), and studies of larval energy budgets (Mootz and Epifanio, 1974). Studies
