Remarks: The first reports of this species in North America were from Florida<br />

(Provenzano, 1961), from Mississippi, the only Gulf records (Perry, 1973), and<br />

a second Florida finding (Gore and Grizzle, 1974). Norse (1972) noted habitat<br />

preferences in Jamaica. Listed from Brazil by Coelho (1971a) and Coelho and<br />

Ramos (1972).<br />

Callinectes danae Smith, 1869 (Trans. Connecticut Acad. Sci. 2: 7)<br />

Range: Bermuda; southeast Florida; Dry Tortugas; north coast of Cuba;<br />

Caribbean coast of Yucatan; Jamaica; Hispaniola; Puerto Rico; St. Croix to<br />

Barbados; Trinidad; Netherlands Antilles; Belize to Panama; Colombia to Santa<br />

Catarina, Brazil.<br />

Depth: shore to 75 m (to 41 fm).<br />

Habitat: from nearly fresh to full sea water, possibty in hypersaline lagoons;<br />

Occurs among mangroves and in mudd}'- estuaries in Brazil; Off beaches and in<br />

open water.<br />

Remarks: Williams (1974a) believes that earlier records of this species from<br />

Chile are erroneous. Records of this species along the U.S. Gulf coast should be<br />

referred to C. similis, as per the revision by Williams (1966, 1974a). Records<br />

from east Florida indicated this crab's presence on the ocean side of islands in<br />

Biscayne Bay and its absence from the Florida Keys (Park, 1969). Norse (1972)<br />

noted habitat preferences in Jamaica. Listed from Brazil b}^ Coelho and Ramos<br />

(1972). Morrison and Morrison (1952) studied hemolymph coagulation in<br />

Bermuda specimens.<br />

Depth: shore to 7.5 m (to 4 fm).<br />

Habitat: estuarine and marine waters, possibl}^ fresh water; around river<br />

mouths and in mangrove areas.<br />

Remarks: Williams (1974a) comments on a lack of specimens from the<br />

Guianas and northern Brazil and that a locality record from Chile is erroneous.<br />

Leary (1967) listed this species from Texas on the basis of a single specimen<br />

from near Port Aransas, tentatively identified by Gordon Gunter, but not available<br />

for confirmation by Williams. Leary (1967) stated that the frontal teeth<br />

pattern was very similar to C. danae (= C. similis), thus the Gulf record for this
