Iliacantha liodactylus Rathbun, 1898 (Bull. Lab. Nat. Hist. State Univ. Iowa<br />

4: 291)<br />

Rathbun, 1937, p. 186, text-fig. 41, pi. 55, figs. 1-2; Felder, 1973a, p. 39, pi. 5, fig. 2.<br />

Range: west coast of Florida; ? Haiti; Puerto Rico; St. John, Virgin Islands;<br />

Trinidad; Alagoas to Bahia, Brazil.<br />

Depth: 9 to 130 m (5 to 71 fm).<br />

Habitat: mud substrates.<br />

Remarks: Recorded by Chace (1956) from the R/V Oregon cruise in the Gulf<br />

of Mexico. The locality records cited for this species and for Callidactylus asper<br />

by Rathbun (1937) are not in agreement with the latitudes and longitudes listed.<br />

Both species are listed from the east coast of Haiti, as recorded by the Johnson-<br />

Smithsonian Expedition of 1933, but the coordinates as listed would place C.<br />

asper east of Puerto Rico and place /. liodactylus on the east coast of the Dominican.<br />

Republic. Leary (1967) lists /. liodactylus from Texas and Felder (1973a)<br />

repeats Leary's listing, but I know of no published collection records to verify<br />

the presence of this species in the northwestern Gulf. Listed from Brazil by<br />

Coelho (1971b) and Coelho and Ramos (1972).
