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).
