Material examined. Barbados, Batts Rock , St. Michael, subtidal, 13°08’04.81”N, 59°38’12.30”W, 3 Ô CW : 8.7, 9.8, 7.4 mm ( BLSZ 045 ). Reeds Bay, St. James , subtidal, 13°13’09.10”N, 59°38’32.44”W, 1 Ô CW: 10.0 mm ( MZUSP 40897 ) .

Remarks. Specimens of Chorinus heros were caught in crab traps that were placed on rocky bottoms (~ 4 m deep) on the west coast of Barbados. Chorinus heros was first reported for Barbados by Schomburgk (1848: 655). This was followed by the report by A. Milne-Edwards (1873: 86) of Chorinus heros for Barbados. Rathbun (1921: 81) reported one immature female specimen collected at Pelican Island by the Barbados-Antigua Expedition in 1918 (USNM 72988). Additionally, Rathbun (1925: 306–307) reported one male specimen of Chorinus heros as collected from Barbados by N.T. Gill; this specimen is stored at the Museum of Comparative Zoology (MCZ 1268).
