Remarks. This is the first record of Callinectes marginatus from Barbados; caught by hand in nearshore rubble at low tide and in crab traps placed on sandy bottoms (~ 4m deep) on the west and south coasts of Barbados. This species is very abundant in nearshore rubble habitats on the south coast. Jones (1968b: 187) described a new species, Callinectes humphreyi Jones 1968 , which he listed as endemic to Barbados. His description of this presumed new species, however, is based on the colour (white) of juvenile specimens. Williams (1974: 739) synonymized Callinectes humphreyi with Callinectes ornatus Ordway, 1863 . According to Williams (1974: 741), Jones had indicated that the type specimen of Callinectes humphreyi was lost by accident in 1969 and therefore could not be examined. Given Jones’ (1968b) minimal description of Callinectes humphreyi and stated similarity to C. ornatus, Williams (1974) assumed that C. humphreyi was a juvenile colour variety of Callinectes ornatus . This study collected one juvenile specimen of Callinectes marginatus ( Fig. 16E View FIGURE 16 ), which has the same colour (white) as the presumed new species ( Callinectes humphreyi ) described by Jones (1968b: 187). Given this, we suggest that the synonym Callinectes humphreyi is in fact based on a juvenile of Callinectes marginatus instead of Callinectes ornatus . Callinectes marginatus can be identified by four teeth on the frontal margin of carapace, median pair greatly reduced, lateral pair triangular shaped, and short first gonopods in males, which reaches about mid-length of thoracic sternite VII ( Williams 1974).
