Material examined: Barbados, Carlisle Bay , St. Michael, subtidal, 13°05’07.15”N, 59°36’36.90”W, 1 Ô CW: 29.6 mm ( BLSZ 020 ). Idem, 2 Ô, 1 ♀ CW: 10.5, 10.0, 10.3 mm ( MZUSP 40886 , 40887 ) .

Remarks. This is the first record of Macrocoeloma nodipes for Barbados. Caught in crab traps on rocky bottom (~ 4m deep) on the south coast of Barbados. Rathbun (1921, 1925) reported two species from the genus Macrocoeloma that were not collected during the present study, these are Macrocoeloma eutheca ( Stimpson, 1871) and Macrocoeloma intermedium Rathbun, 1901 . Specimens of Macrocoeloma eutheca (one female, USNM 72901; one female, USNM 58010) were collected at depths of 0–126 m (0–70 fathoms). Additionally, one female specimen (USNM 72261) of Macrocoeloma intermedium was collected from Pelican Island at a depth of 36 m (20 fathoms).
