Idem, 1 Ô, CW: 11.7 mm (BLSZ 212). Shermans, St. Peter, subtidal, 13°16’7.25”N, 59°38’43.73”W, 1 Ô CW: 6.0 mm (MZUSP 40909).
Remarks. Specimens of Mithraculus coryphe were caught in crab traps placed on sandy bottom (~ 4m deep) on the west and south coasts of Barbados. Ovigerous females were collected in October 2019. Rathbun (1921: 84) reported several specimens of Mithraculus coryphe (three males, four ovigerous females, one juvenile, USNM 71995; two males, one female, USNM 58019; one male, two ovigerous females, USNM 71708) collected by the Barbados-Antigua Expedition in 1918 at depths of 115–198 m (64–110 fathoms) on the east coast of Barbados and at Pelican Island. Additional specimens were also collected during this expedition and are stored at the USNM (69032, 68853, 69060, 71706, 71704, 71707, 71706, 58018, 69039, 69082, and 71995). Rathbun (1921) did not mention these specimens in her report. The Smithsonian-Hartford expedition (1937) also collected specimens of Mithraculus coryphe, which were deposited to the USNM (75056, 73322). Jones (1969: 382) also reported this species for Barbados. Mithraculus coryphe can be identified by the presence of three lobes on the anterolateral margins of the carapace (Wagner 1990).
