Family Galatheidae Munida semoni Ortmann, 1894 Munida semoni Ortmann, 1894: 24, plate I, fig. 4. Barnard, 1950: 491, fig. 92C. Material: see page 153 of species list. Remarks: The present specimens agree closely with semoni, but differ in the following respects: the 2nd abdominal segment has 8 spines on the anterior margin, the posterior portion of segments 2 and 3 with only 1 setose transverse groove (2 in semoni), 4th joint of maxilliped 3 with only 2 strong spines (3 in semoni). In smaller specimens, there are sometimes 2 spines on the anterior margin of the 3rd abdominal segment.
