There are also specimens in this Museum from Charles Island in the same

have a higher and absolutely perpendicular front, the frontal lobes project- 
ing even further forward than in specimens from Acapulco labelled “ Grapsus

face of the carpus and hand of the chelipeds is uniform red. The ambulatory
