Chelipeds with the extremities of fingers rounded and spoon-shaped. Ambulatory legs with a dactylo-propodal articulation formed by a rounded prolongation of the propodal lateral margin sliding against and beneath a projecting button situated proximally on the lateral margin of the dactylus: this structure sometimes hardly indicated or differentiated but then the extremity of the dactylus being always bifid.
