Pleopods of the male. Exopods of the second, third and fourth pairs stouter than the corresponding endopods and armed with shorter setae. In the third pair only, the exopod is considerably longer than the endopod— in the other pairs the two rami are of equal length. Uropods. Exopod longer and broader than the endopod and slightly bowed outward; unarmed portion of the outer margin very short, less that one- sixteenth of the total length, and terminated by two unequal spines; endopod slightly longer than the telson; armed with a single long slender spine distal to the statocyst.
