'â Station 3124. most as long as anten- nular ; scale tapering, meastued on outer margin exceeding the carapace; its spine long, but still not so advanced as the blade. Outer maxillipeds not quite reaching tip of ros- trum ; first pair of feet to middle of antennal scale; second pair ex- tending just beyond maxilliped. The posterior margin of the third abdominal segment is produced backward in a strong lobe; the abdomen is strongly bent at this point; the fourth segment is spineless; the sixth is less than twice as long as the fifth, and a little shorter than the telson, which is armed with four pairs of lateral spines.
