Lower lateral spine of carapace farther back;anterior median spine much larger and farther forward; it projects wellin front of the posterior line of the rostrum is narrower, and ascending atan angle of about forty-five degrees. Theanterior margin of the hand is more longi-tudinal than in C. munita. The divisions ofthe ventral carina of the thorax in the maleare much more spiniform in this species.

Distribution. — Off the Trinity Islands, Alaska, 159 fathoms (Albatrossstation 2853); Santa Catalina Island, California, 80 fathoms (Albatrossstation 3664); southwest of San Nicholas Island, California, 158 fathoms(Albatross station 2898). One specimen taken at each locality. In the foregoing species the first four segments of the abdomen aresmooth. We now come to a group also resembling C. munita in generalappearance, but having the abdomen in front of the fifth segment more or less carinated. CRANGON VARIABILIS Rathbun. Crangon -variabilis RATHBUN, Proc. U. S. Nat. Mus., xxiv, 890, carapace is much like that of C. munita, but is nearly half as long as the abdomen. The rostrum is short, convex from behind forward and the tip rounded andthickened. The anten-nal scale has a concaveouter margin
