Side-plate 1 slightly produced forwards, but antero-inferior angle rounded; 2 larger than the others in <}, longer than deep; 3 and 4 deeper than long, about as deep as their segments; 5 with anterior lobe much deeper than posterior lobe. Pleon dorsally smooth; postero-inferior angle of segment 3 rounded. Telson rounded-triangular, about as broad as long, with two spinules on dorsal surface, each flanked on outside by a Fig. 146. Megamphopus blaisus, a. Gnathopod 1 j\ b. Gnathopod z<$, with palm and finger further enlarged, c. 2nd joint of peraeopod 3. d. Telson. Antenna 1, 3rd joint subequal to ist, flagellum 12-14-jointed, accessory flagellum as long as ist flagellar joint, 1-2-jointed, with a minute terminal joint. Antenna 2 about as long as antenna 1, flagellum 12-jointed. Epistome without spinous projection. Third joint of mandibular palp shorter than 2nd, but not so shortened as in cornutns (Sars, pi. cc). Gnathopod 1, 5th joint elongate, lower margin undulate, with oblique marginal rows of long setae, 6th shorter than 5th, ovate, palm shorter than hind margin but undefined except by a slender spine, finger overlapping palm. Gnathopod 2 in the g strongly developed, folded transversely across the body, 2nd joint stout, 5th nearly as long as 2nd, with fascicles of long setae on lower margin, 6th shorter than 5th, oblong, lower margin with fascicles of long setae, palm very short, oblique, concave, defined by a strong spine
