In pseudocarinata, however, the telson and 6th pleon segment are completely fused, there is no transverse ridge, and the level of the telson is flush with that of the 6th pleon segment.

Halio'phasma hermani n. sp. (Fig. 1.) Integument not strongly indurated, not pitted. Dorso-lateral keels feeble, dorso-lateral grooves distinct. Medio-dorsal pits deep. Eyes well developed. Pleon segments 1-5 with indistinct Fig. 1.—Haliophasma hermani n. sp. a, hind margin of 6th pleon segment, with telson, and sagittal and cross-sections of latter, b, peraeopod 1. c, outer ramus of uropod. Telson arising beneath the arcuate hind margin of 6th pleon segment; obovate, apex semicircularly rounded, upturned, ventral surface evenly but rather strongly convex, dorsal surface concave, with sharp medio-dorsal keel. Flagellum of antenna 1 a single joint, with minute setiferous apical rudiment of a 2nd joint; flagellum of antenna 24-jointed. Maxilliped 5-jointed. Peraeopod 1, 4th joint very broad, 5th with lower apex slightly projecting, 6th not as wide proximally as the 4th, tapering distally, palm straight. Pleopod 1 not indurated, outer surface smooth. Uropod, inner ramus slightly longer than wide, apex rounded, not reaching to level of telsonic apex, outer ramus folding over telson,.
