Description of $?, mm., from "Ingolf" St. 25. Head has a rather long, somewhat acute rostrum ; lateral corners acutely produced. Body somewhat compressed, but without dorsal carina or teeth, except for a single, blunt, erect tooth on 3rd metasome segment. Metasome segment 1 has lower hind corner rounded,. Fig. 63. Cvessina monocuspis q (P. 4 $ is from "Thor St. 99, urosome in lateral view from a J from "Thor" St. 100, and nrosome in dorsal view from a (J from "Ingolf" St. 25.) segment 2 nearly rectangular, segment 3 acute-angled. Sometimes there seems to be traces of small, round, colourless eyes. Antenna 1 has 1st joint heavy, abt. i1/2 times as long as head, apically acutely produced en underside; 2nd joint not so heavy and somewhat shorter, apically with a triangular elongation on median side: 3rd joint very short; flagellum consists of much over 25 joints (apex is lost in all the specimens!, and the whole antenna is probably I1/"—2 times as long as the whole body. Antenna 2 lias peduncle much more slender than in antenna 1; 5th joint somewhat shorter than 4th joint; peduncle reaches to apex of antenna 1 and is as long as flagellum; flagellum has abt. 16 joints. Pereiopod 1 has sideplate very little, quadrangular; all joints slender; 4th joint apically not pro- duced; 5th joint somewhat curvate, abt. 2 times as long as 6th joint; 6th joint lias the sides almost parallel; dactylus feeble, somewhat curvate, half as long as the preceding joint. Pereiopod 2 lias sideplate rather huge. 27*
