Description ?. Body glabrous. Head acute in front, sharply keeled dorsally. Side- plate 4 as mplumosa (Sars, 1895, pi. Hi), 5th with posterior lobe a little deeper than in that species. Postero-inferior angle of pleon segment 3 produced in a strong, slightly upturned process as in plumosa or obtusifrons (Stebbing, 1888, pi. lvi), no oblique row of setae on surface. Segment 4 with gently convex dorsal profile beyond the basal depression. Telson, lobes parallel-sided, apically broadly rounded. Antenna 1, flagellum 10-11-jointed, ac- cessory flagellum 7-8-jointed. Antenna 2, basal joint with a large curved ensiform pro- cess, apically subacute, as in obtusifrons, 4th joint triangularly expanded, outer surface with an oblique row of spine setae, the upper ones simple, the lower plumose, upper apex with several long simple setae, lower margin with long plumose setae, and a submarginal row of simple spine setae, flagellum 12-jointed. Peraeopod 4 like that of obtusifrons, but 2nd joint twice as long as broad, upper hind angle rather prominent, hind margin concave. Peraeopod 5, 2nd joint like that of obtusifrons, 3rd distally lobed anteriorly, 4th distally lobed posteriorly. Remarks. A species allied to plumosa, but more especially it may
