![swollen and coarsely reticulate laterally; uropods just shorter than the 6th segment; rami equal, inwardly curved, and narrow, the outer being a little broader than the inner. Distal end of the crest on the last four thoracic legs increasing gradually in height from before backwards; ungues of all the legs curved, moderately long, and increasing in size backwards but only very gradually, so that those of the last pair are only a little longer than those of the first pair. Length 35 mm.; breadth 17 mm. XVII. Genus Meinertia St ebbing. 32. Meinertia carinata Schiodte & Meinert. Ceratothoa carinata Sch. & Mein. Naturhist. Tidsskr. iii. 13, p. 327 (1883). Loc.

Although the anal segment and uropods are much damaged, there is no doubt in my mind that this specimen belongs to the above species, presenting as it does three very characteristic features : namely, the swollen basal joints of the first antennae, the pectination of the 3rd and 6th-7th legs, and the constriction of the ungues of the other legs. In two points, however, it differs; for the median concavity in the anterior margin of the first segment is slightly deeper (not shallower) than the lateral, and the first four abdominal segments are all subequal, the fifth being only very slightly longer. XIX. Genus Rocinela Leach. 34. Rocinela mundana, sp. nov. (Plate XXXV. figs. 9-9 a.) Tale Sab. “ From the gills of a freshwater skate.” Flagellum of 1st antennae 4-articulate, of 2nd antennae 12-articulate; ©yes distant, reniform, with the anterior end trun- cate ; ocelli fairly large, numerous. Front bluntly triangular, projecting in front of the eyes, and only just concealing the base of the 1st antenna; 1st thoracic segment longer than the rest, which are subequal, its anterior border trisinuate; epimera small, increasing in size backwards, the last just overlapping, with its blunt point, the posterior angle of the last segment; 1st abdominal segment partly concealed, distinctly shorter than the rest; its posterior border sinuate, those of the rest becoming straighter towards the telson.
