(Publislied by permission of the Trustees of the British Museum.) I. — Desceiptions of new Species. Rhinohatus Jiolcorhr/nchus, sp. n. Snout long and obtusely pointed, its praeorbital length nearly twice the distance between outer margins of eyes, and its prseoial length 3^ times widtli of mouth. Rostral carti-lage strong ; ridges widely separated, nearly parallel, slightly converging anteriorly. Diameter of eye 4 times in pra^oral length of snout ; that of eye + spiracle 1| times interorbital width. Spiracle with two folds, the outer much more prominent than the inner. Nostrils wide, f width of mouth, and nearly twice that of the internarial space. The anterior nasal valve extends inwards as far as level of inner edge of nostril, so that valves and nostrils are separated by an inter-space of equal length. Mouth straight; 64 rows of teeth in upper jaw. Dorsals equal, elevated ; the base of the first equal to its distance from extremities of pelvics, and slightly less than ^ of its distance from second dor.-<al. Caudal narrow. A distinct series of tubercles in the median line of the back, extending nearly as far as second dorsal ; a group of 3 or 4 on siioulder, 7 or 8 in front of orbit, and 3 or 4 above spiracle. Back uniform greyish brown, ligiiter at sides of rostrum and edges of pelvics ; a black blotch beneath extremity of suout. A single specimen, 28 inches in total length, from the Zululand coast, at a depth of 45 fathoms. This species appears to be related to li. leucorhi/nchus, Gunth. Ilolacanthiis acanthops, sp. n. Depth of body twice in the length, length of head 3|-. Snout not quite ^ diameter of eye, wliich is 2^ in length of head. Interorbital width 3 in iiead. rrieo{,erciiluni with the veitical margin denticulated; a strong spine at the angle, slightly more than ^ length of head, not reaching vertical from posterior margin of operculum. Subopercuhnn serrated. Suborbital with a strong backwardly directed spine, ^ length
