Two strong canine teeth in front in each jaw, the lower fitting in between the upper, the other teeth in both jaws well developed conical — no posterior canine tooth visible. Colour greenish opaline, almost translucent when alive, tinged with orange along the anal fin, and with an oblong, indistinct, orange patch behind the eye, commencing on the forehead above and anterior to that organ ; tail with alternate pale blue and dull orange bars, five in number ; indistinct pale lines of the same tints on the membranes of the dorsal and anal fins, faint indications of blue spots on the scales on the abdominal and caudal regions. Eye bright orange. This specimen is a young individual, with the coloration indistinct and but imperfectly developed ; the adult will probably be of a bright orange tint, with blue spots on each of the body-scales and blue and orange bars on the tail and fins. Caught at Manly Beach, Port Jackson. I believe that it is the first species of this genus recorded from Port Jackson. Note on the occurrence on the Coast of New South Wales of the Genus Mesenteripora, Bl., (Polyzoa CyclostomataJ . By William A. Haswell, M.A., B.Sc. Among an interesting series of Polyzoa obtained with the dredge off Broughton Islands to the north of Port Stephens during the recent dredging excursion organised by the Australian Museum, were a number of specimens of the remarkable cyclostomatous genus Mesenteripora. Most of them were attached to the laminee of a species of Biflustra, or the thick cylindrical branches of a species of Cellepora, which was obtained in large quantity.
