DESCRIPTIONS OF NEW OR RARE AUSTRALIAN FISHES. By E. Pierson Ramsay, F.R.S.E., and J. Douglas-Ogilby. Pteroplatea australis. sp. nov. Disk rather less than twice as wide as long ; tail three-eighths of the length of the disk, without spine or rudimentary fin, but with faint indications of a cutaneous fold above and below. Spiracle provided with a tentacle. Teeth with a long median and two short lateral cusps. Skin smooth. Dark-brown, almost black above ; white beneath ; tail with two interrupted white rings about midway. This fine species, belonging to a genus hitherto unknown from Australia, was forwarded some years ago by Mr. J. Brown from Cape Hawke, N. S. "Wales, and measures twenty-three inches across the disk. It is possible that this may be identical with the Mediterranean P. altavela, but in the absence of books of reference it is impossible to settle the question satisfactoi'ily owing to the insufficient descrip-tion given in the British Museum Catalogue.
