OF NEW SOUTH WALES. 225 AUSTRALIAN FISHES. New or little known Species. By Count F. De Castelnau. Plates II. and III. The Paper that I present to the Linnean Society of New South Wales contains the description of a number of Australian Fishes, which appear to me to be either little known or entirely new to science. It forms a succession to those I have published in the proceedings of the Zoological and Acclimatisation Society of Victoria for the years 1872 and 1873, and also in the Essays con-tained in the official reports of the Victorian Intercolonial Exhi-bitions for 1873 and 1876. Beryx affinis. Beryx affinis, Gunther Catal., vol. 1, page 13. Height of body, twice and a quarter in total length without the caudal ; head, twice and three-quarters in the same, eye nearly one-third of the length of the head, preeopercule, with a rather strong flat spine at its inferior angle ; the lower limb finely serrated ; the interopercule is strongly denticulated on its lower angle, and is finely serrated at its lower margin ; operculum has three strong spines, and its margin is serrated. The dorsal fin is low at its anterior part, very high towards its centre, and from thence becomes shorter to its extremity ; it has seven spines and twelve rays ; the first ray is the highest ; this dorsal fin is long, and begins on a line perpendicular to the centre of the base of the pectoral ; caudal very strongly forked ; its inferior lobe considerably shorter than its upper one ; anal formed of four spines and twelve rays ; ventrals with one strong spine and seven rays, pectorals with thirteen rays, ] lateral line straight with six scales above and twelve below ; it extends over about forty-three scales. The general colour is of a most beautiful pink, with silver stripes on the body, the edges of the opercules of the last colour.
