B. 7. Body oval, compressed, and elevated, the height compared with the length being as 1 to 2\ or 2f . It is of a blackish-grey colour, beautifully reflecting white and iridescent hues. A coppery lustre is reflected in certain lights from the sides of the body and the head. The hinder portion (black) of the body is covered with large striated scales ; those on the head have finely pectinated edges, those on the body have simple borders. Between and in front of the eyes the head is scaleless. The head is short and abrupt ; its length to that of the whole fish is as 1 to 2f . The eye is vertically oval ; the pupil a pale grey, the iris a dark brown. It is contained about 4^-times in the head, and is removed from the muzzle by a space equal to about 1^ times its longer axis. Above it there is a space equal to \^ times its longer axis, and below it a space equal to twice that axis. There is only one opening on each side to the pituitary sac, and that is small and transversely oval. The mouth-cleft is small and subvertical ; the under jaw rather longer than the upper. The superior border of the mouth is formed by the narrow premaxillary, much of which, when the mouth is closed, passes underneath the maxillary. The latter is much dilated below, and its exposed portion is triangular. It reaches back to the vertical from the middle of the eye. There are small scales on the premaxillary, and large ones on the maxillaiy. There is a broad band of small, conical, slightly curved teeth, nar-rowing backwards in each jaw, the innermost row being slightly longer. There is also a narrow band of small teeth on the palatines ; but the vomer and tongue are unarmed. The tongue is broad, fleshy, and black. Inside the teeth in each jaw there is a black flap ex-tending from one side of the mouth to the other. The opercular pieces are clothed with scales, and their margins are unarmed and rounded. The long dorsal fin is very high and falcate in front, this portion being covered with small scales. The fin is low behind, and near its termination the broadly expanded apices of the rays project beyond the membrane. The length of the fin, compared with the total length of the fish, is as 1 to 2\. The pectoral fins are long, pointed, and subfalcate, and they reach back as far as the middle of the dorsal fin. The base is clothed with small scales ; and in the axil there is a membrane bearing eight or nine scales, which connects the upper Ann. i^ Mag. N. Hist. Ser. 3. Vol.xxi. 21
