Show 704 MR. F. D A Y O N N E W INDIAN FISHES. [June 27, fringed externally. A short distance external to the posterior nostril is a sharp spine, leading backwards from which to above the angle of the praeoperculum is a spiny ridge containing five more directed backwards. Along the angle and lower border of praeoperculum are three denticulations-the superior a strong spine, the others blunted ; there are also three fleshy tentacles along its border, and one on the side of the praeoperculum. Interoperculum with a blunt spine and tentacle. Operculum with a bony ridge along its centre, ending in two spines. A ridge containing three spines passes from the posterior inferior margin of the orbit to the upper margin of the opercle and commencement of the lateral line, and has two minute spines below it. Another spiny ridge extends from the posterior superior margin of the orbit backwards, and one spine between it and the ridge below it. Orbit with a strong spine at its anterior superior margin, one at its posterior superior margin, and one at its superior margin, which has attached to it a long wide tentacle on a narrow base. Several fleshy tentacles exist along the edge of the snout, a large one above the angle of the mouth, and two on the extremity of the upper jaw; there are also three rather large ones on the lower jaw. Teeth villiform, in numerous rows in both jaws, also in a V-shaped patch on the vomer, but none on the palate. Fins. Dorsal spines moderately strong, the third the longest; interspinous membrane rather deeply cleft, and extended beyond each spine. Pectoral broad at its base, its twelve lower rays un-branched, and minute fleshy appendages attached to them. Ventral spine strong. Anal-first spine short, second and third of equal length, but the second twice as strong as any in the fish. Caudal cut square at its extremity. Scales in rows proceeding backwards and upwards. Some on the upper part of the operculum ; head otherwise scaleless. Lateral line in twenty-three or twenty-four tubes. Colours. Of a general rose-colour, marbled with greyish; the spines on the head are darker than the surrounding parts. One or two irregular grey bands with dark edges exist on the tail. The dorsal and anal are also banded; and the pectoral has numerous bands on it. This species differs from the S. venosa, C. & V., which has no orbital tentacle, and of which the third anal spine is the longest and strongest, and the caudal fin is rounded, &c.
