Show 298 Mil. C. TATE REGAN ON [Nov. 4, spines or tubercles. About 70 in a longitudinal series from the gill-opening to the caudal, about 20 in an oblique series from the base of the pectoral to the vent, and about 50 in an oblique series from the origin of the dorsal to the ventral spine. Yellowish-brown, with darker dots and points on the body and fins. Lips white, .with a semicircular white fold behind them on each side. Pacific. Total length 135 111111. Batistes capriscus has rather larger scales, and in a specimen of the same size the eye-diameter is about 3| times in the length of snout, 1| times in the interorbital width, and there are also other differences. PSEUDOMONACANTHUS PUNCTULATUS, 11. Sp. ( P l a t e X X Y . fig . 2.) Depth of body 2 j times in the total length, length of head 3 times. Snout nearly straight, but very slightly concave, about 4 times as long as the eye-diameter, which is j| of the interorbital width. Gill-opening 1| times as long as the eye-diameter, its upper and lower ends below the posterior and anterior margin of the eye respectively. D. II, 36. A. 32. Dorsal spine slightly in advance of the middle of the eye, with vertical rows of moderatesized granules or tubercles anteriorly, the two rows on each side of the median row enlarged, but not forming distinct barbs; each lateral posterior edge with a row of conical tubercles (barbs) in its lower half ; the length of the spine 1-jj- times in the length of head. Second ray of spinous dorsal not prominent. Soft dorsal and anal similar, rounded, the longest ray i the length of head. Pectoral as long as the gill-opening. Caudal rounded, half the length of head. Caudal peduncle deeper than long, with two pairs of small curved spines with points directed forward on each side. Ventral spine moderate, barbed. Scales represented by minute osseous granules. Brown, with traces of numerous small darker spots on the sides. Caudal brownish, other fins immaculate. Closely allied to Pseudornonacanthus pardalis Riipp., which has a somewhat more declivous concave snout, tubercles on dorsal spine minute, slightly shorter head, narrower gill - opening, narrower interorbital space, &c. A single specimen, 190 mm. in length, from Tahiti. PSEUDOMONACANTHUS MULTIMACULATUS, 11. Sp. (Plate XXV. fig. 1.) Depth of body 2-L times in the total length, length of head 3 times. Snout slightly concave, about 3| times as long as the eye-diameter, which is | of the interorbital width. Gill-opening 1 h times as long as the eye-diameter, its upper and lower ends below the posterior and anterior margins of the eye respectively. D. II, 36. A. 32. Dorsal spine in advance of the middle of the eve, 1 j times in the length of head, armed almost exactly as in the preceding species, but with the anterior double row of |
