Show 1884.] GENERA SICYDIUM AND LENTIPES. 165 a small median papilla above the maxillary suture, upper lip with slight median cleft ; maxillae contain an angle of about 60°; horizontal teeth conspicuous. The total length of the body (without the caudal) is four and two third times the length of the head ; the width and height of the head are equal and two thirds of the length. The height of the body is about a quarter of the length. Scales rather large, those on the neck, belly, and tail being smaller than the rest. The diameter of the eye is contained five and a half times in the length of the head and about three in the interorbital space. The length of the pectoral equals the length of the head ; the length of the caudal is about one sixth of the total length of the body. The third dorsal spine is produced into a short filament not so high as the body ; second dorsal not so high as the body. Colour greenish above, with eight blackish cross bars ; a blackish band along the side, most distinct on the base of the caudal and along its middle rays ; dorsal and anal fins immaculate, the latter with a blackish intermarginal band ; caudal with a black horseshoe-like mark ; pectoral and ventral yellow. Total length 3 ^ inches. Hab. Amboina. One adult specimen. 16. SICYDIUM NIGRESCENS, Gthr. Sicydium nigrescens, Giinth. 'Challenger' Shore Fishes, p. 60, pi. xxvi. fig. C. D. 6~. A. ^. L. lat. 80. L. trans. 16. Teeth in the upper jaw tricuspid. G u m beneath the upper lip smooth, no median papilla above the maxillary suture ; no median cleft in the upper lip ; maxillae are at right angles to one another ; horizontal teeth conspicuous. The length of the body (without the caudal) is four and a half times the length of the head ; the width of the head is rather greater than the height. The height of the body is one fifth of the length. Scales on the occiput, anterior part of body and belly in irregular series and much smaller than those on the rest of the body. The pectoral is considerably, and the caudal much longer than the head. The diameter of the eye is one seventh of the length of the head and rather more than one third of the interorbital space. The first, second, and third dorsal spines are produced into filaments, the third, which is the longest, is nearly twice the height of the body ; second dorsal higher than the body; the posterior rays are much produced, extending beyond the root of the caudal. Colour uniform brownish-black; vertical fins black; pectoral and ventral brown. Total length nearly 5 inches. Honolulu. One adult specimen (type). |
