NEW OR INSUFFICIENTLY DESCRIBED FISHES. 55 
Mouth but little oblique, the tips of the premaxillaries somewhat 
below the level of the eye, the posterior border of which is midway 
between the tip of the opercle and that of the snout; maxillary 
extending to rather beyond the anterior border of the pupil, the 
width of its distal extremity half the eye-diameter ; interorbit narrow 
and concave, with a pair of feeble parallel ridges, which expand 
behind into a cup-shaped figure enclosing the occiput; width of 
interorbit 1*75 in the eye-diameter ; supraorbital ridge everywhere 
smooth. Posterior spine of preorbital curved and directed backward ; 
preopercle with four spines, the upper long and acute, the others 
short and blunt ; a short but strong and sharp humeral spine. 
Cheeks covered by a bony plate, bearing a well-defined median ridge 
from which run oblique striae ; a few small scales behind the tip 
of the maxillary. 
Length of soft portion of dorsal 235 in that of the spinous ; 
first dorsal spine one fifth shorter than the last, which equals the 
two preceding ones and the third, and is 1*2 in the tenth, which 
slightly exceeds the pair adjacent to it ; second, third, and fourth 
rays longest, but not extending so far back as those which imme- 
diately succeed them and just reach the base of the caudal. Caudal 
fin rounded. Anal originating below the twelfth dorsal spine, the 
middle rays longest, not quite so long as, but reaching further back, 
than those of the dorsal ; first spine 1'45 in the second and 1*7 in 
the third, which is 1*25 in the longest ray. Pectoral short, the first 
ray longest, extending to above the last anal spine ; detached pec- 
toral ray about one third the length of the first ray ; base of fin 4*7 
in its length. Ventral large, 1/55 in the pectoral. 
G-ill-rakers 4 x 10, the longest 1*75 in the eye-diameter. 
Coloration {fide De Vis). — " A broadly white-edged black 
blotch between the ninth and twelfth spines of the dorsal ; top of 
the webs between the first two spines also black. Upper surface of 
the snout, a broad band across the occiput, a narrow curved band 
from the snout through the edge (? eye) to the base of the oper- 
cular spine, two large blotches on the upper part of the trunk 
connected and apparently traversed by three longitudinal bands, 
two horizontal bands on the soft dorsal, three vertical bands on the 
caudal, and the lower third of the pectoral black."
