Fig. 19.

Specific characters.—General profile elliptical, height of body nearly one-quarter its length, breadth about half the height.

Head laterally compressed, somewhat flattened on top, the nose horizontally rounded, but laterally pointed. Base of tail vertically compressed, one-third broader than it is high. Head half the length of body, its height behind orbit equal to half its length. Diameter of orbit one-sixth the length of head, its form obliquely oval. Jaws equal, gape of mouth one-third the length of head.

Pectoral fin, arising at middle of vertical of side, nearly half the total length, its width at base one-eighth of its length, but suddenly narrowing to one-fifteenth, which width it retains nearly to the end, its outer third curving gradually downward, and becoming pointed. First dorsal commencing directly above pectoral, its length nearly one-fourth of total length, and its height in front two-fifths of its length. Spines rapidly decreasing in length from the first to the eighth, the next six about equal, and a third of the first, the last one very short. Second dorsal immediately behind the first and a little higher, triangular, nearly one-third higher than long, its base lengthened posteriorly, and one-third the length of the first dorsal. Finlets eight above and eight below, acutely triangular, those near the middle a little larger.

Caudal large, its lobes equal, their length three times their width, and one-third that of the pectoral; posterior outline arcuately concave, with slightly widened lobes near the middle.

Anal opposite end of second dorsal, similar to it in form, but smaller, and about twice as high as long, its position half way between the ventrals and caudal. Its first spine is only about one-third as long as the second, which is two-thirds the height of fin; both concealed by the skin.

Ventrals arising opposite second dorsal spine, about twice as high as wide, their inner margin with a small pointed lobe.
