Body moderately elongate, the back rather strongly arched, the protile rising in a regular curve from tip of snout to origin of dorsal fin, thence descending in a broader curve to caudal peduncle; ventral outline less convex: head pointed, the lips thick, jaws subequal, or the lower slightly the shorter: premaxillar}' strongly protractile: exposed portion of maxillary l)road, its greatest width half its length, its posterior edge slightly concave: prcopercle entire; interorbital liroad; premaxillary groove narrow, completely scaled except a small circular area posteriorly above anterior margin of orbit; caudal peduncle rather deep, its greatest depth greater than diameter of eye, or 3 times its least width. Scales large, thin, and firm; origin of dorsal fin over of pectoral, the second spine slender, curved, and lengthened, its length greater than half that of head; dorsal rays short; second anal spine shorter and scarcely larger than the third, its length L4 in eye; dorsal and anal fins each with a high, scaly sheath; caudal fin thickly covered with fine scales: peritoneum dusky: second interhsemal spine long and slender: posterior end of air-bladder bifid, ending in 2 long slender horns which fit alongside of second interhi*mal. Color in spirits, silvery white, the back and upper part of side .showing faint dark lines along the middle of each row of scales parallel with the back; tip of spinous dorsal dark, fins otherwise unmarked. This species is close to X. iapas, from which it difl'ers chiefly in having the pi'emaxillary groove scaled, the eye larger, the interorbital space broader, and the second anal spine Fig. 8.—Xt/st^iiia haco/tfii.^ EviTiiiiinn tt Sy two specimens—one (no. .3410) from Bacon, and the other (no. 3377) from Jolo.
