Largest specimen observed, 31 inches; female mature at a length of 14 inches. Head well proportioned in its shape, and of moderate size when compared with the body, but large in mature males ; body stout; hinder part of the tail rather short. The posterior point of jimction of operculum and suboperculum is nearer to the lower anterior angle of the suboperculum than to the upper end of the gill-opening. Prce- operculum crescent-shaped, the hinder and lower margins passing into each other ivithout forming an angle. Snout conical, much produced in the male sex, in which, during the spawning- season, a mandibulary hook is deve- loped. MaxUlary much longer than the snout, generally curved, solid, but rather narrow; in specimens 18inches long it extends to the vertical fi'om the hind margin of the eye, and much be- yond it in adult males. Teeth strong : the head of the vomer small, triangular, broader than long, toothless ; the body of this bone armed with a double or zig- zag series of teeth, the teeth being alternately placed, forming nearly a single series behind; they are per- sistent throughout life. Pins rather short, and obtuse; the length of the pectoral is one-half or rather less than one-half of the distance of its base from that of the ventral. The caudal fin is perfectly truncate in specimens 18 inches long, and in old individuals rather convex. There are from thirteen to sixteen scales in a transverse series descending from beh
