The usual spots under preopercular margin and on gill membranes. A small humeral spot present at upper end of opercular cleft. Suprapectoral on the first scale below lateral fine, its distance from lateral line one-fourth its distance from pectoral fin; upper infrapectoral above middle of pectoral base but below its uppermost rays; lower infrapectoral vertically below the upper, slightly in advance of a fine joining the other two. Thoracics 5, the fourth elevated, on a level with upper pectoral rays or slightly above them, a trifle behind vertical from third thoracics; first, second, third, and fifth pairs of thoracics forming gently diverging lines, the fifth less widely separated than in L. regale, not opposite the outer ventral rays; second and fourth thoracic interspaces equal, the first one-third longer. Supraventral vertically above ventral base, midway between ventral base and lateral line, very little above the line joining the two lower supraanals. Ventrals 4, the first pair nearest the median line, at base of inner ventral rays, those of second pair most widely separated, forming with the third and fourth pairs lines gently converging to the sides of the vent. Supraanals angulated, the first and second in a line parallel with lateral line, a little nearer the ventral outline than the lateral line, the first over or slightly in advance of the third ventral spot, the second vertically above the first anal ray; third supraanal in contact with the lateral line, above the interspace between first and second anals. Anteroanals 8, the first 7 forming a weakly curved line with the concavity downwar...
