The anus is located immediately in advance of the origin of the anal fin, somewhat farther forward than in C. quincunciatus, and much farther forward than in argentatus; it lies below the posterior half of the interdorsal space; the distance from the center of the anus to the base of the outer ventral ray is contained ( to ) times in the head; the distance between the ventral fin and the isthmus (at the front of the scaled area), is contained ( to ) times in the head; the total distance, from the anus to the isthmus, ( to ) times. As in argentatus and quincunciatus, the anterior lobe of the gland-like body in the abdominal wall is sup- ported by a slender rod connected with the joined ends of the two pairs of arms of the pubic bones.
