Dorsal profile of body slightly convex from tip of parieto-supraoccipital process to last dorsalfin ray, then slightly concave to adipose-fin spine and descending straight downwards from this point to caudal-fin base. Ventral profile of body slightly convex from isthmus to anal-fin origin, mainly in pectoral- and pelvic-girdle region. Profile markedly straight, ascending obliquely from first analfin ray to caudal-fin base. Body roughly triangular in cross section at pectoral girdle, gradually becoming more compressed toward caudal fin.
