Dorsal profile rising gently from tip of snout to origin of dorsal fin, then almost horizontal or sloping very gently ventrally to end of caudal peduncle. Ventral profile horizontal to anal-fin base, then sloping very gently dorsally to end of caudal peduncle. Caudal peduncle long slender and moderately compressed. Anus and urogenital openings located almost at level of line through posterior pelvic-fin margins. Skin smooth. Lateral line complete and midlateral. Vertebrae 26+14=40.</paragraph>
