Anus situated in the front of the cutaneous part of the expansive, boat-shaped mandible. Dorsal thong black above, flesh-coloured on the under surface, with black points on its sides,* and reaching to within an inch of the caudal fin. Pectoral equal in length to the orifice of the mouth. Anal lin commencing before the gill-opening, and ex- tending backwards to the caudal fin. Lateral line protected by keeled scales, with notched points. The other scales are pretty smooth and moderately large. Head bluish-black, with lighter, almost white, upper lip and mandible. Back dark brown, dotted with dark spots near the anal fin.

This is the longest and most compressed species. In the upper jaw there are two clusters of teeth, which are prolonged each into two rows. The eyes are situated between the second and last third parts of the length of the head. Their distance from one another equals two diameters of the orbit. Behind the anal fin the tail is sharply keeled. Lateral line keeled by the arrangement of large scales that accompany it. On the back and over the anal fin the scales are small. Anus situated beneath the eyes. Between * Cuvier was the first to make the erroneous assertion that this dorsal thong is a detached cutaneous muscle of the tail. More lately Professor Keinhardt supports this opinion in Wiegmaa's .Journal for 1854, p. 183, and remarks that the thong
