Integument.-In the dorsal region the integument was of a uniform black colour, which was continued back over the dorsal fin and upper surface of the tail, and forwards over the forehead. At a short distance from the mouth this colour stopped abruptly with a sharp outline, giving place over the snout to a creamy yellow colour, this patch being deepest in front (2 inches), and gradually narrowing towards the angles of the mouth on each side, near which it ended. In front, in the middle line, a process of creamy yellow, about the breadth of the point of the little finger, and about \ an inch long, passed upwards from the white of the snout into the forehead. The skin of the mandible, throat, and belly was creamy white. The flippers were jet-black, aud the tail on its under surface was of a blackish slate-colour. The black colour of the dorsum was not continued uniformly over the sides ; but was interrupted by three white patches. Moreover the tint of black on the sides was not so deep as that over the back, being more slate-coloured. Of the white patches, one of large size (10 in. by 6 in.) was situated upon the neck, in front and above the level of the flipper. It was irregular in its outline, more or less completely divided into an upper and a lower portion by a stripe of slate-colour, and interrupted here and there by sharply defined deep-black lines and spots of small size.
