A vertical line drawn so as to divide the animal into two equal 

 parts passed through the dorsal fin, dividing it unequally, 2 inches 

 of its base lying in front of the line and 8 inches behind it. 



Integument. — in the dorsal region the integument was of a uni- 

 form 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 narrow- 

 ing 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, and 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; hut 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 G 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 

 latl -colour, and interrupted lure and there by sharply defined deep- 

 black lines and spots of small size. A slender bar of slate-colour,
