423 THE ZOOLOGIST. 



whole uiDper side of the body, and both upper and lower parts of 

 the head, jet-black. The under side towards the tail end is also 

 black ; the remaining portions varied in the three males I 

 examined. 



In the specimen about forty feet long (Aug. 23rd) the throat, 

 with the furrows and nearly the whole of the under side, was 

 white; part of the under side of the flukes white; the flukes were 

 about 15 ft. across, narrow, notched along the free edge. The 

 flippers measured lift. 4 in. to the head of the humerus; 

 breadth at their broadest projection 3 ft. 2 in. ; opposite axilla 

 2 ft. 1 in. The flippers were black on the outer side, white on 

 the inner, the black extending round the edge to the inner side, 

 with an occasional blotch of black, and two or three black rings 

 — looking as if the outer side had been painted black, and the 

 colour brought well round the edge to prevent the white showing 

 from in front. 



In the specimen about forty-four feet long (the one caught 

 during my cruise) the under side was entirely black, except two 

 white or marbled patches on the chest, just aft of the flippers, 

 and one or two tiny white spots not bigger than crown-pieces 

 about the belly ; half the lip of the navel was white. Flippers 

 all white on the inner side; proximal quarter of the outside 

 black, but the black stopping short of the anterior margin. 

 Length from blowholes to end of nose, 7 ft. 10 in. Greatest 

 width of skull, a few inches anterior to blowholes, at the zygo- 

 matic portion of the frontal bones, 5 ft. 4 in. Length of flipper, 

 including humerus, 15 ft, (about 13 ft. 9 in., measured to the skin 

 at axilla) ; width of flipper at proximal notch, 3 ft. 7 in. ; width 

 of flipper at biggest notch more than half-way down, 3 ft. 1 in. 

 Height of tin at after end, 9 in. The flukes having been cut off, 

 not to be in the way in towing, I could not measure their width, 

 but from fore to aft at the middle line they measured 3 ft. 7 in. 



The specimen about thirty feet long was almost entirely black 

 on the under side, flippers quite white on the under side, and 

 only black on the upper side a little way down from proximal 

 end. This species may be immediately identified by the remark- 

 ably long, unnatural-looking flippers; they are not distinctly 

 curved or scimitar- shaped, as in the Korquals, but are nearly 

 straight and deeply notched or undulated along the anterior 

 margin, and to a slight extent on part of the posterior also.
