BLACK FISH. 289 



THE JBLACK-FISII. GENUS GLOBICEPIIALUS. 

 Glohicephala^ Lesson, N. Tabl. Regne Animal Mamm. p. 200 

 (1840). 



General form of skull somewhat as in Orca^ but the fore part 

 of the head high and rounded, owing to the pre ence of a mass 

 of blubber; teeth, small, conical, curved, and sharp, forming 

 from eight to twelve pairs, which are confined to the anterior 

 half of the jaws, in old age blunt, and sometimes wanting ; 

 flippers very long and narrow ; back-fin short and triangular 

 the height being much less than the basal length. 



As in the case of Orca, it is very doubtful whether there is 

 more than a single ex'sting representative of this genus.
