This skull, which has all the appearance of being that of a full- 

 grown animal, is just one quarter the length and breadth of the skull 

 of the adult common Killer {Orca gladiator). 



" In the ' Zoology of the Erebus and Terror," Dr. Gray has figured 

 and desciibed a skull (in the British Museum, locality unknown) 

 under the name of Orca intermedia. This is evidently that of a very 

 young individual, probably of one of the above-mentioned large 

 siJecies. At all events the number of the teeth (j-j-) and the form 

 of the premaxillaries distinguish it from the Tasmanian skulls." — 

 Floiver, P. Z. S. 1864. 



3. Orca Capensis. The Cajje Killer. 



Skull flattish above, rather concave in the middle before the blow- 

 hole. Nose rather convex on the side, rather tapering in front.

 concave on each side for the reception of the teeth of the opposite

 rounded. Intermaxillaries rather dilated, and broader over the 

 front of the nose, contracted behind.
