SkuU : Length, entire 14 



Length of nose 7 



Length of teeth-line 5 6 



Length of lower jaw 11 



Breadth at orbit 8 3 



Breadth at notch 4 6 



Breadth at middle of beak 9 



This skuU, 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 described a skull (in the British Museum, locality unknown) 

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

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

 species. At all events the number of the teeth (-fj-) and the form 

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

 Flower, P. Z. S. 1864. 



3. Orca Capensis. The Cape Killer. 



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

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

 Teeth -l-|, side upper very large, thick, nearly to the preorbital notch, 

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

 jaw ; the front iipper small, acute ; front lower large, worn down, 

 rounded. IntermaxUlaries rather dilated, and broader over the 

 front of the nose, contracted behind.
