Skull : Length, entire 14 



Length of nose 7 



Length of teeth-line 5 G 



Length of lower jaw 11 



Breadth at orbit 8 3 



Breadth at notch 4 6 



Breadth at middle of beak 9 



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 tjlaf/iator). 



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

 and described 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 largo 

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

 of the premaxillarics chstinguish it from the Tasmanian skulls." —
