Colour similar to that of the Orca gladiator. 



Dr. Gray observes, in page 285, " the examination of the skeleton, and 

 especially of the skull, shows that they (Orca gladiator of the British 

 coast, and Orca capensis) are quite distinct"; whereas Professor Owen, 

 in his elaborate analysis of the same animals, concludes his strictures 

 with the equally strong opinion : " The slight differences noticeable in 

 the skull chiefly depend on the muscular attachment, and are of a kind 

 to characterize varieties — not to establish specific distinctions." As I 

 entertain no belief in the theory of limited locality, particularly when 

 applied to such powerful beiugs, I adopt, without hesitation, the view 

 suggested by Prof. Owen, and consider the 0. capensis as a variety only.
