Teeth, ^ to ^2, rarely , slightly curved at their tips. 

 Inhab. : North Sea. 



Colour, smooth and shining jet-black on the upper parts of the body, 

 somewhat paler underneath, relieved by a white streak from the throat 

 along the abdomen. The length varies from 6 to 26 feet ; the 

 pectoral fins are very long, 6 to 8 feet each, and narrow, being the 

 reverse to the exceedingly broad swimming paw of the O. gladiator. 



The food of the deductor is similar to that of the preceding animal, 

 namely, cuttle-fish, crustaceans and small fish ; and when the aliment is 

 plentiful, it becomes exceedingly fat, and affords a large quantity of 

 excellent and valuable oil. 



In their habits the members of this family appear to be the most 

 sociable of the cetacea, herding together in large flocks ; and in their 

 disposition very timid and wholly inoffensive. " In all instances on 

 record of their being discovered at sea, and hunted to land, the chase 

 has been free from danger, and a few frail boats and most ineffective 

 weapons, with shouts and noise in the water, were sufficient to drive 

 them from their native element to their destruction." 



1 globus, a globe, and Ke<aA^, head. 



2 deductor, a follower (when one is driven ashore the rest follow). 



3 From the scotch, caa, signifying to drive, being the ordinary method of their 

 capture, via., by driving them ashore.
