RORQUALS, OR FINNERS. 271 



Collett in the Norwegian seas, it feeds almost exclusively on 

 small crustaceans, and never touches fish.

Characters. Size small; back-fin (as in the last species) 

 relatively tall, and placed far forwards ; colour of upper-parts 

 greyish-black, with the exception of a broad white band across 

 the flippers; under-parts, with the exception of the lower 

 surface of the flukes, which is coloured like the back, but 

 including the inferior aspect of the flippers, white ; whale-bone 

 yellowish-white. Total length of adult about 30 feet, or 

 less. 



Distribution. Typically, the Lesser Rorqual, or, as it is often 

 called, the Pike-Whale, is an inhabitant of the North Atlantic, 

 ranging as far north as Davis' Straits, and often found on the 

 Scandinavian coasts, but seldom entering the Mediterranean.

 form in the Pacific, which in our own opinion is probably 

 specifically the same. 



To the British coasts this Rorqual is a comparatively 

 common visitor, and there are several examples in our 

 Museums which have been taken in our own seas. It will be

 land; but we may mention that one was taken in Cornwall in
