It has been ascertained, " 1st, that it is much more active than the 

 Greenland Whale, much quicker and more violent in its movements, 

 and accordingly both more difficult and dangerous to capture ; 2nd, 

 that it is smaller (it being, however, impossible to give an exact 

 statement of its length) and has much less blubber ; 3rd, that its 

 head is shorter, and that its whalebone is comparatively small and 

 scarcely more than half the length of that of the B. mysticetus ; 

 4th, that it is regularly infested with a cirriped belonging to the 

 genus Coronula, and that it belongs to the temperate North Atlantic 

 as exclusively as the B. mysticetus belongs to the icy sea." — Dr. 

 Brown, P. Z. S. 1868, p. 546. 



Dr. Brown says that barnacles are looked upon as a sign of age in 

 a "Whale ; and he considers that a considerable portion of the de- 

 scription of the nordcaper corresponds with what he has said of the 

 Spitzbergen whale (P. Z. S. 1868, p. 547).
