also rounds down on the lower part of the "small," nearly midway between the 
hump and caudal. Its under jaw extends forward considerably beyond the upper 
one. All these combined characteristics impress the observer with the idea of an 
animal of abnormal proportions. The top of its head is dotted with irregular, 
rounded bunches, which rise about one inch above the surface, each covering nearly 
four square inches of space. 
The following measurements and memoranda of a male Humpback were taken 
by Captain F. S. Rediield, of the whaling and trading brig Manuella, while cruising 
in Behring Sea, September 17th, 1866:
