Although the right whale of the southern oceans and that of 

 the North Pacific are believed to be probably racially distinct 

 from the North Atlantic right whale, the diagnostic characters, 

 if any, are not well made out. Lonnberg (1923) has compared 

 skeletons of the latter with a skeleton of the southern right 

 whale from South Georgia and regards the differences as of 

 taxonomic importance. Further comparisons in series are 

 needed to establish the validity of the supposed races or species. 

 Since all are essentially similar in general appearance, they 

 may be considered together here, as separate populations. 



The right whales are of stout, massive proportions, the head 

 forming about a quarter of the total length and having the 

 rostrum much narrowed and strongly arched to accommodate
