 probably in some cases not so fresh as those I saw in Newfoundland ; hence the 

 frequent use of the term "grayish black" (graasorte). 



DORSAL FIN. 



In Sars's account of the "Blaahval" the variations in the shape of the dorsal 

 fin are described as follows: (78, 237 ; sep., 13) : 



" Not less characteristic of this species than the pectoral fins is the dorsal fin, 

 which with its unusually small size and position far backward, or at the beginning 

 of the last fourth of the total length and much back of the vertical line drawn 

 through the anus, is at once distinguished from those of all other known whalebone 

 whales. In its form it is at the same time the part which, as it appears, undergoes
