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. 
Tn 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
