1S8 ESCHRICHT ON THE NORTHERN SPECIES OF ORCA. 



dorsal fin like that of the " Stourvang" {Orca (jladiaior), but as he states expressly in his 

 letters that individuals were also found in the flock, with a lower and more curved 

 dorsal fin, it would seem that in this species, too, the dorsal fin has a different height and form 

 in the different sexes. 



Mr. IMiiller opened and examined the stomach of one of the killers stranded in Kollefjord, 

 and found in it the hairs and claws of seals as well as small white laminæ of whalebone, which 

 could scarcely have belonged to any other species of whale than the lesser Rorqual {Balænoptera 

 rostrata, Fbr. or B. minor, Knox). 



[Eschricht does not seem before his death to have chosen any name for the third northern 

 killer, at all events nothing was mentioned about this point in his manuscript; but 

 Professor Steenstrup, to whom the skeletons of the individuals stranded in Kollefjord had origi- 

 nally been sent by Mr. Miiller, with the information he was enabled to impart about them, 

 and from whom Eschricht received all these materials for his own use, has now designated 

 the new species by the certainly very appropriate name of Orca EschricJdii.
