Note. — It seems quite evident that this large form or species is the same as the one described by 

 Gunnerus at the above-cited place, partly from its size, and partly from the fact, that it is well known 

 by the fishermen on the western coast of Norway, under the names of " Stour-Wagn," " Stour- 

 Henning," and " Stour-Hynning," mentioned by Gunnerus, and is distinguished by them from the 

 smaller species, which also is well known by them, and is oftener caught. The fishermen distinguish 

 this species particularly by its larger size, and its higher dorsal fin projecting out of the water like a 

 stake. Dr. J. Korea, of Bergen, who has had the opportunity of obtaining correct information about 

 this, and of closely observing the smaller species, first called my attention to the probability of the 

 Stour-Hynning being a different species from the Delphinus orca described by Schlegel. It is however 

 very apparent, that the species of this part of the genus Orca, as here described, or of Gray's Orca, 

 approach each other very closely. The following desci'iption of the dorsal fin given by Gunnerus, 

 and based upon a statement of Captain Coldevin: "i Steden for Ryg-Finde har en Stage, som 

 paa Norsk kaldes Stor eller Stour, og hvoraf Fisken har faat det Navn : Stour-Wagn eller Stour- 

 Henning. Denne ar af Been, 3 Alen boj. overtrukket med Skind, flad paa Siderne, bredere ved 

 lloden, og bliver alt smalere og smalere, ligesom et Sverd, dog noget budt i Enden," is partly 

 unnatural and erroneous. It is evident from this, however, that it has a very high dorsal fin, and that 

 its name is founded upon the form of this part. I have selected the specific name given by Lacépede, 

 as being the first that with any certainty corresponds with this species, although he repeats the old errors 

 and exaggerations, and partly seems to have confounded it with the D. orca, which he had previously 

 described. As Hunter has not given a very minute description, and in describing the colour of the 

 upper part of the body does not mention the white spot on the neck, it is not quite certain that he had 

 this species before him, although the considerable dimensions (24 English feet in length) make it 

 probable. All later authors have mixed the two forms, and could therefore not be mentioned in tlie 

 synonymy. The skeleton that I had an opportunity of examining was from the specimen that was 



^ I have unfortunately not had an opportunity of gaining information from Bonnaterre's Cetologie 

 of his Dauphin d'Anderson.
