Seas, and specimens have been found on the east coast of 

 England. 



6. Eschricht's Dolphin {Electra acuta), the White-sided Bottle- 

 nose [Leucopleurus arclicus), and (7) the White-beaked Bottle- 

 nose, natives of the Arctic Seas, have also been taken in the 

 Orkneys. 



The Black Fish (Pseudorca crassidens), natives of the North Sea, 

 have been found in a semi-fossil state in Lincolnshire. 



The Beluga or White Whale (Beluga catodon) and the Narwhal 

 are natives of the Arctic Seas, and sometimes occur on the coast of 

 Scotland. 



The Killers [Orca) inhabit the Arctic Seas, but they often come 

 to the south, even to the British Channel. These species are 

 said to live as far south as the Mediterranean Sea, but it is to 

 be determined if those of the north and of the south are the same 

 species. 



The Ziphins {Ziphius Sowerbieusis) has been so little observed 

 that it is difficult to determine its native country. It may be a 

 native of the .\tlantic on the west coast of Ireland, for that is the 

 district where it has been observed most frequently, but as yet 

 only males. Single individuals have been obtained in the North 

 of Scotland, on the coasts of Belgium and of France : the two latter 

 were females. 



II. Species that live in the southern part of the Atlantic or . 

 Mediterranean. Individuals sometimes wander north to the British 

 Channel and even to the North Sea : — 



The Grampus {Grampus Cuvierii). The Dolphin [Delphinus 

 delphis and Petorrhijnchtis cavirostris). 



III. Species that inhabit the tropical seas of both hemispheres, 

 and wander occasionally both to the norlh and to the south, to 

 their own destruction, as for example: — 



The Sperm Whale {Catodon macrocephalus), of which a single 

 specimen sometimes occurs in the Norlh of Scotland, probably 

 carried there by the Gulf Stream. Others have occurred in the 

 British Channel, &c.
