This animal ia gregarious in its habits, being very rarely seen alone, 

 and is observed to be a constant attendant at such places where 

 mackerel, pilchards, and other fish abound. It is swift and voracious, 

 and so eager in the pursuit of its prey that it is frequently found en- 

 tangled in the fishermen's nets. 2 The beak, which is characteristic of 

 the group, is flattened and elongated, and from this peculiar form, it ia 

 called by the French, " Goose-bill and sea-goose." The English 

 sailors, however, know this and similar animals by the name of " bottle- 

 noses" or " flounder-heads," and not by that of Dolphin? 



Considerable doubt is entertained among naturalists, whether the 

 Delphinus delphis of the European coast, and certain dolphins inhabit- 

 ing the Southern Seas, are to be regarded as the same species. Possibly

s The dolphin of sailors is a true fish, the Coryphsem hippuris, about five feet long, 

 and celebrated for the eternal war it wages against flying-fish, and for the surprising 

 changes of colour, when expiring.
