Genus DELPHINUS : DelpUnus. — This includes not only the Common Dolphin, but many 
species similar to it : maritime people give to these various names, as Bottle-noses, Bottle-heads, 
Flounder-heads, &c.; the name Dolphin they usually apply to a totally diff"erent species, the 
Coryphoena hippurus, which changes color in dying. The Common Dolphin, D. delphis, abounds 
in all the seas of the northern hemisphere. It measures six or eight feet in length, and is one of 
the most active species of the family. It is noted for its fondness for accompanying ships in con- 
siderable flocks, sporting upon the surface of the water as if for the delight of the beholders. It 
is said that in these gambols individuals have been known to leap out of the water to such a 
height as to fall upon the deck of a ship. The ancients were well acquainted with the sportive 
habits of the dolphin, and regarded it as the special friend of man. It was one of this species

waves. Other species are as follows :
