 the vent.

The name of Germon has been applied to more than one 

 species, but we confine it to that to which in our opinion it 

 more properly belongs, and which is common and abundant on 

 the south coasts of Europe; as well within the Straits of 

 Gibraltar as without; where it has many of the habits of the 

 Tunny, and is equally the object of valuable fisheries. There 

 is no doubt indeed that a portion of the history of the Tunny, 

 as it has been handed down from ancient writers, applies to 

 this as to the Bonito and kindred species; so that long obser- 

 vation will be required before we can assign to each of them 

 its separate portion. It appears however that the Germon 

 passes through a less extensive range than the Tunny, at least
