Silvery" Mackrel, with blueish back, and body marked on each 

 side by four longitudinal blackish streaks. 



Scomber Pelamis. Lin. 



GENERAL appearance that of the Tunny, but 

 more slender : colour the same as in the Tunny, 

 but distinguished by four linear stripes on each 

 side beneath the lateral line : scales very small : 

 ventral fins long and narrow, and occasionally re- 

 ceived, as in several others of this genus, into a kind 

 of channel beneath : first dorsal fin falciform, and 

 depressed at pleasure into a fossule, so as to be 

 quite concealed : tail strongly lunated: finlets eight 

 above, and seven below; and on each side the base 

 a coriaceous lamina: native of the Atlantic and 

 tropical seas, and a very active, strong^ and voraci- 

 ous species, persecuting flying-fishes, &c. in the 

 manner of the Tunny, and is itself tormented by 

 several species of intestinal worms ; the Fasdola 

 clavata being often found in considerable numbers 

 in its stomach, and various kinds of Tceniff and 

 Ascarides in the bowels.
