 utrinque quatvor longitiidinalibus nigricantibus. 



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, strongs 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 Fasciola 

 clctcata being often found in considerable numbers 

 in its stomach, and various kinds of Teenies and 

 A scar ides in the bowels.
