66 CYBIUM MACULATUM. 



Gmelin and Shaw have done no more than retain the name, and copy the de- 

 scription, of Linnseus. 



Dr. Mitchill observed this fish in the waters of New York, and, supposing it to 

 be an undescribed species of Scomber, he applied to it the specific name of plum- 

 beus, and gave a very good figure of it. 



Cuvier and Valenciennes have published the most accurate description of the 

 Skipjack, and cleared up the obscurity of its history.
