 this genus should stand as

Page 262. Instead of Megalops thrissoides read : 

 436. UI. atlanticus C. & V. 



And erase the synonym " Clupea thrissoides Bloch & Schneider, 1801, 

 424," inserting instead "Mcgalops atlanticus C. & V. xix, 398." 



Clupea thrissoides Bloch & Schneider is based on Broussonet's descrip- 

 tion of his Clupea cyprinoides, which is the East Indian Megalops cypri- 

 noides (Brouss.) Bleek. On our Gulf coast, Megalops atlanticus reaches 

 a length of about C feet, and is known as "Grande Ecaille."
