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

 424," inserting instead ^'Mcgalops aflanfieu.^ 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 G feet, and is known as "Grande Ecaille."
