Suborder Scombroidea 

 Family SCOMBRIDAE 



The Venezuelan material of this family is so limited that I have not 

 attempted to make a key. Instead I am copying the "Key to the 

 Genera" which appears on pages 307-308, part I, of Meek and Hilde- 

 brand's "The Marine Fishes of Panama." This key includes those 

 genera of scombroid fishes most likely to be found along the coast of 

 Venezuela.
