NO. 1 8 MENHADEN, GENUS BREVOORTIA HILDEBRAND 37 



Distribution. — B. gunteri is the counterpart in the Gulf of B. smithi 

 in the Atlantic, just as B. patronus in the Gulf is the counterpart of 

 B. tyrannus in the Atlantic. In each instance the range in geological 

 times very probably was continuous, but in due course it became dis- 

 continuous. At least at present menhaden quite surely do not occur 

 in southern Florida. Therefore, no intermingling can take place. 

 Under separation and under environmental differences minor changes 

 seem to have taken place. Although no specimens of B. gunteri from 

 Florida are included in the collections examined, I do not regard that 

 as evidence it does not occur there. For that matter, only a few speci- 

 mens of B. patronus from Florida are at hand. Yet menhaden are 

 numerous enough to supply a reduction plant at Port St. Joe, Fla. 

 Probably because menhaden are common, they have not been con- 

 sidered of much interest to collectors, and even if many examples were 

 taken, few were preserved. 



Range. — Known from the Gulf of Mexico, from Grand Isle, La., to 

 the mouth of the Rio Grande, Tex. Very probably occurring else- 

 where in the Gulf; generally not recognized by collectors. Usually 

 living in bays where the water runs low in salinity.
