This genus is closely allied to Bairdiella in nearly all respects, but with 

 the preopercle entire and unarmed as in Larimus. The species difler 

 considerabljr among themselves, and they form with Larimus and. Odoiiios- 

 cion an almost continuous series. American. (Diminutive of Corvus, 

 crow, as is also the name Corrina, applied by the Latin races to fishes of 

 this group, perhaps in allusion to their croaking noise produced by the 

 complicated air bladder.)
