ABSTRACT 



Four new species of the genus Argentina are de- 

 scribed, three from the western Atlantic and one from 

 Peru. Range extensions are presented for A. euchus from 

 the western Indian Ocean and A. sialis from the north- 

 eastern Pacific. Speciation in the genus is discussed, 

 and a l(ey is presented to the 12 species recognized. 



Pigmentation of the swimbladder and its significance 

 as a systematic character are discussed. 



A new species of Glossanodon from the western Indian 

 Ocean is described, and additional material of G. polli 

 from the tropical eastern Atlantic is noted. 



Argentinine fishes are taken in commercial 

 quantities in the temperate western North Atlantic 

 (Emery and McCracken, 1966) and are forage 

 fishes in Australia (Fairbi-idge, 1951). Species 

 found in tropical waters are usually associated 

 with shrimp grounds and are available to shrimp 

 fishing gear. This paper su^jplements the revision 

 of argentinine fishes published by Cohen in 1958. 

 Since then, additional material has accumulated 

 comprising undescribed species, additional ma- 

 terial of poorly known forms, and range exten- 

 sions. In this paper we reassess the status of pop- 

 ulations in the genus Argentina. We discuss 

 speciation, comment on swimbladders, and de- 

 scribe one new species from Peru and three from 

 the tropical western Atlantic. Range extensions 

 are recorded for A. euchxi^ from the western In- 

 dian Ocean and A. sialis from the northeastern 

 Pacific. A new species of Glossanodon from the 

 western Indian Ocean is described, and additional 

 material of G. polli from tropical West Africa is 

 noted.
