ARGENTINA GEORGEI, NEW SPECIES 



Figures 2, 3, 4, 5, 8, 9, IOC, 11 



Diagnosis 



This species can be separated from A. sphyraena 

 and silus by its smooth instead of spiny scales and 

 by its five rather than six branchiostegals. It dif- 

 fers from siliis, sialis, aliceae, and elongata in hav- 

 ing 6 (occasionally 7) gill rakers on the lower arm 

 of the first arch — the four species listed above have 

 8 to 21. It differs in gill raker count from A. 

 brucei, which has 7 (occasionally 6) rakers; also 

 georgei has 47 to 50 vertebrae, brucei has 44 to 46. 

 It differs from euchus in having 12 to 14 ventral 

 rays rather than 10 or 11. It differs from 

 sphyraena, sialis., elongata, and a.usiraliae in hav- 

 ing 16 to 19 pectoral rays rather than 11 to 16. It 

 differs from kagoshimae in having vertebrae 

 usually less than 50 rather than usually more than 

 50 ; pectoral rays 16 to 19 rather than usually less 

 than 17 ; ventral rays usually 13 or 14 rather than 

 11 or 12. It differs from striata in lacking silvery 

 pigment on the swimbladder ; in having anal rays 

 usually 10 or 11 rather than 12 or 13, pectoral rays 

 usually 17 or 18 rather than 19 or 20, and caudal 

 peduncle depth in head length usually more than 

 6 rather than 6 or less. It differs from stewarti in 

 having 47 to 50 vertebrae rather than 52 or 53, in
