The validity of Cynoscion altipinnis (Steindachner), and Cyno- 

 scion perucmus (Tschudi), seems very questionable and we follow 

 Jordan and Eigenmann in placing them in the synonymy of this 

 species. Steindachner's original description of C. altipinnis is based 

 on a specimen 17.8 cm. (7") long, considerably smaller than those 

 described by Abbott, and as he himself states " the most important 

 difference (between the two) seems to lie in the lack of developed 

 opercular spines in analis^ while the other species {altipinnis) has 

 two quite strong spines." Steindachner ^ calls attention to the fact 

 that in a specimen of analis 21 cm. long the eye is 5 in head and in 

 individuals 32 cm. long it is contained 6 times. He also includes 

 Archoscion analis of Jordan and Eigenmann in his synonjmiy, which 

 by Abbott has been included in the synonymy of altipinnis, originally 

 described by Steindachner and later placed by him in synonymy of 

 analis. Tschudi's description of peruanus is based on a large indi- 

 vidual (1' 3") and agrees closelj?' with the descriptions of analis.
