 {Scomber crumenophthalmus Bloch). 



« The genus Selar Bleeker was based on four species, the first named being Caranx hasselti, which is a 

 species of the modern t'enus Atule Jordan and Jordan. It was first restricted to Scomber boops Bleeker, a 

 species of Trachurops; but this restriction can not stand as boops was not mentioned by Bleeker in connec- 

 tion with Selar: Caranx liasseUi=affinis of the south Pacific must therefore be the type of Selar.
