Atheresthes and Reinhardtius. The dorsal begins over the posterior 

 part of the eye, and the teeth are rather small and close together. 



The fin ra3's are in relatively small numbers (D. 74, A. 54), and the 

 vertebra? also (11 + 29), characters which separate this genus from 

 Reinhardtius. The caudal fin is truncate and not lunate. Okhotsk Sea.
