seems as near T.fucensis as T. chalcogramma. Its rays * arc D. 11-16-17; 

 A. 18-17; ventrals reaching f distance to vent; iuterorbital space wider 

 than eye; coloration dark. But its body is as slender as in T.chalco- 

 gramma. (fucencis, from the straits of Juan de Fuca.)

This genus differs from the other codfishes in the structure of the trans- 

 verse processes of the vertebra, which are club-shaped, narrow at base, 

 but expanding distally into a rounded hollow bulb at their tips. Skeleton 

 otherwise essentially as in Hicrogadus, the skull similar. Small codfishes 

 of the Arctic seas. (eXeyiros, a social fish mentioned by Aristotle.)
