 names of Black Pollack, Blockin, and Grey-Lord. 



When detained and >vell fed in a salt-water pond, Coal- 

 fish acquire large size. " They were bold and familiar; 

 floating about slowly and majestically, till some food was 

 thrown to them ; this they seized voraciously, whether it

 hand." — Jesse's Gleanings.

 of the origin of the pectoral fin and before the line of the

 fins nearly parallel : the fleshy portion of the tail elongated ; 

 the rays forked : the ventral fins small ; and the rays of the 

 pectoral fin only extending as far as the line of the vent. 

 The fin-rays are —
