440 BULLETIN OF THE UNITED STATES FISH COMMISSION. 
Habitat. — W arm seas ; north to Newfoundland and Japan. The speci- 
men examined by us is from Venice. 
Etymology: tunny — thynnus. 
This species, according to Dr. Gill, reaches an average weight of 200 
pounds, and a length of 8 to 10 feet. Specimens of 1,500 pounds weight 
are, however, on record. It is scarce off our coasts, but so abundant 
in Southern Europe as to be the object of very extensive fisheries. Its 
flesh is rather coarse, and not of superior flavor.
