Habits. In appearance the long-finned 

 Squid differs little from the short-finned, the 

 most marked difference being indicated by 

 their names. In L. Fealei, the caudal fin ex- 

 tends over one half the length of the body, 

 clearly distinguishing it from 0. illecebrosa, in 

 which it is not more than two-fifths of that 

 length. The "pen" in the former is much 

 broader than in the latter, The eggs are laid 

 in gelatinous capsules, attached to some sup- 

 port. 



Economics. It is of precisely the 

 same use to man as the last species, 

 though from its more southern range, it 

 is little used for bait. It is the common 

 Squid south of Cape Cod. It has been 

 tried as food by the New York Ichthyo- 

 phagous Club, and pronounced "rather 

 tasteless."
