Octopodidae 



Polypus vulgaris (Lam.). Occ. specimens only were 

 taken on the S. coast until 1900, during the 

 summer of which it became exceedingly plen- 

 tiful all along the coast. In Sept. the depre- 

 dations of the octopus caused large numbers of 

 crabs (Cancer pagurus) 5 in. to 7 in. across to 

 seek shelter between tidemarks in Plymouth 

 Sound, and practically cleared the Sound of 

 swimming crabs (Portunus depurator). Not 

 content with the free crabs the octopus paid 

 visits to the crab-pots, killing large numbers of 

 crabs and lobsters, as the following, which re- 

 presents the total catch of an average of 30 

 crab pots per day for 6 days in Plymouth Sound 

 (Oct. 1 5-20), will show : Crabs living, 3 ; 

 lobsters living, 1 5 ; octopus, 64. Crabs dead, 

 44; lobsters dead, 41. In Nov. the trawlers 

 were catching large quantities of octopus, up 

 to 100 per haul, 5 miles off Plymouth, and 

 20 m. S.S.E. oi Berry Hd. In 1901 the quan- 

 tities of octopus caught were practically normal
