EEPORT ON THE CEPHALOPODA. 91 



It will probably prove to be identical with some of the forms from the same region which 

 have hitherto been insufficiently described.

It is not a little interesting that this species should have been found on the north- 

 west coast of Europe, whither so many species which have been described from the coast 

 of America seem to extend ; another instance will be found in the ease of Verrill's 

 Octopus hairdii, which has been found by Sars off the Norwegian coast, and by the 

 British expeditions in the Fseroe Channel (see next species). 



The hectocotylised arm, which Verrill's specimens being females did not show, closely 

 resembles that of Octopus arcticus, Prosch, and agrees very well with the figure given 

 by Steenstrup,^ except that it is rather more pointed at the tip.
