32 ONYCHOTEUTHID^. 



These animals are solitary in habit, frequenting the open sea, 

 and especially banks of gulf-weed. Some of the species have an 

 immense geographical distribution ; as 0. Banksii^ from the 

 Arctic Ocean to the Cape of Good Hope and Indian Ocean. The 

 peculiar arrangement of suckers, forming a cii'cle at the base of 

 each tentacular club, enabling the animal to use the two clubs in 

 conjunction when necessar}^, give an immense increase of power. 

 They suggested the obstetric forceps of Professor Simpson.
