Bossia, established by Owen, and named in honour of Sir 

 John Ross, differs from Sepiola in the head being separate 

 from the body, and the mantle free all round ; the suckers, 

 moreover, on the tentacular arms are in two rows. One 

 species inhabits the Mediterranean, two have been taken 

 on our coasts, one is from the North Sea, and another from 

 the Indian Ocean.
