 tinguished by many important characters, and it may prove 

 necessary in the future to rank them as sub-orders.

 Stebbing. Family Tanaidae. Tanais, Audouin and Mihie-Edwards ;

 part, with the Tanaidacea. See especially those of Beddard, Delage, Hansen 

 (Plankton Expedition), Norman and Stebbing, Richardson, Sars, and Spence
