General Catalogue of South African Crustacea. 543 



Edwards (Hist. Nat. Crust., vol. iii., p. 430), 1840, it should, 

 in my opinion, be modified as above. At this point the classifi- 

 cation turns from the Gymnoplea of Giesbrecht to his 

 Podoplea, of which I have given a summary in the Encyclo- 

 paedia Britannica, ed. 10, Suppl. vol. iv., art, Entomostraca, 

 1902. The difficulty of so defining the group that it may fit- 

 tingly embrace all the remaining families of the Copepoda, 

 has led authors to prefer the arrangement proposed by Sars in 

 his Crustacea of Norway, vol. iv., pt. 1, 1901, although at 

 present only two of his seven divisions, the Calanoida and 

 Harpactioida, have been worked out, each occupying a splen- 

 didly illustrated volume .

Giesbrecht suggests a family or sub-family Setellidae for 

 this genus. Sars would apparently include it in his family 

 EctinosomidsB (preferably Ectinosomatidae) .
