Gen. ^TIDIUS, Brady. 

 1883. ^tidius, Brady, Challenger Copepoda, Eeports, vol. viii., p. 75. 

 Stnce Brady derives this name from cuncevc: — an eaglet — he 

 ought to have written it, as was subsequently but unlawfully 

 done in Das Tierreich, Aetideus. As will be seen, it has 

 received three other forms, all incorrect as well as unlawful.

pis. 13, 14. 

 In dealing with Boeck's species Sars hints at the possibility 

 that Boeck, Brady, and Giesbrecht may have had three 

 distinct forms in view, though he is at the same time 

 uncertain whether the three do not all belong together.
