LXIIL — Notes on British Copepoda : Change of Names. 

 By Thomas Scott, LL.D., F.L.S. 



In the ' Fifteenth Annual Report of the Fishery Board for 

 Scotland' (1897), part iii. p. 150, I described a species 

 belonging to the Copepoda under the name of Delavalia 

 mimica ; but though it exhibited a close affinity with the 

 genus Delavalia, especially in the structure of the mandibles 

 and of the fifth pair of thoracic feet, the structure of the 

 first pair more nearly resembled those o£ Nitocra or Ameiraj 

 the inner branches of that pair being composed of three 

 instead of two joints. In my remarks on the species I 

 referred to this difference ; but because the species had such 

 a general resemblance to Delavalia it was provisionally 

 ascribed to that genus. 



During recent 3'ears many specimens of this species, botli 

 fium the Scottish and English coasts, have been examined,
