 Copepoden der Kieler Foehrde, p. loS. 



The reference of this species to Cyclops brevicornis Miiller — 

 until recently adopted by most authors — was, to say the least, 

 a very doubtful one. It seems best, therefore, to use the new 

 specific name proposed by Giesbrecht. 



T. discipes is to be found plentifully during the summer 

 months in the brackish pools of almost all estuaries and salt- 

 marshes. N.D.
