Part III. — Twenty-second Annual Report 



genus of Coleoptera, its use by nie for a germs of Copepoda must therefore 

 lapse, and the name I propose to substitute for it is Jeanella, the diminu- 

 tive of the proper name Jean. 



(b) Genus Paranthessius, T. Scott, Twenty-first Report of the Fishery 

 Board for Scotland (1903), Pt. III., p. 120. This name has already 

 been used by Professor Claus for a genus of Copepoda different from that 

 described in the Report mentioned, and it must therefore be replaced by 

 another, and the name I propose to substitute for it is Heteranthessius.
