cordingly Beneden's genus name must be substituted for that of 

 Milne Edwards, and the type of the genus becomes Congericola pal- 

 lida Beneden. 



Nordmann in 1832 described" a genus and species called EpachtJisii 

 parad.oxus. The next year Burmeister " showed that Normann's 

 genus was a synonym of Lemanthropus. 



In January, 1898, Bassett-Smith proposed a new genus to be 

 known as Helleria^ with the type species armata}^ This name had 

 already been used three times for crustacean genera which were not 

 copepods. This fact being called to his attention, Bassett-Smith in 

 November of the same year changed the name to Gyhicola}^ 



Gerstaecker published ^* a new genus of Siphonostoma called 

 Lonchidium^ with the single type species aculeatum. This proved 

 to be generically the same as Beneden's Kr^yeria, which had ap- 

 peared in the preceding year. This fact was recognized by Nord- 

 mann in 1864,^^ but it was misinterpreted by Bassett-Smith,^^ who 

 reversed the precedence and made Kr0yeria a synonym of 

 LoncMdvu/m. 



Risso in 1816 published a Histoire Naturelle des Crustaces des 

 Environs de Nice, in which he described (p. 162) a new species of the 

 genus CaZigus, G . imhricatus. Leach later in the same year estab- 

 lished in the Supplement to the Encyclopedia Brittanica (vol. 1, 

 p. 406) a new genus of Entomostraca, which he called Anthosoma 

 smAthii. Both Risso's specimens, which were examined by Leach, 

 and those of Leach himself were subsequently shown to be the same 

 as had been described by Abildgaard in 1794 as " Caligus crassusy ^^ 

 Leach's generic distinction, however, was valid, and hence the species 

 became Anthosoma crassum (Abildgaard) ; but in spite of this Risso 

 again described his species as new in Histoire Naturelle des prin- 

 cipals de I'Europe meriodionale (vol. 5, 1826, p. 136), this time under 

 the name Otrophesia hnhricata^ which, of course, becomes a synonym 

 of Anthosoma crassum. 



P. J. van Beneden established a new species and genus of parasitic 

 copepod,^^ which he named Pagodina rohusta. This is shown on 

 page 60 to be identical with the genus Nemesis and becomes a 

 synonym of the latter. 



For Nordmann 's proposed new genus, Stalagmus^ see page 36.
