THE BOPYRIDJE 411 



Talcegyge Borrei, Giard and Bonnier, 1888, on the 

 freshwater species Palcemon dispar, von Martens. 



Palcegyge Bonnieri, Max Weber, 1892, on Palcemon lar, 

 Fabricius. 



Palcegyge fluviatilis, Max Weber, 1892, on Palcemon 

 lami^roims^ de Man. 



Palcegyge de Mani, Max Weber, 1892, on Palcemon 

 pilimanus, de Ma.n. 



Palcegyge affinis (Sars, 1882), on Pandalus leptorliyn- 

 cJiKS, Kinahan. 



Palcegyge Hoyli, Giard and Bonnier, 1890, on Pandalus 

 annulicornis (i.e. Alontagui), Leach. 



Pseiiclio7ie, Kossmann, 1881, has the ' maxillipeds of the 

 male quite rudimentary.' 



Pseudione callianassce, Kossmann, 1881, on CalUcmassa 

 suhterrcmea (Montagu). Since Giard and Bonnier refer 

 this species to their Palcegyge, and also, as just observed, 

 look forward to a subdivision of that genus, questions of 

 priority will be best arranged by retaining Pseudione for 

 one of the sections. 



Pseudione Hyndmanni (Bate and Westwood, 1867), on 

 Eiqjagurus hernhardtis (Linn.). This is described in the 

 ' History of British Sessile-eyed Crustacea ' as Phryxus 

 HyndnictMni. Moreover, the Phryxus fusticaudatus of Bate 

 and Westwood is, according to the often quoted authori- 

 ties, the phryxoid stage of the same species. Byphryxoid 

 stage is meant the form of the female immediately follow- 

 ing the cryptoniscian stage. 



Pseudione Fraissei (Kossmann, 1886), on Clihanarius 

 inisanthropus, Risso. 



Pseudione Bolirni (Giard and Bonnier, 1890), on Ccd- 

 lianassa tt'incata^ Giard and Bonnier. This parasite was in 

 one instance found on each side of the host. 



Pseudione insignis (Giard and Bonnier, 1890), on 

 Municla rugosa (Fabricius). 



Pseudione confusa (Norman, 1869), on Gcdathect dispersa, 

 Bate. This was erroneously assigned at first to Galafhea 

 intermedia, Lilljeborg, and described by Bate and West- 

 wood as Phryxus galathece, and supposed by them to be
