THE BOPYRIDAE 411 
Paleegqyge Borrei, Giard and Bonnier, 1888, on the 
freshwater species Paleemon dispar, von Martens. 
Palcegyge Bonnieri, Max Weber, 1892, on Palceemon lar, 
Fabricius. 
Palegyge fluviatilis, Max Weber, 1892, on Palemon 
lampropus, de Man. 
Palegyge de Mani, Max Weber, 1892, on Palemon 
pilimanus, de Man. 
Palegyge afjinis (Sars, 1882), on Pandalus leptorhyn- 
chus, Kinahan. 
Paleegyge Hoyli, Giard and Bonnier, 1890, on Pandalus 
annulicornis (i.e. Montagui), Leach. 
Pseudione, Kossmann, 1881, has the ‘ maxillipeds of the 
male quite rudimentary.’ 
Pseudione callianasse, Kossmann, 1881, on Callianassa 
subterranea (Montagu). Since Giard and Bonnier refer 
this species to their Paleeqyge, 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 
Eupagurus bernhardus (Linn.). This is described in the 
‘History of British Sessile-eyed Crustacea’ as Phryxus 
Hyndmannt. Moreover, the Phryzus fusticaudatus of Bate 
and Westwood is, according to the often quoted authori- 
ties, the phryxoid stage of the same species. By phryxoid 
stage is meant the form of the female immediately follow- 
ing the cryptoniscian stage. 
Pseudione Fraissei (Kossmann, 1886), on Clibanarius 
misanthropus, Risso. 
Pseudione Dohrni (Giard and Bonnier, 1890), on Cal- 
liunassa truncata, Giard and Bonnier. This parasite was in 
one instance found on each side of the host. 
Pseudione insignis (Giard and Bonnier, 1890), on 
Munida rugosa (Fabricius). 
Pseudione confusa (Norman, 1869), on Galathea dispersa, 
Bate. This was erroneously assigned at first to Galathea 
intermedia, Lilljeborg, and described by Bate and West- 
wood as. Phryzus galathee, and supposed by them to be
