410 A HISTORY OF RECENT CRUSTACEA 
Athelque intermedia, Hesse, 1877, on Eupagurus cua- 
nensis (‘Thompson). 
Athelque Cardone, Kossmann, on Clibanarius misan- 
thropus, Risso. 
Athelque lorifera, Hesse, 1877, on Hupagurus cuanensis 
(Thompson), tugether with several specimens of Pelto- 
gaster. 
Athelque cladophora, Hesse, 1861. 
Pleurocrypta, Hesse, 1865 The male has the pleon as 
in Phiyxus. In the female, it is stated, ‘the five segments 
of the pleon are provided each, on each side, near the 
margin, with a branchia of oval form, filiform, thin, flat, 
very contractile.’ The sixth segment has two small ap- 
pendages. 
Pleurocrypta galatece, Hesse, 1865, on Galathea squami- 
fera, Leach. According to Giard and Bonnier the Phryzxus 
longibranchiatus of Bate and Westwood is the Phryxus 
stage of this Plewrocrypta. 
Pleurocrypta porcellance, Hesse, 1877, on Porcellana 
longicornis (Linn.). 
Pleurocrypta strigosa, Giard and Bonnier, 1890, on 
Galathea strigosa, Fabricius. 
_ Pleurocrypta Hendersonii, Giard and Bonnier, 1890, on 
Galathea dispersa, Bate, from the Clyde. 
Paleegyge, Giard and Bonnier, 1888. The male has 
the pleon composed of well-separated segments, each on the 
ventral side carrying rudiments of pleopods. The authors 
in 1890 suggest that it will probably be necessary to 
make two sections of the genus, one characterised by the 
plates of the pleon in the female being furnished with 
warts or tubercles, and including the species parasitic on 
Anomala and Thalassinida, the other characterised by the 
appendages of the pleon being entirely smooth, and in- 
cluding the species parasitic on the Hukyphota (see page 
224). For the former division the genus Pseudione, Koss- 
mann, seems to be the appropriate name, and for the latter 
Palegyge. As the name implies, this genus is regarded 
by its authors as representing an ancestral form of Gyge.
