Bopyrid was first described by the present author as
ffin is. It was subsequently referred by M.M. Giard and Bon-
, the type of which is P. Barrel, found on a fresh-
water prawn (Palsemon dispar) from the 'Indian Archipelago. On comparing the
figures and description given by the above named authors, I find, however, that this
form differs in several points very essentially from the one here treated of, exhibiting,
it would seem, a closer relation to the genus Bopyrus. On the other hand, I
cannot see any objection to including the present species in the genus Pxeu-
(lioiic of Kossman; for the distinctive character quoted by
M.M. Giard and
Bonnier between the genera Paloegyge and Pseudlone, viz., the presence or absence
of tubercles on the pleopoda, is certainly of no generic value, since there are spe-
cies in the genus Pkurocrnpta both with and without such tubercles.
Occurrence. The type specimen, described by the present author in
1882, was found in the branchial cavity of a Pandalm leptorhynchus
taken off
the west coast of Norway. Subsequently I have had the opportunity of ex-
amining 3 other specimens preserved in our Univ. Museum and named Bopyrus
n-iiiH/orinii K;ibr. According to the label, they were taken by my
late father at
Drobak from the branchial cavity of Partdalus Montagui (annulicornis), and in
all respects agreed exactly with the specimen formerly examined by me. I can-
not therefore doubt that the nominal species Palaxjyge Hot/Hi Giard & Bonnier,
which was likewise procured from Pandalus Montagui, is the very same species.
Distribution. British Isles. (Giard & Bonnier).
