The Bopyrid described in the present paper was detected 
by my friend Mr. Buitendyk, when examining a lot of the 
large Palaemon carcinus, offered for sale on the passar 
(market) of Tandjong-Priok. He collected no less than 
thirteen specimens of this parasite, but regret that the exact 
number of Palaemonidae examined by him is unknown to 
me. Thanks the careful investigations of Giard '), Bonnier °) 
and Max Weber ®), it is well known that the Palaemonidae 
of the Malayan Archipelago are especially infested by 
members of the genus Palaegyge, containing Bopyridae 
characterized by having rudimentary uropods in the female 
and the segments of the pleon distinctly separated from 
each other in the male“). As far as I know, only seven 
species are hitherto described, found on six species of Pa- 
laemonidae, viz. Palaegyge Borrei and — Webert (on
