this species agrees in its habits with those of the so-called 
Glossobius Cymothoa cstrum (Linn.) is also often taken 
on the tongues of fishes. It is said to have been once 
found within the shell of Strombus gigas. It is reckoned 
‘among the largest and noblest of the family of the 
Cymothove.’ 
Ichthyoxénus, Herklots, 1870, means ‘an enemy of 
fish.’ This is more plain speaking than Latreille’s Ichthyo- 
philus, but the treatment to which these genera expose 
the fish is the same, whether spoken of as love or hate, 
Ichthyouenus Jellinghausii, Herklots, excavates in the under 
side of Pontius (Barbodes) maculatus, Bleeker, behind the 
ventral fins, a deep hole wherein the male and female live 
together. ‘The fish is found in the river Tjikerang, in the 
kingdom of Bandong in Java. The two parasites, lodged 
in the invagination of the outer wall of the fish’s abdomen, 
become too large when adult to be able to pass through 
the orifice of their cell. MM. Giard and Bonnier sug- 
gest that two larve enter together, and that one of them 
having the more favourable position continues its evolution 
beyond the male stage and becomes the female partner. 
A second species, Ichthyoxenus montanus, Schiddte and 
Meinert, comes from a fish taken in the streams of the 
Himalayan mountains. 
Ourozeuktes, Milne-Edwards, 1840, contains three 
species, all from Australia, the original Owen, Milne- 
Edwards, and monacanthi and caudatus, established by 
Schiddte and Meinert. In this genus the segments of the 
pleon, though distinguishable, are fused together, and that 
part of the animal is greatly narrowed, whereas the perzeon 
is for the most part very broad. By the widening of some 
of the joints the hinder legs, especially the last pair, 
assume a very curious appearance. 
Harponyx pramzoides, Sars, 1882, a new genus and 
species founded on two specimens each a quarter of an 
inch long, is referred rather vaguely to the family of the 
Cymothoidz, without explanation of the limits assigned to 
that family. The long second antenne suggest that the 
animals are not fully adult, though they are too well deve-
