A NARROW LODGING 355 



this species agrees in its habits with those of the so-called 

 Glossobius Gyinothoa aistrum (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 

 Cymothoas.' 



TchthyoxSrvus, Herklots, 1870, means ' an enemy of 

 fish.' This is more plain speaking than hair eiWe' b Ichthyo- 

 -pMlus, but the treatment to which these genera expose 

 the fish is the same, whether spoken of as love or hate, 

 Ichthynxenus 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 I3onnier sug- 

 gest that two larvae 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, lohthyozenus montanus, Schiodte 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 Owenii, Milne- 

 Edwards, and monacanthi and cavdatus, established by 

 Schiodte 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 pereeon 

 is for the most jDart very broad. By the widening of some 

 of the joints the hinder legs, especially the last pair, 

 assume a very curious appearance. 



Harponyx pranizoides, 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 

 CymothoidEe, without explanation of the limits assigned to 

 that faniily. The long second antennas suggeist that the 

 animals are not fully adult, though they are too well deve-
