ISOPOD GENUS LIGTA. 6^7 



well marked ; postero-lateral processes acute but short ; accessory 

 processes well marked. Mouth-parts : 2nd maxillse weakly lobed, 

 without hairy bristles on inner side ; maxillipede with palp deeply 

 lobed on margin into five portions, but segments otherwise in- 

 distinctly marked. First perceopod with prominent inner process 

 on propodus in male only. Expansions similar to those of 

 oceanica on carpus and merus of this leg. Uropods (separate) 

 7*5 mm. 



Distribution. Hawaiian Islands ; Molokai ; Matadona, China 

 Straits, British New Guinea. 



I have examined the specimens of the Willey Collection labelled 

 L. vitiensis, and identify them, without possible doubt, as this 

 species.

Male specimen described. 



Length 12 mm. Breadth 5*5 mm. 



Surfctce minutely granular. Eyes rather small and quadrangular, 

 and separated by twice their horizontal length. Ante^moi very 

 long and slender ; flagellum reaching as far back as hind border 

 of 4th abdominal somite ; peduncle to hind border of 3rd thoracic 

 somite. Flagellum with 20 small and setose segments. The 

 antennte are shorter in the female. The whole is as long as the 

 thorax, and the peduncle reaches half-way across the 3rd somite. 

 The segments of the flagellum are more setose than in the male. 

 Coxal plates very faintly marked or absent. In the female they 

 are marked by deep grooves on the 2nd, 3rd, and 4th thoracic 

 somites. ^?)cZome?z abruptly contracted. Telson urcuate ; postei-o- 

 lateral processes acute and produced, but shorter than middle of 

 hind border ; accessory processes marked by slight undulations. 

 Mouth-parts : 2nd maxilla with no trace of division into two 

 lobes; without hairy bristles on inner side. Maxillipede with. 1st 

 and 5th joints only, completely separated, remainder only 

 indicated by indentations on inner side. 1st and 2nd peroiopods 

 with carpus much swollen in male only ; subchelate. Uropods 

 5 mm. 



Distribution. Coast of New Zealand ; Steward Island ; Sunday 

 Island, Victoria ; Chile ; Juan Fernandez. 



I found that Budde-Lund's specimens, labelled Ligia cursor, 

 from Juan Fernandez (and described by him under that name 

 (1885)) agreed in every particular but length of antennae v/ith 

 Chilton's description (1901) of L. novce-zealandia. These
