OSTRACODA COLLECTED IN THE SOUTH SEA ISLANDS. 505 



the male (?) is not so high as that of the female, and the posterior extremity is almost 

 rectangularly truncate. Length (of both sexes) 1 mm. 



Habitat. — Suva Bay, 12 fathoms. My cabinet contains a good series of this fine 

 species, from a dredging in Princess Charlotte Harbour, West Australia. An examina- 

 tion of this series shows that the specimen figured in the Transactions of the Zoological 

 Society (loc. cit.) is a young shell of the same species. I have, therefore, given here 

 figures of the adult female form from the West Australian series. 



Genus Limnicy 'there, G. S. Brady. 



Limnicythere Fijiensis, n. sp. (PI. II. figs. 33, 34). 



Shell, seen from the side, reniform, slightly higher in front than behind, height equal 

 to rather more than half the length. Anterior extremity wide and boldly rounded, 

 posterior narrower, somewhat oblique (the obliquity looking downwards), and not very 

 fully rounded ; both extremities more or less crenated, the crenations sometimes extending 

 even on to the dorsum ; dorsal margin very slightly arched, ventral deeply incurved in 

 the middle. Seen from above, the outline is irregularly wedge-shaped, more than twice as 

 long as broad, the greatest width near the hinder end, anterior extremity blunt and 

 emarginate in the middle, the sides gradually diverging to near the posterior extremity, 

 then converging rather suddenly and in an irregular line to the wide and blunt extremity. 

 Surface of the shell thickly covered with small oblong, impressed markings, and bearing a 

 more or less distinct central tubercle with a surrounding depression ; within the ventral 

 border is a not very distinct curved ridge, and in some specimens there are irregular 

 faint undulated ridges on the central portion of the valve. Length 5 mm. 



Habitat. — Levuka, between tide-marks ; Rambe Island and Vuna Point, Taviuni, 

 between tide-marks ; Mango Island, pools on the fringing reef ; Loma-Loma, in shore- 

 sand. 



I have had no opportunity of examining the soft parts of this species, all the 

 specimens being merely empty shells ; but from the general characters of the shell, I 

 entertain little doubt that it belongs to the genus Limnicythere. 



Genus Cytheridea, Bosquet. 

 Cytheridea spinulosa, G. S. Brady. 



Cytheridea spinulosa, Brady, " Ostracoda of Challenger Expedition," p. 112, pi. xxxiii. fig. 6 a-d. 



This species, originally described from specimens taken at Mauritius, seems to be 

 widely distributed in the Southern Hemisphere. Amongst the " Challenger " dredgings, 

 it was found at Amboyna and in a deep dredging from the South Pacific. Amongst the 

 gatherings here described, it occurs as follows : — At Noumea, in shore-sand, from 

 Porcheron's Beach and Artillery Point, and in dredgings from 2 to 6 fathoms ; mud-flats 

 at Suva ; at Sava-Sava Bay, Vanua Levu, 4 fathoms ; and at Eambe Island, between 

 tide-marks.
