502 DR G. S. BRADY ON 



Cythere prava, Baird. 



Cythere prava, Brady, "Ostracoda of Challenger Expedition," p. 92, pi. xxii. fig. 4 a-/. 



Habitat. — Suva, inside reef; Levuka, between tide-marks; Sava-Sava Bay, 4 fathoms; 

 Vuna Point, Taviuni, between tide-marks; Mango Island, fringing reef; Rambe - Island, 

 between tide-marks; Loma-Loma, in shore-sand ; Apia, Upolu, reef and shore-pools. 



This is the species noted in the " Challenger " Report as being found in dredgings 

 from the Admiralty Islands. It appears to be a common form among the South Sea 

 Islands, but differs a good deal from the European type. 



Cythere rectangularis, G. S. Brady. 



Cythere rectangularis, Brady, Les Fonds de la Mer, vol. i. p. 153, pi. xviii. figs. 13, 14 ; Linnean Soc. 

 Journal (Zoology), vol. xix. p. 310, pi. xl. figs. 7-9. 



Habitat. — Noumea, Porcheron's Beach ; Levuka, between tide-marks ; Vuna Point, 

 Taviuni, between tide-marks ; Rambe Island, between tide-marks ; Loma-Loma, in shore- 

 sand. 



The specific name rectangularis is given in the "Challenger" Report as a synonym 

 of Audei. This is a mistake, the shell figured as C. audei being quite distinct. The 

 South Sea specimens here noticed seem to be certainly identical with those found in 

 Ceylon, but they present a rather remarkable character, which is not visible in the Ceylon 

 specimens, — the presence on the ventral margin, near the posterior extremity, of two 

 very faint squamous dentations. This, however, though usual, is not visible on all 

 shells. 



Cythere Goujoni, G. S. Brady. 



" Cythere Goujoni, Brady, " Ostracoda of Challenger Expedition," p. 96, pi. xxv. fig. 7 a-g. 

 A widely distributed, and on that account, perhaps, a variable species. It has already 

 been recorded from Ceylon, Hong Kong, China, Port Jackson, and Booby Island. 

 Habitat. — Port of Noumea, 3-6 fathoms. 



Cythere infandibidata, n. sp. (PI. II. figs. 15, 16). 



Shell, seen from the side, oblong, subquadrangular, nearly equal in height throughout, 

 height equal to half the length. Anterior extremity well rounded, divided into numerous 

 short, blunt teeth; posterior produced and angulated a little below the middle, thence 

 sloping with a very slight inward curve upwards and downwards ; ventral margin almost 

 straight, slightly encroached upon in the middle by the central protuberance of the shell, 

 rounded off in front, angulated behind ; dorsal margin parallel with the ventral, sinuous, 

 joining the posterior margin at an obtuse angle ; elevated over the anterior hinge. Seen 

 from above, the shell has somewhat the shape of a funnel with a large triangular prominence 

 in the middle of the wide end ; greatest width near the hinder extremity, and equal to 

 about two-thirds of the length ; from this point the lateral margins approximate with a 

 convex curve until near the front, which is formed by a wide obtusely- rounded, sub- 

 truncate process ; backvvardly the sides converge almost at a right angle towards the
