Foraminifera.] SUBANTARCTIC ISLANDS OP NEW ZEALAND. 315 



Distrihidion. — Should Dr. Brady's records of B. ringens prove to be referable to 

 the above form, the living representatives are cosmopolitan. Schlumberger records 

 B. hradii from the Atlantic (Gulf of Gascony ; 1,850 metres). The writer has also 

 recorded this form from the Tertiary (Balcombian) clays of Port Phillip. 



Present Occurrence. — Off the Snares ; 60 fathoms ; very common. Twenty 

 miles north of Auckland Island ; 85 fathoms ; frequent. Ten miles north of Enderby 

 Island ; 85 fathoms ; frequent. 



Biloculina bradii, Schlumberger, var. denticulata, Brady. (Plate XIII, fig. 2.) 



Biloculina ringens, Lam., var. denticvlata, Brady, 1884, Rep. Chall., vol. ix, 

 p. 143, pi. iii, figs. 4, 5. 



Our figured specimen shows strong denticulations along the lateral edges, but 

 not 80 well marked at the aboral end as in Brady's example. 



Distribution. — Dr. Brady regarded this variety as belonging essentially to the 

 coral-reef fauna. It occurred in the " Challenger " dredgings at several stations in 

 the Pacific. 



Present Occurrence. — Twenty miles north of Auckland Island ; 85 fathoms ; 

 very rare. 



Biloculina vespertilio, Schlumberger. (Plate XIII, figs. 4 a, 6.)

 vol. iv, p. 561, pi. X, figs. 74-76 ; woodcuts, 20-22. 



Distribution. — Gulf of Gascony ; 1,850 metres (Schlumberger). 

 Present Occurrence. — Off the Snares ; 60 fathoms ; very rare. Ten miles north 

 of Enderby Island ; 85 fathoms ; very rare.

 man, 1905, Trans. N.Z. Inst., vol. xxxviii, p. 80. 



Distribution. — The original specimens were dredged in the Mediterranean. The 

 writer has pJready noted this species from Great Barrier Island, New Zealand, at 

 110 fathoms, and it was moderately abundant. 



Present Occurrence. — Ten miles north of Enderby Island ; 85 fathoms ; rare. 



Biloculina lucernula, Schwager. 



Biloculina lucerntda, Schwager, 1866, " Novara " Exped., geol. Thiel,

 pi. xii, figs. 90-96 ; woodcuts, 37-41.
