314 SUBANTARCTIC ISLANDS OF NEW ZEALAND. [Foraminijera. 



DistribuHon. — This species has a wide geographical range. The " Challenger " 

 obtained it from the New Zealand area. 



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

 north of Auckland Island ; 85 fathoms ; very common. Ten miles north of Enderby 

 Island ; 85 fathoms ; very common.

Our specimens are not so uniformly serrated as Brady's figured example, but 

 they are undoubtedly referable to that form. They more nearly resemble the figures 

 given by Dr. Goes. 



Distribution. — This species, curiously, in common with other types here enu- 

 merated, occurs at antipodean areas. Brady's examples came from the North 

 Atlantic and South Pacific, and it is recorded from the New Zealand area in the 

 " Challenger's " " Summary of Results." Schlumberger obtained it from the Gulf 

 of Gascony. 



Present Occurrence. — Off the Snares ; 60 fathoms ; rare.

p. 139. B. sarsi, Schlumberger, 1891, Mem. Soc. Zool. France, vol. iv, 



p. 553, pi. ix, figs. 55-59 ; woodcuts, 10-12. B. sarsi, Schlumb., 



Chapman, 1907, Journ. Linn. Soc. Lond., Zool., vol. xxx, p. 14, pi. i, 



figs. 1, 2. 



Distribution. — The original specimens were dredged by M. Sars in the North Sea. 



This species has already been described from the Tertiary (Balcombian) clays 



of Port Phillip, where they attained especially large dimensions. 



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

 north of Auckland Island ; 85 fathoms ; frequent ; small examples. Ten miles 

 north of Enderby Island ; 85 fathoms ; rare. 



Biloculina bradii, Schlumberger. (Plate XIII, fig. 1.) 



Biloculina ringens, Brady (non Lamarck), 1884, Rep. Chall., vol. ix, p. 142, 



pi. ii, fig. 7. B. bradyi, Schbimberger, 1891, Mem. Soc. Zool. France, 



vol. iv, p. 557, pi. x, figs. 63-71 ; woodcuts, 15-19. B. bradii, Schlumb., 



Chapman, 1907, Journ. Linn. Soc. Lond., Zool., vol. xxx, p. 13, pi. i, 



figs. 7, 8. 



A good series of this form was found, and the examples are fairly typical. 



Schlumberger distinguishes the Eocene B. ringens from the living species by the 



aperture and relative thickness of the walls.
