Family— MILIOLIM 



Sub -family — Milioliniisle

 of Elevated Deposits). 



Occurrence. — Sample No. 2, 113 fatboms, very rare. 



Biloculina elongata, d'Orbigny (for references see previous Reports on Foraminifera 

 of Elevated Deposits).

 one of large size ; No. 4, 153 fatboms, rare ; No. 5, 171 fatboms, very rare. 



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



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

 pi. ii, fig. 7. B. bradyi, Scblumberger, 1891, Mem. Soc. Zool. France, vol. iv, p. 557, 

 pi. x, figs. 63-71 ; woodcuts 15-19. B. bradyi, Scblumberger, Chapman, 1907, Journ. 

 Linn. Soc. Bond., Zool., vol. xxx, p. 13, pi. i, figs. 7, 8. Idem, 1909, Sub-Antarctic 

 Islands of New Zealand, vol. i, art. xv, p. 314, pi. xiii, fig. 1. 



Tbe distribution of tbis species is wide, and does not yet seem to be fully worked 

 out, on account of its baving been confused witb B. ringens, Lam. Tbe localities 

 include tbe Gulf of Gascony, and tbe sub-Antarctic islands of New Zealand (off tbe 

 Snares, N. of Auckland Island, and N. of Enderby Island). It bas also been recorded 

 as a Tertiary (Oligocene) fossil from Grice's Creek, Port Phillip. 



Tbe only example found in tbe present soundings is a fine specimen measuring 

 3-75 mm. in length. A variety of tbis species, viz. denticulata, Brady, bas been pre- 

 viously recorded from a raised beacb at 160 feet, on tbe slopes of Mount Erebus, between 

 Cape Royds and Cape Barne. 



Occurrence. — Sample No. 1, 110 fatboms, one specimen. 



Biloculina irregularis, d'Orbigny (for references see previous Reports on Foraminifera 

 of Elevated Deposits). 



Occurrence. — Sample No. 5, 171 fatboms, very rare ; No. 8, 353 fatboms, very rare.
