It affects fairly deep-water areas. Recorded by G. R. Vine, Junr., from the 

 Port Phillip Tertiaries. 



Occurrence. — Grice's Creek, frequent ; Altona Bay Coal-Shaft, frequent. 



BoLiviNA PUNCTATA, d' OrUgny. (Plate 4. fig. 80.) 



BoKvina punctata, d'Orbigny, 1839, Foram. Am^r. Merid. p. 61, pi. 8. figs. 10-12; 

 Howchin, 1889, Trans. E. Soc. S. Australia, vol. xii. p. 8. 



This well-known Tertiary species is widely distributed, and it occurs in 

 soundings from almost every sea. 



It has been recorded from the Lower Bed of Muddy Creek (Howchin). 

 Occurrence. — Grice's Creek, common ; Altona Bay Goal-Shaft, frequent. 



BoLiviNA NOBiLis, Hantkeii. (Plate 4. fig. 81.) 



Bolivina nohilis, Hantken, 1875, Mitth. Jahrb. d. k.-ung. Geol. Anstalt, vol. iv. p. 65, 

 pi. 15. figs. 4 a, 5; Chapman, 1892, Quart. Journ. Geol. Soc. vol. xlviii. p. 516, pi. 15. 

 fig. 11 ; Millett, 1900, Journ. R. Micr. Soc. p. 541, pi. 4. fig. 4. 



This elegant species was first found as a fossil in the Clavulina Szaboi beds 

 of Ofen, Hungary ; and the writer found it in the Upper Chalk of Taplow, 

 England. The ' Challenger ' dredgings brought it to light as a recent species, 

 apparently restricted to the South Pacific. It has since been found off the 

 "West Coast of Africa (Egger), and Millett records it as abundant in the 

 Malay Archipelago. 



Occurrence. — Grice's Creek, common ; Balcombe's Bay, rare ; Kackera- 

 boite Creek, very rare. 



Bolivina robusta, Brady. (Plate 4. fig. 82.) 



Bolivina robusta, Brady, 1881, Quart. Journ. Micr. Sci. vol. xxi. n. s. p. 57 ; id., 1881, 

 Rep. Ohall. vol. ix. p. 421, pi. 53. figs. 7-9 ; Millett, 1900, Journ. E. Micr. Soc. p. 543, 



As a recent species this form is well distributed. It is occasional in 

 certain Tertiary beds, and is abundant in the L. Pliocene clay of St. Erth, 

 Cornwall, England. Vine records the species from the Port Phillip 

 Tertiaries. 



Occurrence. — Altona Bay Coal-Shaft, rare. 



Bolivina limbata, Brady. (Plate 4. fig. 83.) 



Bolivina limbata, Brady, 1881, Quart. Journ. Micr. Sci. vol. xxi. u. s. p. 57 ; id., 1884, 

 Rep. Cliall. vol. ix. p. 419, pi. 52. figs. 26-28 ; Howchin, 1889, Trans. R. Soc. S. Australia, 

 vol. xii. p. 8 ; Egger, 1893, Abhaudl. k.-bayer. Akad. Wiss., math.-nat. 01. 11, vol. xviii. 

 p. 300, pi. 8. figs. 10-12. 



Our fio-ured specimen is a very minute form. It is referable to the above 

 species, which is commonly found in the neighbourhood of coral reefs at the 

 present day. The bifarine form, with later uniserial chambers, is more often 

 met with in recent dredgings. Howchin records this species from the Lower 

 Bed of Muddy Creek. 



Occurrence. — Balcombe's Bay, very rare.
