TERTIARY FORAMINIFERA OF VICTORIA. 17 



specimens figured by Brady from comparatively shallow water in the Pacific 

 and elsewhere, in their generally greater breadth. 



Occurrence. — Grice's Creek, frequent; Balcombe's Bay, very rare; Kacke 

 raboite (^reek, frequent; Altona Bay Coal-Shaft, rare. 



Grenus MiLiOLiNA, Williamson. 



MiLiOLiNA OBLONGA, Montagu sp. (Plate 2. fig. 26.) 

 Vermicidmn ohlongum, Montagu, 1803, Test. Brit. p. 522, pi. 14. fig. 9. 

 MilioUna oblonffa, Mont, sp., Brady, 1884, Rep. Chall. vol. ix. p. 160, pi. 5. figs. 4a, 6; 

 Howchin, 1889, Trans. E. Soc. S. Australia, vol. xii. p. 2. 



The specimens in the present series are exceptionally small, but otherwise 

 typical. Howchin found this species in both the Upper and Lower Series at 

 Muddy Creek; Vine records it from the Port Phillip Tertiaries. 



Occurrence. — Balcombe's Bay, very rare; Altona Bay Coal-Shaft, frequent. 



MiLiOLiNA ciRCULARis, Bomemann sp. (Plate 2. fig. 27.) 



Trilocidina circtdaris, Bornemann, 1855, Zeitschr. d. deutsch, Gesellscli. vol. vii. p. 349, 

 pi. 19. fig. 4. 



MilioUna circularis, Born, sp., Brady, 1884, Rep. Chall. vol. ix. p. 169, pi. 5. figs. 13, 14 ; 

 Sherborn & Chapman, 1886, Journ. R. Micr. Soc. ser. II. vol. vi. p. 742, pi. 14. figs. 2 a, b; 

 Millett, 1898, Journ. R. Micr. Soc. p. 499, pi. 11. figs. 1-3. 



Our figured specimen is typical in outline, but the oral aperture is dentate. 

 Vine records this species from the Port Phillip Tertiaries. 

 Occurrence. — Balcombe's Bay, very rare. 



MiLiOLiNA SCHREIBERIANA, d' OrUgny sp. (Plate 2. fig. 2^.) 



TriloGulina schreiberiana, d'Orbigny, 1839, Foram. Cuba, p. 174, pi. 9. figs. 20-22. 



Triloculina austriaca, d'Orbigny, 1846, Foram. Foss. Vienne, p. 275, pi. 16. figs. 25-27. 



TrilocuUna schreiberiana, d'Orbigny, Schlumberger, 1893, Mem. Soc, Geol. France, vol, vi. 

 p, 204, pi. 1, figs. 42-44, woodcuts figs, 5, 6 ; Fornasini, 1900, Mem. R. Accad. Sci. lat. 

 Bologna, ser. V. vol. viii. p. 361, fig. 5, 



The triloculine forms of Bilocidina lucernula, Schwager *, are strongly 

 suggestive of aflSnity with this species ; their distinctness, however, is clearly 

 seen on making thin slices of the test. Our specimens agree with the normal 

 triloculine species referred to above, both as to internal arrangement and 

 external form. M. schreiberiana may be separated from B. lucernula, 

 however, without having recourse to the slicing of the shell, by the form of 

 the oral extremity, which is not prolonged as in the latter species. M. schrei- 

 beriana is again distinguished from M. trigonula, Lam. sp., by the accentuated 

 inflation of the chambers visible on the exterior. 



Occurrence. — Grice's Creek, common ; Kackeraboite Creek, frequent ; 

 Altona Bay Coal-Shaft, frequent.
