TERTIARY FORAMINIFERA OF VICTORIA. 13 



Description of the Species. 



Order FORAMINIFEEA. 



Family MILIOLIDiE. 



Subfamily Milio lining. 

 Genus BiLOCULiNA, d'OrUgny. 



BiLOCULiNA BULLOIDES, cVOrUgny. (Plate 1. figs. 3, 4.) 



Biloculina bulloides, d'Orbigny, 1826, Ann. Sci. Nat. vol. vii. p. 297, No. 1, pi. 16. figs. 1-4; 

 Schlumberger, 1887, Bull. Soc. Geol. France, ser. III. vol. xv. p. 120, pi. 15. figs. 10-13, 

 woodcuts figs. 1-5 ; Howchin, 1889, Trans. R. Soc. S. Australia, vol. xii. p. 1. 



Fairly typical specimens showing the slender T-shaped epistoma are not 

 rare. The shells are generally undersized, and have a tendency to become 

 pyriform in a slight degree, thus linking the species with B. ringens. 

 Howchin recorded this species from Muddy Creek, but only from the Upper 

 Bed (Kalimnan). 



Occurrence. — Grice^s Creek, common ; Balcombe^s Bay, very rare. 



Biloculina ringens, Lamarck sp. (Plate 1. figs. 9, 10.) 



MilioUtes ringens, Lamarck, 1804, Ann. du Museum, vol. v. p. 351 ; vol. ix. pi. 17. fig. 1. 



Biloculina ringens, Lam. sp., Schlumberger, 1887, Bull. Soc. G^ol. J'rance, ser. III. vol. xv. 



p. 126, pi. 15. figs. 14-18, woodcuts figs. 6-9 ; Howchin, 1889, Trans. R. Soc. S. Australia, 



vol. xii. p. 1. 



The specimens in the present collection are medium-sized. They have a 

 sub-elliptical test, seen from the front, and the face of the penultimate chamber 

 is somewhat pyriform. The epistoma is bifid with the tips more or less 

 recurved. A moderately large specimen (not figured) closely resembles the 

 form common in the English " Coralline " (polyzoan) Crag*. Howchin has 

 noted this species both from the Upper and Lower Beds of Muddy Creek, and 

 Vine from the Port Phillip Tertiaries. 



Occurrence. — In the present series B. ringens is somewhat frequent ; from 

 Grice's Creek, Balcombe's Bay, Kackeraboite Creek, and Altona Bay Coal- 

 Shaft. 



Biloculina Bradii, Schlumberger. (Plate 1. figs. 7, 8.) 



Biloculina ringens, Brady (non Lamarck), 1884, Rep. Chall. vol. ix. p. 142, pi. 2. fig. 7. 

 B. Bradtji, Schlumberger, 1891, Mem. Soc. Zool. France, vol. iv. p. 557, pi. 10. figs. 63-71, 

 woodcuts figs. 15-19. 



The above species has been clearly diagnosed by Schlumberger, who has 

 * Jones, Parker, and Brady, Mon. Foram. Crag, 1866, pi. 3. figs. 26, 27.
