20' MR. FREDERICK CHAPMAN ON THE 



all foraminiferal deposits o£ Tertiary age. As a recent form it occurs 

 as far north as Baffin's Bay, and has been also recorded from several places 

 off the coast of Australia. 



Howchin records this species from the Lower Bed of Muddy Creek. 



Occurrence. — Grrice's Creek, frequent. 



MiLiOLiNA AGGLUTINANS, d' OrUgny sp. (Plate 2. fig. 36.) 



Quinqueloculina aggMinans, d'Orbigny, 1839, Foram. Cuba, p. 168, pi. 12. iigs. 11-lS. 



MilioUna agglutinans, d'Orb. sp., Brady, 1884, Eep. Chall. vol. ix. p. 180, pi. 8. figs. 6,7; 

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



This is a variable species in the present series, some of the specimens being- 

 more elongate than others ; this peculiarity was also remarked upon by 

 Howchin, who recorded it from Muddy Creek, where in the Lower Bed it 

 is very common, and in the Upper Bed rare. Vine also notes this species 

 from the Port Phillip Tertiaries. 



Occurrence. — Grrice's Creek, common ; Balcombe's Bay, common ; Kac- 

 keraboite Creek, frequent ; Altona Bay Coal-Shaft, frequent. 



MiLiOLiNA LINN^ANA, d'' OrUgny sp. (Plate 2. fig. 37.) 



Triloculina linncsana, d'Orbigny, 1839, Foram. Cuba, p. 153, pi. 9. figs. 11-13. 



MilioUna linnceana, d'Orb. sp., Brady, 1884, Rep. Chall. vol. ix. p. 174, pi. 6. figs. 15-20 ; 

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



The present examples are typical in having an elliptical test, sculptured 

 with coarse and fairly deep longitudinal furrows. 



The fossils hitherto recorded are from the Tertiaries of the Vienna Basin 

 and the Island of Ischia, and it was also found by Howchin in both Lower 

 and Upper Beds at Muddy Creek. M. Unnceana is found in the recent 

 condition in fairly shallow-water areas, chiefly within the tropical zone. 



Occurrence.— (Jrice's Creek, frequent. 



MiLiOLiNA VENUSTA, Karver sp. (Plate 2. fig. 38.) 



Quinqueloculina venusta, Karrer, 1868, Sitzungsb. d. K. Ak. Wiss. Wien, vol. Iviii. Abth.

MilioUna venusta, Karrer sp., Brady, 1884, Rep. Chall. vol. ix. p. 162, pi. 5. figs. 6, 7. 



This species dates from the Cretaceous (Gault of England). Karrer's 

 specimens came from the Miocene of Kostej, Banat. As a living form it is 

 essentially of deep-water habit. 



Occurrence.— Grices Creek, rare.
