TERTIARY FOKAMINIFERA OF VICTORIA. 29 



Its earliest occurrence seems to have been in the Upper Chalk of Riigen. It 

 has been found as a recent form in both the Atlantic and Pacific Oceans, and 

 appears to prefer deep water. 



Occurrence. — Grice's Creek, very common.

It is interesting to meet with the above species in the Tertiary of Grice's 

 Creek, since it is more characteristic of the Cretaceous in other parts of the 

 world. It has, however, been found in the Older Tertiary (Szaboi-schichten) 

 of Hungary. 



Vine also recorded this form (' Gaudryina Reussi ') from the Port Phillip 

 Tertiaries. 



Occurrence. — Grice's Greek, very rare. 



Genus Clavulina, (TOrUgny. 

 Clavulina communis, (VOrhigny. (Plate 3. fig. ^&.)

The geological range of this species extends through the whole of the 

 Tertiary deposits, and it also occurs in the recent condition. Our specimens 

 are quite typical in every respect, and comparable with those found in the 

 Northern hemisphere. 



Howchin found this species in both the Lower and Upper Beds of Muddy 

 Creek, and Vine recorded it from the Port Phillip Tertiaries. 



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

 Kackeraboite Creek, very common. 



Clavulina angularis, d'Orbigny. (Plate 4. figs. 68-73.)

There are two distinct forms of the tricarinate ClavuUnce in the present 

 series, one of which is parallel-sided and only bluntly keeled, the other beino- 

 elongately pyramidal in shape and with sharp sahent edges. Upon slicino- 

 the tests, the former of these is seen to have a comparatively large initial 

 chamber with only a single group of three chambers in the triserial portion 

 of the test, and this to be followed by an irregularly shaped quasi-textularian 

 series, leading to the uniserial portion, which in the figured specimen shows 

 five superposed chambers.
