TERTIAKY FORAMINIFERA OF VICTORIA. 11 



mouth of the Yarra " was intended ; and from Vine's description of the 

 material it probably came from Grice's Creek. In this interpretation I am 

 supported by Mr. T. S. Hall, M.A., to whom I am also indebted for a copy of 

 Vine's paper. 



Notwithstanding the work which has already been done by the authors just 

 mentioned, there are many other localities in Victoria which require to be 

 worked systematically for their Foraminifera before sufficient data are 

 collected to show adequately their distribution in the Tertiaries both vertically 

 and topographically. I therefore venture to offer a contribution to the study 

 of Victorian species, based on collections made by myself during the past four 

 years from other places in the State besides that of Muddy Creek. The list of 

 species here enumerated is by no means exhaustive, as additional forms are 

 found at each examination of fresh material. 



The foraminiferal rocks of Victoria represent, in their lithological structure, 

 deposits laid down under all the varied conditions between clear water 

 and turbid, both deep and shallow, which would result from intermittent or 

 continuous movements of a shore-line. Thus it will be apparent that by a 

 change of environment, along with a varying food-supply, the facies of the 

 foraminiferal fauna would vary. 



Sources of the present Collection. 



For the Balcombe's Bay deposit I am under great obligations to Mr. T. S. 

 Hall, who has supplied me with a large quantity of the washings from this, 

 as well as many other localities, especially along the coastal areas of Victoria. 



The Grice's Creek material was also furnished me by Mr. Hall, and I have 

 supplemented this by collecting samples from both the brown and the blue 

 clays of the same place. There is nothing distinctive in these two layers, 

 however, the brown colour being the result of an alteration of the iron 

 sulphide into the hydrous peroxide, as similarly recorded in the case of the 

 London Clay of Piccadilly *. 



The third locality herein dealt with is Kackeraboite Creek (of Selwyn) f, 

 or Dennant Creek (of Kitson) %. The clay exposed in this section, although 

 close to Grrice's Creek, seems to differ somewhat in its molluscan contents and 

 in the smallness and delicacy of most of the Foraminifera. Samples from 

 this bed were collected by myself. 



The fourth locality is situated near Altona Bay, where the blue clay was
