Introductory Note. 



In this and the two succeeding parts are eniljodied the palaeonto- 

 logical results of a somewhat exhaustive study of the material 

 brought up by borings in the Mallee near Ouyen, numbered 1-11. 

 The actual boring was carried out between August, 1908, and 

 August, 1909. The borings are all in the County of Weeah, and 

 •commence at about six miles east of the South Australian boundary, 

 and fifty miles north of the 36th paiallel at Pinaroo. The bores 

 are situated at distances of two to four miles apart. 



The second part of this report will comprise the niollusca, 

 written in conjunction with Mr. C. J. Gabriel, and the thiid part, 

 by myself, will comprise the groups of the Ostracoda and Fishes. 



The report containing the general results will subsequently 

 appear in the publications of the Geological Survey of Victoria. 



Plantae. 



Boring fungi, indet. 



In one in.stance. Bore 9. 'Mh-'.Vlb feet, the remains of a boring 

 fungus are seen in the outer, aragonitic layer of a (?) J)osiiiea 

 valve. The thallus forms stellate groups, measuring about 3 mm. 

 across. The tubes average about .115 mm. in diameter. A micro- 

 scope section did not leveal any recognisable structure. 



In Bore 1. 154-190 feet, the rolled sliells of niollusca are freely 

 riddled with a similai- form of perfoiating plant. Init showing less 

 regularity in outline.
