From the lower beds, which have been referred to as Eocene 

 on aQcount of the common fossils being the prevailing forms 

 found in such typical localities as Muddy Creek and Balcombe's 

 Bay, Mornington, usually regarded as of that age, the following 

 may be mentioned: — Dimya dissimilis, Tate; Lima bassii, 'T. 

 Woods ; L. linguli/'orniis, Tate ; Spondylus pseiidoradula, M'Coy ; 

 Barbalia celleporacea, Tate ; Chione cainozoica, T. Woods ; Chania 

 laniellifera, T. Woods ; Lyria harpularia, Tate ; Nassa tatei, 

 T. Woods ; Comes ligatus, Tate ; Trivia avellanoides, M'Coy ; 

 Seniicassii^ sitfflata, T. Woods ; Tenagodes occlusus, T. Woods ; 

 Turrilella murrayana, Tate ; Batliytoma rliomboidalis, T. Woods. 



The use of the terms Eocene and Miocene is not intended to 

 necessarily mean exact contemporaneity with deposits of that age 

 in Europe, but it has been found convenient to refer to our 

 deposits under those names, as judging from their moUuscan 

 contents there seems a sufficiently marked removal from present 

 time to permit of them being regarded as representing our early 

 Tertiary time. 



Tiiese remarks I make with the object of putting all collectors 

 on their guard, and of indicating that the various Tertiary outcrops 

 around Melbourne must have their relative age determined upon 

 their fossil contents, and in the absence of fossils no definite 

 opinion on the age can be expressed. 



Some short time ago a new drain was put in under the Essendon 

 railway line at the head of Athol-street, a short distance on the 

 Ascot Vale side of the Moonee Ponds railway station. The 

 bottom of the excavation for the drain went into decomposed 

 older basalt, and in the ferruginous sandy rock immediately over- 

 lying numerous casts and impressions of fossils could be obtained. 

 A collection of these specimens was made by Mr. D. W. Paterson, 

 a student at the Working Men's College, and he kindly allowed 

 me the opportunity of making a close examination, with the 

 result that the following identifications have been made : — Aturia 

 australis, M'Coy; Haiiolis ncevosoides, M'Coy; Liotia robliiii, 

 Johnston ; Dentalium mantelli, Zittel ; Calliostoma, sp.; Cyprcna, 

 sp. ; Patella, sp. ; Cerithiui)i Jleniitigtonensis, M'Coy; Latirus, 

 sp. ; Barbatia celleporacea, Tate ; Barbatia simulans, Tate ; 

 Cncullfca corioensis, M'Coy ; Spondylus pseudoradula, M'Coy ; 

 Diviya dissimilis, Tate ; Limatida jeffreysiana, Tate ; Chama
