of extraneous origin the general results are identical. The time 

 horizon may be indicated by Older Pleistocene.-' 



(2) The faunula belongs to shallow water, not absolutely 

 littoral, but the depth indicated by the species was not beyond 

 the influence of wave disturbance in rough weather. 



(3) The mineralization of the fossils must not be regarded as 

 evidence of greater antiquity than the corresponding deposit at 

 Limestone Creek, wherein the tests are unaltered." 



Professor Tate's determinations are the following : — 

 Purpura textiliosa, Lam. 

 Siphonalia tasmaniensis, Adams and Angas 

 Nassa lyrella, Beck 

 Nassa fasciata, Lam. 

 Batillaria cerithium, Quoy 

 Turritella clathrata, Kiener 

 Natica plumbea, Lam. 

 Risella plana, Quoy 

 Ostrea angasi, Sow. 

 Osti'ea mordax, Gould 

 Pecten antiaustralis, Tate 

 Mytilus magellanicus, Lam. (?) 

 Mytilus planulatus, Lam. 

 Meretrix alatus, Reeve 

 Corbula scaphoides, Hinds 

 Barnea australasiae, Sow.

Magellania flavescens. Lam. 

 Balanus, sp. 



A very important conclusion follows from the fossil evidence 

 here produced, namely, that the age of the superincumbent 

 basalt is brought still nearer to our own times; it cannot be 

 older than Newer Pliocene, and may even be Pleistocene. 



1 The Limestone Creek beds are by ilr. Dennant assigned to the Newer Pliocene, the 

 extraneous origin of some shells in the deposit being, he says, a surmise only, and not 

 demonstrable from an examination of the sections. Following him, I call the Moorabool 

 bed Newer Pliocene.
