[Eead 10th November, 1898]. 



The occurrence of graptolites at Lancefield was first recorded 

 by myself some years ago when I described a species of Dictyo- 

 nenia from the locality.^ Mr. Gr. B. Pritchard then followed 

 with two papers on the graptolite fauna which will be subse- 

 quently referred to. The stratigraphical position was briefly 

 dealt with by myself in a paper on the geology of Castlemaine, 

 in which I showed that the Lancefield beds underlie the Bendigo 

 series, or, as I there called it, the Tetragraptus fruticosus zone.' 

 A further examination of the graptolites from the locality has 

 strongly confirmed the views I then held, as an examination of 

 the present paper will show. 



The beds are very rich in individuals in a good state of preser- 

 vation, and besides my own collection I have had the advantage 

 of examining those of Messrs. G. Sweet, F.G.S., and G. B. 

 Pritchard, and must acknowledge my thanks to them for placing 

 their large series so unreservedly at my disposal. 



The graptolites are preserved in an almost black, highly 

 pyritous shale intercalated with fine grained intensely hard 

 siliceous beds. 



The only other fossils I have seen in the beds are sponge 

 remains, a new species, Protospongia oblonga, being described in 

 the present volume, and what appears to be a Lingulocaris 

 allied to, if not identical witli L. maccoyi Eth. jr.
