[Plate III.] 



The Silurian fauna of certain portions of the Paleozoic dis= 

 tricts of South-eastern Australia, especially that of the colony 

 of Victoria, is of peculiar interest, on account of the close re- 

 lationship existing between it and that of a corresponding age 

 in Great Britain. This was originally pointed out by Prof. 

 IVPCoy in a small pamphlet published for the Intercolonial 

 Exhibition of 1861*, where he states that he had recognized 

 numerous species of Graptolites in the rocks of the colony 

 characteristic of beds of Lower Silurian age elsewhere. 

 Amongst these were Diphgraptus pristis, His., identical with 

 specimens from the south of Scotland, D. mucronatus, Hall, 

 and D. ramosus, Hall, similar to those of the Utica slate of 

 New York, together with many double or twin Graptolites
