Neiv or Little-known VicUman Fossils. 79 



McCoy referred to Deep Creek as the locality for Siphonotreta 

 (Ann. Mag. Nat. Hist., ser. 3, vol. xx., 1867, p. 201) he evidently 

 had in mind the name Deep Creek by which the Saltwater River 

 is sometimes known higher up, near Lancefield, and this possible 

 explanation is further strengthened by McCoy's record of 

 Siphonotreta on the Survey map 7 S.E. at localities Ba 61 to 63, 

 Saltwater River, while Deep Creek has no such record. There 

 is therefore no evident reason for the colouring of the area round 

 Deep Creek as Lower Silurian (Ordovician). 



Within the last few weeks I have found in the Museum the 

 Survey specimens collected at the locality marked on the Geo- 

 logical maps Ba 60, Deep Creek ; and these consist of pieces of a 

 conglomei-atic, and sandy fossiliferous bed. The fossils are 

 represented by casts, internal and external, of corals, mollusca 

 and a tribolite, and their general aspect is that of the Yeringian, 

 or uppermost Silurian, faces. These fossils will shortly be dis- 

 cussed in a separate paper of this series.
