Glenbumie road, and at Cemetery Hill road, which may for the 

 preseint be regarded as a passage bed between the two divisions, 

 or possibly a basement bed of the Yei'ingian, coDtaining Dalman- 

 ites meridianus at a higher horizon than usual. 



The majority of the fossils are represented either as casts in 

 mudstone or sandstone. As is often the case, the mudstone 

 casts a,fford veay perfect squeezes in wax, in which all the 

 minutiae of a well-preserved fossil may be made out, with the 

 additional advantage of structiu"e produced by weathering, and 

 not genea'ally seen in the thoroughly mineralised fossils. Thus 

 the vascular system of Atrypa reticularis is often shown with 

 surprising clearness in the mudstone casts from the Glenburnie 

 beds, and the same may be said of a species of Orthis (Rhipi- 

 domeUa) which occurs in the Merriang road beds, which shows 

 both muscular and vascular impressions.

 The numbers refer to localities so marked on map. 



Melbournian Series. 



I. — Yan Yean ; from the tunnel to lieserv^oir. 



Crinoids, indet. Columnars only, of a slender-stalked species ; 

 usually found in great abundance in a fine-grained sandstone. 



Chonetes melbournensis, Chapm. Found both in the sand- 

 stone and mudstone. These examples are smaller tha,n those 

 ' from the South Yarra mudstone. 



Nucula, s}).

?Phacops. 



Besides these forms I have already recorded from the same 

 locality, Hyolithes novdlus, Ban-., and BeJhrophon, sp., in addi- 

 tion to I'hacojJS and Encrinurus, whilst the Chonetes was pre- 

 viously referred to as Clionetes cf. melbournensis^.
