colony; for without a moment wishing to do away with that 

 principle of free-trade in scientific research that we all so 

 much rejoice in, or desiring to make any undue claim for 

 protection to native industry in Victorian geology, 1 think 

 you will agree with me that it is but right that we should 

 try to take inventories of our own possessions for ourselves, 

 and not leave it to outsiders to do it for us. 



The following is a list of the Lilydale fossils that have 

 been so well described by Mr. Robert Etheridge, jun., Govern- 

 ment Paheontologist of New South Wales, in Nos. 8 and 7, 

 Vol. I, of the " Records of the Australian iMuseum," there:— 

 Favosites grandipora, Trochus (Scalietrochus) lindstromi, 

 Niso (Vetotuba) brazieri, Cyclonema australis, Cyclonema 

 lilydalensis, Plianerotrema australis.. Oriostoma northi, Mur- 

 chisonia attenuata (i), Bellerophon cresswelli, Ambonychia 

 poststriata. In addition to these, Mr. Etheridge records, 

 without describing, the well-known and world-wide Silurian 

 brachiopod, " Atrypa reticularis," and mentions also that there 

 are three species of the well-known Rhizopod " Strom atopora" 

 yet to be described. The fossils which I myself wish to 

 record, as also occuiring in the Lilydale limestone, and as a 

 supplementary list to that supplied by Mr. R. Etheridge, 

 iun., are the following : — 



MOLLUSCA AND MOLLUSCOIDEA. 



Cephalopoda. — Orthoceratites, sp; ; a«id Discoceras? sp. 



Bellerophontldw. — Tremanotus pritchardi. 



Gasteropoda. — Eunema etheridgei, Stomatia antiqua, 

 Tryblidium (Metoptoma) nycteis, Pleurorhynchus (Oono- 

 cardium) costatus, and Pleurorhynchus (Conocardiura) 

 bellulus, Naticopsis lilydalensis. 



La7)iellibranchiata. — Ambonychia tatei. 



Brachiopoda. — Strophomena rugosa, Leptcena transver- 

 salis, Orthis elegantula. 



CCELENTERATA. 



Actinozoa. — Heliolites, sp. ; Cyathophyllum, sp. 



Some of these names will at once be recognised as being 

 those of world-wide Upper Silurian forms, but the following 

 .species are new, as far as my knowledge goes, and so I
