a great Cyprcea {C. gigas), from the Murray River (Miocene) beds GALLERY 

 of Australia, which greatly exceeds in size the living Cyprcea 

 cervus from the Pacific, regarded as the largest living species. 5 & e. 



The foreign Cretaceous shells occupy Wall-cases 5 and 6. 

 There is exhibited here a fine series of Radiolites {Ilippurites)^ 

 shells allied to the existing Chama, which probably lived in 

 clusters adhering to coral-reefs in the Cretaceous sea. 

 They are rare in this country, but the ''Hippurite 

 limestone " is well developed in France, Spain, and

Italy, and it often occurs in the East and West Indies, etc. On 

 the wall are exhibited specimens of Inoceramus expansus from 

 Cretaceous beds in Natal, South Africa. In the wall-case are 

 placed shells of Alectryonia ungulata, Neithea quadricostata, Pinna 

 cretacea ; large Nerincea from Spain ; with Cucullcea, Inoceramus, 

 Gervillia, Trigonia, etc. Numerous beautiful examples of Trigonice 

 are here exhibited, ranging from the Lower Lias to species living 

 at the present day off the coast of Australia. 



The next case (No. 7) contains the series of foreign Oolitic Wall- 

 shells. There is a fine series (part of the Tesson Collection) ***^® 

 from the Lower Oolite of Normandy, agreeing closely with those 

 from British localities of a similar age. Amongst the Gasteropods 

 are Trochus, Neritopsis, Amherhya, Nerita, Pleurotomaria, etc., the 

 bivalves being represented by Astarte, Trapezium, Opis, Trigonia, 

 Pholadomya, Ceromya, etc. 



The succeeding wall-cases (Nos. 8 and 9) contain the Mollusca Wall-cases 

 from the Lias and Trias, followed by the Palaeozoic Beries, Permian " * *• 

 to Silurian. Lithotrochus Sumholdti, from the Lias of South 

 America, and Trigonia navis, from Germany, may be referred to.
