having a sub-triangular carapace, as seen from the end, and in 

 the surface pittings. The shape in side view differs materially 

 in that our species is broader anteriorly and narrower pos- 

 teriorly, the reverse of that seen in C. weUinytoniense.

THE FAUNA OF THE BATESFORD LIMESTONE. 



Preliminary Remarks. — The several records of species from 

 the Batesford limestone, comprising the foraminiferal and poly- 

 zoal rocks, are here collected in systematic form for facility of 

 reference. The corals, mollusca and some other groups of the 

 fauna have already been recorded by Dr. T. S. Hall, M.A.. and 

 Mr. G. B. Pritchard, B.Sc, F.G.S. ;1 whilst a new echinoid 

 Echinoneus^ and also I'entagona^ter^ have lately been added by 

 the former. Mr. Pritchard has described a new species of 

 Linthia, which until recently had been confused with McCoy's 

 '' Fericosmus yigas ' of the Murray River Cliffs.^ I myself am 

 responsible for the Foraminifera and the Ostracoda, which 

 groups are now described in detail for the first time ; one 

 species of the former group, however, had already been figured 

 and described in England by Messrs. Heron-Allen and Earland^ 

 under the name of Bigenerina conica, and Mr. W. Howchin 

 gave generic names to several forms recorded in Messrs. Hall and 

 Pritchard's paper referred to above. In the Spongida I record 

 spicules of calcisponges and identify the species of Isis as the 

 N. Zealand Tertiary form /. hamiltoni, which is, in Victoria, 

 a typical Janjukian fossil. Arm ossicles of f?) Antedon have 

 occurred in some of the washings of the disintegrated lime- 

 stone. The Cheilostomatous Polyzoa have been revised and 

 catalogued by Mr. C. M. Mapiestone in his list of Fossil Cheilo- 

 stomatous Polyzoa," and some new species of the Cyclostoma- 

 tous section have been described by the same author in a later
