is included in Messrs Hall and Pritchard's paper. i The forms 

 enumerated are, Orbitoides^ mantelli, Ainphistegina sp., Oper- 

 culina sp., and Gypsina sp. 



The shallow-water nature of this part of the fauna of the 

 limestone is shown by the occurrence of the minuter forms of 

 foraminifera usually inhabiting areas close to the shore-line, as 

 PolystomeUa crispa, Truncatulina Inhatula, iVoiiioiiina boueana, 

 Hotalia calcar, and lastly and most important, by the compara- 

 tively large discoidal forms, Cyclocypeus and Lepidocyclina. 

 In connection with this same group of organisms, it is of addi- 

 tional interest to note that several species first described by 

 Dr. H. B. Brady from the " Challenger '' collections, dredged in 

 and peculiar to Australian waters, occur in these beds of com- 

 paratively remote age ; so that these particular species have 

 been persistently local from at least Miocene times, whilst some 

 are also present in homotaxial beds in Europe, as the Miocene 

 of the Vienna Basin. 



Through the detailed results of Mr. Howchin's work on the 

 foraminifera found elsewhere, we are enabled to make a general 

 comparison with other tertiary foraminiferal faunas of southern 

 Australia. TIjus many of the smaller and commoner species 

 recorded for the first time from these beds have previously oc- 

 curred in the Balcombian series of the Lower Muddy Creek beds, 

 and in strata of similai- age in the neighbourhood of Port Phillip. 



The ostracoda are nearly all of living species, and two are 

 even now found in the Southern Ocean, off the Australian 

 coast, viz.. Bairdia foveahita and B. aiuyi/daloidex. These and 

 other forms indicate a moderately shallow-water ha))itat.
