316 AUSTRALIAN FORAMINIFERA, II., 



[The Miliolida^ in general flourish )>est in tropical seas, from 

 the shore to deptiis of 150 fathoms; and this family is exceedingly 

 well represented]. .. , 



(f) Cassidulina j^'ifkeriana is characteristic of tropical seas at 

 depths of 45-175 fathoms. 



(g) LagpAia favoso punctata is, according to the Challenger 

 Report, restricted to the shores of New Guinea and Torres Strait 

 at a depth of 17 to 155 fathoms. 



(h) Polymorphina regina is a shallow water form occurring 

 round the islands of the Pacific, to be found in Howchin's list of 

 Eocene foraminifera, but not in later Tertiary Australian 

 deposits. 



(i) The Rotaliid^ of our Table Cape material exhibit a striking 

 parallelism to the forms now occurring off Sydney Heads and 

 Byron Bay, especially as regards Truncatulina. Discorbina is 

 not an abundant form, and the species present are forms which 

 thrive best in warm latitudes. 



From a study of this material, the conclusion is unavoidable 

 that the material was deposited in Eocene times in a shallow sea; 

 and, furthermore, that in this period climatic conditions were 

 much warmer in the Tasman region than now. 



In conclusion it is necessary to mention that our attention has 

 been drawn by Mr F. Chapman, F.R.M.S., to the fact that 

 recent forms resembling Biloculina rinyens and B. bulloides are 

 referred to other genera on account of their internal structure 

 differing from the fossil forms for which the above-mentioned 

 names have been retained.^*' We have however not sectioned 

 any of the forms of Miliolidie enumerated in our lists, and have 

 therefore retained the well-known names of Biloculina ringens 

 and B bulloides; the retention of these names in our paper has 

 the advantage of making these lists consistent with other 

 lists of Australian Foraminifera such as Whitelegge's list in 

 " Invertebrate Fauna of Port Jackson and Neighbourhood," f
