Numerous ostracods having the appearance of forms figured 

 by Chapman in the above-mentioned report were observed in tlie 

 material. 



In general it may be stated that the richness of the foramini- 

 feral fauna is indicative of warm water conditions of deposition. 

 Further, it is certain that the material was laid down at a depth 

 of from 50 to 150 fathoms. These conclusions are based on the 

 occurrence of forms which are restricted to warm zones and 

 shallow water, and to the complete absence of cold-water forms 

 such as Discorbina vesicularis which now flourishes in the same 

 latitude. 



There is a close correspondence between the Miliolidse of the 

 Table Cape fossil material and recent dredgings from Sydney 

 Heads and Byron Bay. The Table Cape fossil Nodosariinse 

 correspond closely with Howchin's Eocene list and those occurring 

 at Byron Ba)^ The abundance of Polymorphininaj indicates 

 deposition in shallow water (less than 200 fathoms). The 

 abundance of Polystomellinaj, and especially so of species which 

 <]o not occur at Sydney or B3^ron Bay now, but are restricted to 

 strictly tropical waters, as at Torres Strait and the Barrier Reef, 

 is itself conclusive evidence of warm-water conditions at the time 

 of deposition. 



Certain species found in the Table Cape fossil material deserve 

 .special mention in support of these statements; they are : — 



(a) Biloculina irregularis is a tropical species, which has only 

 been observed by us elsewhere in the Gulf of Carpentaria material. 



(b) Miliolina alveoliniformis is a coral-reef species confined to 

 shallow water. Occurs also in the Gulf of Carpentaria. 



(c) Miliolina rupertiana occurs only in shallow water in warm 

 latitudes. 



(d) Spirolomdina antillarum is a common form off the coast of 

 Brazil. 



(e) Spirolocnlina planulata and S. niticla are closely allied 

 species, the former being characteristic of temperate zones, the 

 latter replacing it in the tropical zone. Both are shallow water 

 forms, and both occur at Table Cape.
