The polyzoal rock at Flinders contains, besides polyzoa, numerous 
lenticular tests of Amphistegina 1 , but up to the present no examples of the 
genus Lepidocyclina have been there met with. In the present specimen 
from Cape Schancky however, in addition to numerous Amphisteginae y 
there are some occasional tests of Lepidocyclina tournoueri , identical with 
those found in the Miocene of Europe (Burdigalian) and in the Janjukian 
of Batesford 2 , and in western Victoria at Grange Burn.

Microscopic Structure of the Limestone. 
In thin section, under a moderately high power, this rock is seen f o 
consist of numerous polyzoan fragments, tests of Amphistegina , Operculina . 
Globigerina, Discorbina , and Pulvinulina , with occasional shell fragments, 
both bivalves and brachiopods, as well as sections of echinoid spines and 
plates. This organic fragmentary material is cemented into fairly compact 
rock by a fine, crystalline, grey mud. Where the peripheries of the fora- 
miniferal tests project into a cavity their surfaces are often coated with a 
minute fringe of calcite scalenohedra.
