belong to a higher horizon than those of Cape Stewart, and 

 further inland are yet newer deposits. 



The plant-remains of the lowest shales found at Cape 

 Stewart were examined by N. Hartz ^) who referred them to the 

 Rhætic or to the Rhætic-Lias formation. 



The animal-remains were examined by B. Lundgren^). 

 Lundgren states that the rocks in which the fossils occurred 

 may be relegated to two main types, the gap between them 

 being bridged over by other rocks of intermediate structure 

 and composition. The two main types are : — 



1) a somewhat calcareous, grey sandstone, rich in mica; this 

 is usually fine-grained, sometimes so compact as almost 

 to be designated a quartzite, at others containing rounded 

 quartz-grains and quite fresh fragments of felspar as large 

 as peas, the rock thus assuming rather the character of 

 a conglomerate. 



2) a dark-coloured, almost black, very calcareous rock, also 

 containing mica. 



In the grey sandstone, the following fossils were found: — 



Bhynchonella sp., three species. 



Waldheimia sp., two species. 



Ostrea grönlandica п. sp.^ one of the most characteristic 



forms, and fairly common. 

 Ostrea sandalina [cf. sandalina, Goldf.). 

 Placunopsis minuta п. sp. 

 Plicatida cf. spinosa, Sow. 

 Limea duplicata, Sow. 

 Lima sp.
