No less marked is the want of community between the Permian marine 
fauna of eastern Australia and the preceding Lower Carboniferous fauna.

in the argillites of the eastern portion of New Caledonia, while farther west, 
in the gritty littoral beds of the same formation, there are the typically 
Tethyan cephalopods Waagenoceras, Stacheoceras, and Popanoceras, which 
n New Zealand also is a faunula showing Australian affinities, though 
containing nothing typically Tethyan. Trechmann (1917) described from

to the form occurring in the Permian (“ Carboniferous ”) rocks of Hobart, 
which R. M. Johnston termed Inoceramus elegantula, though his illustration 
of it (Geol. of Tasmania, pl. xv, fig. 13) does not suggest affinity with either
