TABLE CaprE, TASMANIA. 
This section has been so fully described by Johnston, ‘“ Geol. 
Tasm.” that after a visit of inspection little can be added. But 
it is noteworthy that the bed richest in fossils is the basal one, or 
Crassatella-bed ; the overlying Turritella-bed, so called from its 
profusion of two small species of that genus, shows a remarkable 
poverty in species, while all, except ‘the few echinoder ms, are 
common to the Crassatella-bed. A gradual diminution in species 
and individuals arrests the attention as we rise in the section, so 
that at last the top of the Turritella-bed shows barrenness, and 
merges into unfossiliferous beds. No stratigraphical interruption 
from base to summit can be observed. 
The Turritella-bed has acquired exceptional interest from the 
fact that it has furnished the remains of a marsupial, and there- 
fore the most ancient as regards Australia. The study of the 
block stone containing this unique fossil does not permit of an 
explanation of its occurrence other than that of its embedment in 
original soft sediment. 
The Table Cape section thus presents most pronounced littoral 
deposits, gradually merging into a lacustrine formation. 
We append a list of fossils revised from that given by Mr. 
Johnston, and have indicated those for whose denomination we 
hold ourselves responsible ; and until actual comparison with the 
Aldinga types be made it will not be safe to accept those alleged 
to be in common with restricted species of the Aldingian basin. 
Mr. Pritchard’s paper on ‘Table Cape Fossils” only reached 
us a few days before this paper was read, so that its critical con- 
sideration is deferred ; but it may be stated that Mr. Atkinson’s 
collection, which forms the basis of Mr. Pritchard’s report, was 
studied and named by one of us in 1893, when on a visit to Table 
Cape, though it is evident that gentleman has since increased his
