248 FOSSILS FROM THE PALZOZOIC ROCKS OF N.S.W. 
vesicular structure, so that in all probability our examples are also 
referable to Khizophyllum, although from the much more contracted 
outline of the cone, as compared with L. (?) interpunctatum, I doubt 
very much if they should be referred to the latter. 
One of the three specimens is more Calceola-like than the other 
two, which again resemble Rhizophyllum to a greater extent, and 
remind us very much of &. Tennessee-ensis (Roemer). — 
One of the more pyramidal specimens exhibits several scattered 
tubercules over the convex side of the corallum, representing the 
bo 
broken and scattered bases of rootlets. In both these examples 
the calices are filled with irremovable matrix, but in the more 
Calceola-like form the characters are to a certain extent exhibited. 
The central primary septum is visible, bordered on each side by 
from eighteen to twenty crenulations alternately larger and smaller. 
Taking into consideration the difference in outline between our 
specimens and that of Prof. De Koninck, and the unsatisfactory 
figure of the latter, I am obliged to propose for the pepre ae
