88 FURTHER REMARKS ON AUSTRALIAN STROPHALOSLE ; 
as written, I defined three species. The first of these was 
Productus Clarkei, Etheridge ; the second, a form to which I gave 
the name of S. Jukesti; whilst the third was King’s 8. Gerardi. 
These I described fully, according to the material then at my dis- 
posal, and made the following remarks :—“ Tt would not surprise 
me if, eventually, we have to unite the shells now described as 
Strophalosia Clarkei, Eth., 8. Gerardi, King? and 8S. Jukes, 
Eth. jun., in one variable species, although, as I have before said, 
such a proceeding would be premature, as the material to hand is 
not suflicient in itself.”' Since the above was written I have not 
Seen any evidence to justify a union of . Clarkei with S. Gerardi. 
On the contrary, Prof. Liversidge’s specimens, from the structure 
to S. Gerardi. The resent notes can only be looked upon as& 
further contribution to the solution of this interesting question, 
which must still remain an open one.

FOSSILS FROM THE CRETACEOUS ROCKS OF NE 
AUSTRALIA. 
Prof. Liversidge has also forwarded a few fossils from the cre- 
taceous rocks of N. FE. Australia. The specimens appear, from 
their external appearance, to be portions of boulders (or rounded 
blocks), and comprise Bivalves and Cephalopoda only. 
The Bivalves consist of two species of Inoceramus, an Aucella, 
and possibly a Monotis, or allied genus, 
The great variability of the shells forming the genus Inoceramus 
renders it very difficult to decide on the specific identity of its
