like, angles towards the other end. The axis of our living species 
is about 7 inches long and about 1 line in diameter, and, like the 
European living genus Pennatula, it has the quadrangular portion 
below, gradually assuming the circular section in the upper half, 
while our gigantic fossil prototype, like the European Tertiary 
extinct genus, Graphularia, has the circular portion below, and the 
longer upper portion quadrangular. I refer our fossil therefore to 
Graphularia, although it as much exceeds the European Tertiary 
Graphularia Wetherelli in size, as it does the living analogues. 
From the form of the conical lower portion, becoming quadrate 
after 3 or 4 inches from the conical lower pointed apex, and the hard 
surface and radiatingly crystalline structure so nearly resembling 
a Belemnite, and so nearly agreeing with the object described by 
Professor Tait as a Belemnite from the Tertiary beds of the same 
age as ours in South Australia, I cannot help thinking that, as the 
phragmacone has not been observed, the supposed discovery of that 
common Mesozoic genus of Cephalopoda in Australian Tertiary 
strata may be founded on a similar zoophyte, with a different rate 
of tapering, but of a generic type recognised as Cainozoic. 
To show the structural identity, I have figured the recent and 
fossil axes together on our plate, reversing the natural position of 
the recent one, which is represented with the upper end downwards, 
so that the transverse sections—circular, subquadrate, and promi- 
nently four ridged, with concave sides—may be compared with the 
correspondingly shaped sections of the fossil. The four longitu- 
dinal ridges corresponding to the four angles of the tetrahedral 
section usually present a slight spirally oblique twist, reminding 
us of the recent genus Umbellularia. 
T am indebted to the Rev. Mr. Legge, of Brighton, for my first 
knowledge of this interesting fossil, which he found in some abun- 
dance in the Waurn Ponds quarries, where, under the name of 
“ square bones,” they had attracted the attention of the workmen. 
At Mr. Legge’s request, instead of dedicating the species to himself, 
I have named it after his late wife, who always took a great interest 
in his geological investigations and scientific expeditions generally.

Geelong, and in similar beds (A* 22), Bird Rock Bluff.
