A glance at the so-called species of Sangninolites described * from the Carboni- 
ferous beds of N^ew South Wales by Professor De Koninck {S. EtJieridgei, 8. MitcJielUi, 
8. MeOoyi, and 8. Tenisoni), will show how little resemblance they bear to the Queensland 
fossil. Of them, 8. MoCoyi is certainly more nearly allied to the latter than any of the 
others. It has the outward apj)earauces of the genus Allovisma, King,t but without a 
better knowledge of its internal characters it would not be wise to so refer it. It is 
certainly clear that, like the latter, it possessed an external ligament, but the impression 
of the jJallial line is not retained. Again, the valves are more convex than is usually 
seen in AUorisma.

Edimndia obovata, Etheridge, Quart. Journ. Geol. Soe., 1872, xxviii., p. 328, t. 13, f. 3. 
8p. Char. “Shell ovate, anterior margin convex, or nearly circular; posterior 
margin slightly truncated ; hinge-line nearly straight ; umbones small, close to anterior 
side ; ventral margin almost parallel with dorsal ; outer shell wanting, but appears to 
have been concentrically banded.’’ {Etheridge!) 
Obs. This species was compared by Mr. Etheridge to Pullastra ovalis, McCoy, 
and Edmeniia ? compressa of the Irish Carboniferous System. 
It is an extremely difficult matter appropriating these indistinct casts to their 
proper genera. The present specimen is certainly not a ilgacites, as alternatively 
suggested by its describer, nor does it agree well even with the characters of Edmondia. 
The figure seems to me to agree much more with the outline of the last genus, 
Gheenomya ?, than it does with either of the foregoing.

Edniondia conccntrica, Etheridge, Quart. Journ. Geol. Soc., 1872, xxviii., ii. 328, t. 13, f. 2. 
8p. Char. Transversely elongated, oblong, valves rather compressed, hollowed 
uu the flanks. Cardinal or dorsal margin straight posteriorly, inclined obliquely at the 
s-uterior eud ; ventral margin convex anteriorly and posteriorly, straight medianally. 
Anterior end long, narrowed, and flattened ; posterior end longer than the anterior, with 
^ semi-truncate margin; posterior slope very much flattened, hardly defined by any 
diagonal ridge, and entire. Umbones inconspicuous, depressed, sub-median in position. 
Surface with numerous concentric linos of growth, arranged in band-like zones, distant 
^rom one another.
