FOSSILS FROM THE PALZOZOIC ROCKS OF N.S.W. 251 
Genus PLEUROPHORUS. King, 1844.

Pleurophorus Morrisii. De Koninck. 
Orthonota? costata. Morris. Strzelecki’s Phys. Deserip., N. 8. 
Wales, 1845, p. 273, t. 11, f. 1 and 2. 
Pleurophorus Morrisii. De Koninck. Foss. Pal. Nouv.-Galles 
du Sud, 1877, pt. 3, p. 281, t. 20, f. 5. 
Obs. A small example of this species much incrusted with matrix, 
but with the shell -preserved. ave not seen the internal hinge 
characters, but the general configuration would bear out Prof. 
De Koninck’s reference to the genus Plewrophorus rather than to 
Orthonota. 
Loc.—Wollongong, in sandstone ; Carboniferous, or Permio-car- 
boniferous ? 
Genus APHANAIA. De Koninck, 1877. 
(Foss. Pal. Nouv.-Galles du Sud, pt. 3, p. 302.) 
Obs. One valve of a shell before me (Figs. 3 and 4) appears to 
correspond to some extent with the characters of this genus, 
though not equally so with either of ies 
Aphanaia, by Prof. De Koninck. From A. Mitchelli (M‘Coy, sp ) 
it may be distinguished by the want of the or alate 
of resemblance between our shell and De Koninck’s Mytilus Big sbyt. 
Further specimens are required before this form can be definitely 
determined. 
Loc.—W ollongong, in sandstone. 
Class—G-ASTEROPODA.
