Ohs. The presence of the genus Placuna in the uppermost Mesozoic Beds of 
Queensland is shown by the occurrence of a small shell, one and a-quarter inch wide by 
the same in height, wdth a nearly straight cardinal margin. The specimen is only an 
impression, jjossibly of the interior of the right valve, and shows the indentations left by 
its own diverging teeth, and the impressions of the teeth of the opposite valve. There 
are also traces of the shoehorn-shaped muscular impression, but there is no sign of any 
pit between the “ cartilage fulcra.” 
The transverse outline of this species renders it a peculiar one, as it is more or 
less equal to the vertical measurement.

Lima (Eadula) Eandsi, sp. nov., PI. 21, fig. 13. 
8p. Char. Shell obliquely ovate, more or less compressed, very slightly alate 
posteriorly. Hinge-line very short, straight, and horizontal. Anterior side rounded, 
alate above, margin convex ; posterior side small, verj’^ slightly alate, with a convex 
margin, slightly emargiuato above ; posterior slope sharp ; ventral margin obliquely 
rounded. Umbones moderately acute, apparently incurved. Surface bearing as many 
as fifteen (twelve to fifteen) broad, to some extent flattened, radiating ribs, with at 
times traces of a few shorter interpolated costa), separated by flat interspaces, con- 
siderably wider than the width of the ribs, crossed by delicate concentric lamellae ; the 
anterior and posterior wings, and the sides of the valves contiguous to them, are devoid 
of ribs. 
Obs. This shell, although allied to Lima Gordoni (PI. 24, fig. 16), is believed to 
be distinct. The costas of the former are much more numerous, the margins of the 
shell are quite differently curved, and there docs not appear to be any pronounced 
hinge-line. L. Gordoni is also much more obliquely produced towards the posterior 
side. A fragment of another specimen would seem to show that some of the ribs on 
the anterior side were spinous at their front edges. 
From the shell T have called Oxgtoma rockwoodensis (PI. 24, fig. 15) the present 
differs in a less convexity, altogether different posterior wing and umbo, and by 
possessing radiating ribs thicker and more obtuse. Our species resembles a shell 
figured by Conrad as Lima leonensis,* but is less oblique.
