Mr. 'W. H. Eaiicls has found a second specimen, convex and round, and generally 
like the above. It has a small umbilicus, but the other characters are obscure.

Family— COCHLIODONTID^. 
Genus— DELTODUS, L. Agassiz, 18.59, M.S. 
(Enniskillen Collection.)* * * § 
Deltodfs ? A 1 JSTEAEIS, sp. nov., PI. 39, fig. 11. 
Sp. Char. Oblong- triangular, insensibly flattening towards the broader or 
anterior end. The outer side is thickened, and obtusely rounded, the outer or base thinner 
and sharper. Anterior margin gently rounded, the posterior end gradually acumin- 
ating, and more or less obtusely so. The surface gradually decreases towards the basal 
and anterior margins, and is traversed almost medianly by a rather curved, wide, deep 
sulcus, narrower at the basal than the outer end, and followed in the direction of the 
anterior end, by two other parallel and indistinct depressions. Structure open and 
porous. Section semi-circular, abruptly so on the outer side. 
Obs. With the exception of the Tomodus convexus, Ag., figured by Prof. De 
Koninck, from the Permo-Carboniferous of New South Wales, this is the only Cochlio- 
dont known to me from this portion of the Australian Palieozoic rocks. I do not feel 
at all certain that the reference to Heltodus is a correct one, but in the unsatisfactory 
state of our antipodean scientific libraries, I am unable to make a more exact determina- 
tion. If a species of this genus, it approaches T). aliformis, McCoy, but is much more 
regular in outline, and lacks the contracted posterior end of that species.

Order-GANOIDEI. 
Family— PALAONISCID.F:. 
Eemains of a Palseoniscid fish have been presented to the Mining and Geological 
Museum, Sydney, by Mr. C. T. Musson, F.L.S. “ from a ridge half a mile from and 
to the north of the Bogantungan Eailway Station,” Drummond Eange (= Star Beds).! 
From the same locality the late Mr. James Smith made a large collection of fish- 
remains, which I have not yet had an opportunity of examining. 
Mr. Bands has also recently discovered the remains of a fish in the Star Beds 
near Lornesleigh Station. § It certainly belongs to this family, and, so far as the want 
of the head will permit an opinion to be formed, it appertains to the genus Falteoniscus.
