lYith regard to the identity of Fentadia reniformis and P. trigoncO, 
I am not at present able to offer any suggestion. 
Another marked peculiarity in the casts of P. KonincJd is the line of 
small nodes along the hasi-radial and inter-basal sutures (PL XVI, Pig. 2), 
also to some extent visible in De Koninck’s figures. Do these represent 
vacuities or depressions along the articular margins of the plates, in which 
were lodged fibre-bundles for the firmer union of the plates, otherwise loosely 
articulated ? 
In P. palens, Trautschold, each radial is succeeded by two costals, 
the second lieing axillary. In the present species, however, judging from the 
cast, there appears to T)e three, with the third axillary. 
The fine example represented in PI. XVI, Pig. 1, was collected by 
Mr. E. P. Pittman, Government Geologist.

Sj). Char. — Calyx very large, gloliular-globose, with a protuberant 
base, on Avhich the calyx rests when placed in its normal position ; greatest 
periphery about the basi-radial sutures ; sutures all deeply marked ; plates 
very thick. Infra-basals forming an expanded shallow cup visible in a side 
view, the left antero-lateral the larger. Eadial plates very large, their 
convexity so slight that the surfaces present a more or less flattened 
appearance. Costals strong and massive, the radio-costal sutures gajnng ; 
in the anterior ray the first costal transversely triangular- quadrate, second 
transversely tabular ( ? axillary), succeeded by three sub-alternate more or 
less triangular smaller pieces ( ? distichals), the third of which is axillary ; 
succeeding pieces ( ? palmars) thick, alternate, and triangular. Column of 
large joints. Sculpture none.

’ Prof. L. Cl. cle Koninck gives as the original locality for this species, Osterley, Hunter River (Foss. 
Pal. F~ouv, -Gaiks du Slid, Pt. 3, 1877, p. 166). Osterley is three miles from Hinton.
