UNRECORDED GENERA OF THE OLDER TERTIARY FAUNA. 195 
slightly sloping to the somewhat deeply seated peristome. The 
peristome is central, transversely oblong, with bluntly pointed 
bourrelets. Periproct is transversely lunate, inframarginal, the 
superior border just touching it. The ambulacra are long, 
narrowly open, the anterior is the shortest, and the postero- 
laterals are the longest ; zones of paired pores are flush or very 
slightly sunken, extend to near the ambitus and show a tendency 
to inequality of length. Ornamentation of small imperforate and 
apparently noncrenulate tubercles in sunken subpentagonal scro- 
bicules, which are very close together but not discontinuous. 
Height 24, length 57, breadth 54, major diameter of periproct 8 mm. 
Locality:—Eocene: Table Cape, Tasmania. 
Genus Cardiaster. 
This Cretaceous genus has been extended in its range by the 
discovery of two species in the Eocene beds of the Aldinga Cliffs, 
viz., C. tertiarius, Gregory, and C. latecordatus, Tate ; and though 
the announcement of its occurrence in the Eocene fauna of South 
Australia was made as early as 1877 (Q. J. Geol. Soc. Vol. xxxut. 
p. 257), yet by an oversight it was omitted from my ‘ Census.” 
Genus Cyclaster, Cotteau. 
The species included under Micraster and Brissopsis are one, 
which is referable to the above named genus as I have already 
indicated (Trans. Roy. Soc. 8. Austr., 1892, p. 193). 
Genus Gualteria. 
Is represented in our Older Tertiary by G. australie, Cotteau, 
“Mem. Soc. Zool. de France, 1890.” 
Genus Rhynchopygus, Duncan. 
This generic reference must be expunged, as it was applied by 
Duncan to a distorted example of his Holaster australia. 
Class ZOANTHARIA. 
Genus Astrangia. 
ASTRANGIA TABULOSA, spec. nov., Pl. xiii, fig. 2.

ccenenchyma, which consists of thin bands supported by extremely
