Genus EURYPHYLLUM Hill. 
Euryphllam Hill, 1937, p. ir>0; 1937, a, ]>. 50; 1938, [). 25. 
Genotype : EiiryphyUnm reirU Hill, 1937, ]». 150 ; 1937, a, p. 50 ; 1938, 
p. 25 ; Permian (? Artinskian) Htiwen Marine series of Queensland. 
Diagnosis : Siin|>le, turbinate to eeratoid Rugose corals, erect excej)t at 
the tip, which is turned aside ; with woll-inarkod interseptaJ ridges, and 
ty|)ically an obii(|ue calical floor. The major se|)ta, which arc never carinate 
or seiTate, exttaid to the axis and are pinnately grouped about a long, closed 
fossida, bisected by a long canlinal septuui on tlio concave side of the cornl- 
lurn ; alar fossulae are [H'esent- Tijo septa are dilated, and at hrs-t arc laterally 
contiguous throughout, l>ut iluring ontogeny dilatation decreases in a widen- 
ing zone midway betw(>en tlie j^eriphery and the axis, leaving a w ide peripheral 
stereozone, and an axial structviro hu’med by the conjoined <lilat.ed axial ends 
of the se])ta. Very short minor septa apj^ear late, and remain ))uried in the 
stereozone. Tabulae are distant, usually dilated, c<.)m|)lete or incom])Iete, 
and there are no disse])iments. 
Euryphyllum reidi Hill. (Plate 1., tig. 3 ; Plate Tl,, fig 2.)

skian) of Queensland. 
Holotype : F324-3, University of Queensland collection, from the ?Artinsk- 
ian Upper Dilly Stage of CVibbagc Creek. S|n*ingsure District. 
Diagnosis : EEurypfiylkttn with obli()uc calice, the cardinal (piadrants 
being wider than the coimter ; the peripheral stereozone is irregular and 
very wide, and septal dilatation does not decrease until very late. 
Remarks on Norf^i-Western Austrfdi-an Specimens ■ There arc in the 
Collection of the University of Western Australia, 5 specimens from tlu^ Stropfui- 
Losia-Calceolispongia horizon, just below the horiz(jn with Allotriopliylhun, .sp., 
middle CalceoHspongia stage, 1 spo(djTicn from the horizon just below the 
Dictyoclostus grafiosus zone, upper CalceoHspongia stage, (» speeimens from 
just above the “ w^orm track ” horizon, upper (tilceolispongia stagts all from 
the east limb of the s^Tudine west of (Molkilya Pool, Minilya River, and 1 
sp(5cimen from the main CalceoHspongia liorizon, (> specimens from the Oleio- 
thyridina-Calceolispongia liorizon, all from the up 2 :)(U' CalceoHspongia stage, 
west limb of the same syncline. The specimens on the w hole arc rather larger 
than those from the Springsure ari^a, but thosii from the first named horizon 
are identical in size with Queensland S])oeimcns From Castk^ ('rct^k, Th(>odore. 
The species may prove divisible. I havti not yet mafle a tietailed study of 
zaphrentimorphs from the Upper Marine of Now South Wales, but from 
Etheridge’s figures none aj^ipears to be K. reidi^ tliough Z. grcgoriana is possibly 
a member of the genus. 
Thirteen sjjecimens from the highest CalceoHspongia horizon, at th(^ toj> 
of the Wandagee series, are identified as Eiiryph.ylluni reidi Hill. They are 
of the morphology of that sub-group from Castle Creek, Queensland, and from 
the locality 3 3, in tlio middle or ii 2 )])er parts oF the CalceoHspongia zone in the 
Wandagee Series, west or south-w'est of ('oolkliya Pool, Minilya Riv^er. The 
localities of these 13 thirteen specimens are : — 
south-w'est side of Wandagei^ Hill, neai- montli of South-West Creek ; 
near south-east corner of Wandagee Hdl, at crossing of Wandagee Wool- 
shed — Middalya road over highest CalceoHspongia horizon ; 
north-east corner of Wandagee Hill.
