periiilieiy, usually curved outwards, becoming wider apart on their iiiAvard 
extension, and passing across the intersejjtal loeuli direct ; dissepimental 
vesicles small and irregular in shape in the outer zone, more or less quadran- 
gular in the more open portions of the loculi ; fossula large, extending nearly 
lialf across the corallum ; cardinal septum short. Tahulce Avell developed, 
close to one another, somewhat less than half the diameter of the corallum in 
width, horizontal or gently rolling. Epitheca moderately thick, concentrically 
lined; ruga) hid by the epitheca, corresponding to the interseptal loculi. 
Ohs . — The genus Campoplnjlliim has not hitherto been recognised in 
Australian Carboniferous or Permo-Carboniferous rocks, although it is known 
to occur both in the Devonian of New South Wales and Queensland. 
The present speeies is a well-marked member of the genus, and possesses 
a copious development of tabuhn (FI. IX, Eig. 18), which lie very closely 
together — in fact, are almost in contact— and usually with a gently-undulating 
outline. In the absence of any dehnite curvature of the corallum, the fossula 
has been assumed to be dorsal, the cardinal septum being short, and extending 
but a Inief distance into it. 
Locality and Horizon . — Einge Berry, Itouchel Brook, Hunter PJver, 
County Durham {C. Cullen) : — Horizon doubtful, but perhaps Carboniferous. 
Group — Cyathophylloidea. 
Family— C YA TROFHYLIAHJE. 
Ohs . — A coral referable to this family, and described by Professor De 
Koninck as Cyathophyllum inversund, found at Colocolo, has not come l)efore 
me, but from its peculiar specific characters should be easily recognisable — 
indeed, these are of such a nature as almost to warrant its exclusion from the 
genus Cyaihophyllum ; nor have I seen his Cyathaxonia minuta- from Burra- 
good. Two other species were also described, Lithostrotion hasaltifornie^ and 
L. irregular , on which it is necessary to make a few remarks.
