TERTIARY CORALS. AT 
Sretion—WADREPORARIA PERFORATA. 
FamityY—WMVadreporide. 
Sus-FamiLy—EUPSAMMIN Ai. 
Genus—BALANOPHYLLIA. 
BALANOPHYLLIA GRANULATA, Duncan. Plate VII, figs. 1—5. 
The corallum is short, has a very large and encrusting base, and is constricted imme- 
diately below the calice. There is no epitheca, and the coste are large and very 
distinct." 
The calice is oval in outline, is compressed, and is marked by very small and equal 
costz externally ; it has a small columella and very numerous septa. 
The septa are delicate, wavy, and granular; there are six systems of them and five 
complete cycles, with half of a sixth. 
Very large, equal, rather wavy, flat, and rounded costz are seen at the edge of the 
base ; they bifurcate inferiorly* here and there, and are profusely granular, as well as con- 
nected by many cross bars. 
As the coste approach the constriction they diminish in size, become thinner, more 
numerous, and less granular, until, close to the calicular margin, they are almost linear. 
All are connected by the cross bars. The granules often are large enough to stand up 
well in relief. 
Height of corallum } inch. Diameter of base lird inch. Diameter (greatest) of 
calice &th inch. 
Locality.—Brockenhurst. In the collection of Frederick Edwards, Esq., F.G.S. 
The genus Balanophyllia (Wood) has received much attention since MM. Edwards 
and Haime’s ‘ Monograph on the British Fossil Corals’ was written. These authors have 
described in the ‘ Histoire Naturelle des Coralliaires’ (vol. 3) some new species. 
Since that work was completed Reuss has described three species from the “ lower 
marine sand” of Weinheim: and F. Roemer and Philippi have each discovered a new 
species in the fossiliferous beds of Latdorf. Moreover, the South Australian Tertiary beds 
contain species.
