CRETACEOUS CORALS OR ANTHOZOA 
or 27 longer septa which originate in the fossula, and about as many shorter ones. 
In some places a third series of still thinner ones begins to appear, but its septa 
are, as a ride, not very distinctly traceable. The base is concave and appears to 
liave been smooth. 
An allied species was described by Fromentel (Pal. Eran 9 . terr. cret., tom. viii, 
p. 359, pi. 03, fig. 3,) from the Gault or Upper Greensand deposits of Sainte Croix 
under the name of C. Saiictcc-c7'i(cis ; it differs from the Indian form by having 
somewhat fewer and more equally strong septa, and a much smaller fossula, almost 
only represented by a central pit. 
Loccdily . — Near Yeraghoor, in a greyish sandstone.

MADREPORARIA PERFORATA. 
Family, — MADBEF OBID^E. 
Milne-Edwards and Ilaime, in their Ilist. Nat. des Coralliaires, vol. iii, p. 99, 
divide the whole of the Anthozoa PEREORATA into two families, the Mabzeforibje 
and the Bojiitidm. The former is sub-divided in three sub-families, the EursAimixjE, 
Avithout independent coenenchyma, the MABREroniEJE and the tuebixarieje, with 
coenenchyma, but the former has the septa unequally, the latter equally developed. 
Sul-family.— EVFSAMmNjE. 
This sub-family includes, according to Milne-Edwards and Ilaime, simple 
and complex forms, the single coralla being without an epi theca ; the septa arc 
AAnll developed and distributed in six systems, the septa of the third and subsequent 
ordei’s are generally united by pairs, or in a greater number among themselves ; the 
columella is spongiose or granular, and the walls arc subcostulated, granulated, and 
perforated. 
The EERSAMMiK^ are represented in the South Indian cretaceous deposits by 
two species, apparently belonging to the typical genus Eupsanwiia, which has, I 
think, as yet only been known from tertiary deposits. 
XXIV. EUPSAMMIA, Mihie-Edioards and Uawie, 1848. 
Corallum simple, sub-cylindrical or obconic, free, without any lateral mural 
expansion ; calyx ovate or rounded, and of moderate depth ; septa rather thin, 
laterally granular, generally irregular, in four or fiA'c cycles, sometimes aa ith indica- 
tions of a sixth one ; columella well developed ; costoe numerous, simple, extending 
the entire length of the corallum from the base, composed of fine but somewhat 
irregular granides.
