52 CRETACEOUS CORALS OR ARTHOZOA 
2. Eupsammia denotata, StoUczha. PI. XI, Figs. 8 — 9. 
Eups. corallmn inverse eonoideimi, hasi altenuatum, lenle curvatiim, theca mnrali 
incrassata indutiim, costatmn, costis ccqiialihus, snlcis mtilio angiistiorihus seqxiratis, 
simpUcihus, snlco quoqne circiter trihus serichus granorum composUo; sepitis temiissimis, 
in sex cgclis disposifis, modice conjlueniihiis, cyclo ultimo imperfecto ; sectione coralli 
rotiindate elliptica ; columella tenuiter sqmigiosa, circiter quartam partem totius 
diametri lata. 
I have only two rather imperfect specimens for examination, hut they appear 
to belong to a well marked and distinct species. The form is rcA'crscly conoid with 
a roundly ovate section of the corallum, the perfect calj’x has not been observed. 
The mural theca is of great thickness, and the costee, each apparently composed of 
about three series of granules, which arc comparatively broader than in Eups. 
various. There are six cycles of septa present, but the last is incomplete; all 
arc very thin, undulating, but not very iiTegular. 
Locality. — North of Odium, in a yellowish limestone. 
Formation. — Ootatoor group. 
Family ^ — P OFITIDyF. 
The members of this family are characterised by their compound coralla being 
entirely composed of a reticulated sclcrcnchyma ; the single individuums arc directly 
connected by a spongiosc mural theca or a porose coenenchyma, and are propagated 
by an cxtra-calicular gemmation; septa small, but otherwise well developed; visceral 
cavity with dissepiments, but never sub-divided by tabulm. 
Species of this family are found both fossil and recent. They are represented 
in South India by a single species, belonging to M.-Edwards and Haime’s* sub- 
division roRinxM, in which the coenenchyma is very slightly or not at all developed. 
XXV. Genm.' — COSCIXAR/EA, MUne-Fdwards and FLaime, 1848. 
Massive coralla of a dense tissue and without an epithcca ; calyces concave, 
with Avell developed septa and without pali, directly connected with each other by 
the septal costm. 
The type of this genus is Q. mceandrina, Ehr., fC. Lottcc, M.-EdAvards and 
ilai me), a recent species from the Red Sea. The authors of the Hist. Nat. des 
Corail. (loc. cit.) also refer to the same genus Re us s’ Porites mammillata\ from 
the Gosau deposits, and a very closely allied, if not the same, species also occurs in 
South India.
