CEETACEOUS CORALS OR ANTHOZOA 
CoMOSEKis Oldiia.miaxa, Sloliczka. PL X, Eig. 3. 
Comos. corcdlum brece, irregularlter suh-rotunclate explanatim, siqv'ci con- 
vexinsculmn, calycibus numerosis, parois, iderimque uniseriaUbus, sed irregulariter 
disposills, jugis inodioe elecutis, angulatis et irregulariter conjluentibus separatis 
instructum ; septis crassis, sub-cequalibus, granulalis, lateraUterque spinulutis, in 
tribus cyclis dispositis, cyclo tertio sceqdssime imperfecto, omninis ad medium sensim 
attenuatis atque inter se plus minusve dktincter conjluentibus; columella parva sed 
distincter spougiosa. 
This species has a remarkably close resemblance to the Jurassic C. irradians, 
the corallum being irregularly ovately expanded, slightly convex above, and very 
shortly pedunculate below. The single specimen as yet known has scarcely any 
traces of the epitheca preserved ; it is only indicated by irregularly concentric swel- 
lings, and the entire surface shows instead a radiating striation. The ridges on the 
upper side are rather sharply angular, moderately elevated, and quite irregularly hut 
rather closely confluent. The calyces situated in the depressions are uniserial, 
small, with a small and distinctly spongiose columella. There are three cycles of 
septa, those of the last being very often incomplete, their total number varying from 
18 to 24 ; they differ only slightly in strength and are rather coarsely granular. 
Both the calyces and ridges are almost equally numerously distributed over the 
entire upper surface. 
Locality. — North-west of Moraviatoor, in a brown limestone ; only the figured 
specimen has as yet been fonnd. 
Formation. — Ootatoor group. 
Family , — C Y CL OSERIDjF. 
Fromeiitel, Pal. Fran 9 . terr. cret., viii, 1867, p. 323. 
The CvCLOSERiDyE include simple coralla, covered with an epitheca, the costae 
on it being granular, bmnehing and often anastomosing ; the septa are numerous, 
thin, sub-equal, granular or dentate, and connected by synapticulae. 
Eromentel (1. cit., p. 325,) distinguished fourteen genera, out of which only 
two occur in South India, Thecoseris being represented by one and CycloUtes by 
four species. 
XXII. Genus. — THECOSERIS, Fromentel, 1869. 
Comp. Pal. Fran 9 . terr. cret., 1870, tom. viii, p. 367. 
Corallum more or less regularly turbinate, pedicellate, sessile, provided with 
a well developed epitheca ; calyx flat or moderately convex, impressed in the centre ; 
septa very numerous, equal or sub-equal, thin, serrated or dentated at their upper 
edges, sometimes anastomosing, meeting in the centre of the calyx without forming 
a columella.
