CRETACEOUS CORALS OR ANTUOZOA 
VI. Genus. — EPISIMILIA, Fronienlel, 1859. 
Corallum sub-cylindrical, or more or less compressed and conoid, attenuated 
at the base or shortly ijcdicellate, covered vith a n'ell developed epitheca, the costae 
being indistinct ; the calyx is ovate or round, according to the form of the stem, 
apparently very slightly concave in the centre ; the septa are in six systems, smooth 
or nearly smooth at the sides ; dissepiments abundant ; no columella is present. 
I liave slightly altered Eromentel’s characteristic, because it appears to have 
been framed almost only with reference to the two species which that author de- 
scribes. IVlien the rounduess or slight compression, or a more or less pedicellate 
shape, of the corallum is not considered to possess generic value in the case of 
Trochosmilia, JPlacosmilia and others, it is only a natural consequence not to admit 
it in the closely aUied Epismilia. 
The genus differs from Trochosmilia by its well developed epitheca and laterally 
smooth or nearly smooth septa ; the last character also separates it from Montli- 
vauUia. It includes a few Jurassic and two cretaceous species, to which one is 
added from South India. 
Epismilia crassisepta, Stoliezica . PI. II, Figs. 8 — 9. 
Epism. corallum suh-cylindraceum, vel obverse conoideum, crassum, basin versus 
angustatum, ad intervalla irregiilariler consirictum, brevissime atque abrupte pedi- 
cellatum^ basi arcuata vel torta ac angusta affixum ; epitheca rugtdose striata; calyce 
rotundato, paulum exserto, ad marginem sxih-rohmdato, medio impressiuscido ; septis 
in quinqne cgclis dispositis, egelo tUtimo scepissinie imperfecto, sub-jlexuosis, prlmariis 
crassissimis, medio fortissimis, ad termiuationes internas valde attenuatis, sequentibus 
gradatim in magnitudine decrescentibus, lateraliter minutissime denticulatis ; spatio 
columellari centrali hand elongato, parvo. 
A large sub-cylindrical or obversely conoid species with an abruptly contracted 
and somewhat twisted, shortly pedicellate base ; the epitheca is very strongly, but 
irregularly developed, the corallum being at intervals more or less contracted, and 
becoming in places quite irregularly rugose ; the calyx is round, slightly exsert, 
apparently with rounded or obtuse edges and an impressed centre. The septa are 
very strong, in five cycles, the fifth cycle is, however, mostly incomplete ; all the 
septa are somewhat flexuous, attenuated at their inner ends, the primaries being 
greatly thickened about the middle; the following septa gradually decrease in 
strength ; their sides appear smooth to the naked eye, but with the lens a very fine 
crenulation or denticulatiou is traceable on most of them. 
The strength of the septa, between which the dissepiments and the endotheca 
are very much developed, and the roundness of the stem, readily sejiarate the pre- 
sent species from the two others knomi from cretaceous deposits. 
Locality. — North-west of Moraviatoor, in a brownish limestone.
