OF SOUTHERN INDIA.

VII. PSAMMOSMILIA, Fromentel, 18G3. 
Pal. Fran 9 . ten’, cret., vol. viiij p. 2S8. 
Corallum sub-cylindrical, attached by a broad base and with a rounded shallow 
calyx ; mural theca finely granulated or nearly smooth, formed by super-imposed 
layers, nnthout any costae ; septa in six systems, laterally granular or striated ; no 
columella. 
The genus differs from Coelosmilia and other allied forms by the entire absence 
of costae. There is as yet only a single species known, Fs. Orhignyi, From., from 
the Cenomanicn beds of the island of Aix. 
PSAMMOSMILIA OUIEXTALIS, StoUczlcCl. PI. II, FigS. 10 & 11. 
Psamm. corallum plus mimisve elongate suh-cylindraceum, hasi lata sessile, 
modice arcuatum, superjicie concentrice irregulariter paulo constrictum, suh-lmviga- 
tum, calycem versus gradatim dilatatum ; calyce suh-rotundato, concavo, margine 
tenui ae simpUci instrueto ; septis in quatuor cyclis dispositis, lateraliter granulato 
striatis, primariis crassissimis sed incequalihus, its ad cycluni qitarlum pertinentibits 
minimis, nonnunquam fere ohsoletis. 
Although the two, as yet known specimens of this interesting species, are only 
partially weathered out of a solid limestone rock, both the generic and specific 
characters are quite sufficient to distinguish the Indian fossil from the European 
one. There is not a trace of costae present, and the mural theca appears to have 
been almost smooth, or only very finely granulated. The edge of the calyx is thin, 
entire, and the septa not so prominent, as in P. Orhignyi ; those of the fourth 
are sometimes partially imperfectly developed, which appears to be due to a slight 
irregularity in the growth of the calyx. 
Locality . — South of Cooticaud, in a whitish limestone. 
Formation . — Ootatoor group, (Cenomanien). 
Family,— STYLINIDJE. 
Compound massive coralla, in which the multiplication of the corallites is basal 
or extra-calicinal, and the calyces are entirely free, connected with each other by a 
costal murail ; dissepiments are abundant ; the septa entu-e on the upper edge. 
This group corresponds to the stylinacem of M. -Edwards and Haime, by 
whom it is regarded as a sub-dmsion of the Eusmux^, which again are considered 
as a sub-family of the Astreid/e in the old sense. The above noticed characters 
easily separate the Sttiixwm from other allied families, such as the Astreieye (sensti 
stricto), which have the edges of the septa granular or dentate. 
The South Indian cretaceous deposits have yielded only two genera belonging 
to the present family, Stylina with three, and PJnjllocoenia with a single species ; 
all four are new to science.
