than any of the others, and often somewhat transversely elongated. The cell 
surface is towards the aperture distinctly elevated, and on the margins of the stem 
it assumes a more or less distinctly tubular shape. 
LocalUy. — Ycrinanoor, in yellowish sandy beds. 
’Formation. — Arrialoor group. 
2. Esciiarifoua omninosa, StoUezka, PI. I, Eig. 10. 
Esch. colonia late foUacea atque varie contorta, cellulis conjlnentihus, in super- 
ficie hand distincter sejiaratis, kevigatis, quaque in parte antica apertura stih-semi- 
lunari, panto immersa, infra apertnram tiimore obtuso, antice directo, ad termina- 
fionem plus minusve aperte qmrforato, et prope hasim poris duobus minutis preedita. 
The cells arc in this species confluent on the surface, only slight depressions 
being indicated between some of them. The aperture is roundly semilunar, and is 
somewhat impressed with sloping, not specially defined margins. Relow the aper- 
ture each cell is elevated, the swelling being somewhat conical, with the point 
directed anteriorly and more or less widely perforated. Besides this there is a pair of 
moderately distant minute pores near the slo]nng base of each cell. The surface 
is in other respects smooth, merely possessing the usual microscopic punctuation. 
Locality. — North of Poodoopolliam, in limestone. 
Formation . — Arrialoor group. 
IV. Oenns. — CELLEPORARIA, Lamouroux, 1821. 
This genus merely differs, as already stated, from Cellepora by the manner 
of growth, the cell layers being numerous and generally irregularly superimposed. 
The colonies arc either incrusting other objects, or they form short, blunt, rounded 
and more or less rajuified stems. 
The species of the genus are tolerably numerous in the present seas, and they 
were also abundant in the tertiary epoch, but very fcAV are knoAATi from cretaceous 
rocks. 
Eor this reason only I mention the occurrence of a short, dichotome, blunt 
stem of a species of tins genus in the sandy Arrialoor beds at Chokonadapooram, 
but the cells arc so much worn doAvn and injured that it would be worthless to 
look for any distinctive characters in them. They appear to be slightly convex, 
smooth, elougately ovate, indistinctly separated from each other by narroAv depres- 
sions, with a small anterior semilunar apcrtiu'c and a fenv minute pores interspersed 
between the cells. Until better specimens have been procured the species must 
remain undetermined. Eigures 11 and 11 a on plate I give an illustration of the stem 
of the natural size.
