and Tcry nearly equal this in size ; tiiey arc slightly convex, and occasionally with 
a small slit situated above the upper lij) of the aperture ; they are entirely separated 
from the next following cells, not resting on their bases, as is very often the case 
in similar forms. 
Locality . — Chokonadapooram, sessile on the shells of Bxogyra ostracina, Lam. 
Formation. — Arrialoor group.

The cells arc depressed, sub-ovate, or sub-bcxagonal, provided with more or 
less distiiict, sub-marginal superficial ridges, Avhich, however, occasionally become 
quite obsolete. The surface is very finely punctated, or often a])parcntly quite 
smooth, slightly elevated, particularly towards the aperture, which is scmielliptical, 
nearly quite anterior, and almost borizontally placed; it is surrounded by a 
tluckened margin, the lower lip being straight and having a minute incision at 
each end. The slitters are interspersed l)etwecn the other cells ; they are much 
smaller than these, depressed, somewhat diamond shaped, anteriorly much attenuat- 
ed and produced into a point, with an elongated slit-like aperture. No avicularia 
or ovicclls have been observed 
This species is closely allied to d’Orbigny’s C. xipliia (Pal. Franc. Terr. Cret., 
v, p. 413, pi. 717, figs. 3 and 4), the latter ditfering from the Indian form by a more 
elongated shape of the cells, and by the occasional development of what appear 
to be true avicularian 2 iores. 
Locality. — North of Poodoo 2 )olliam, on Terebratula sub-dejmessa, StoL, form- 
ing widely spread colonies. 
Form at io n . — Arrialoor groiqi .
