CllETACEOUS CILIOPOEA 
XIII. Genus. — IIETEEOPOIIA, Blaiiiv., 1831, (see p. 27). 
1. IIeteropora Tamulica, StoUezka, PI. Ill, Eig. 4. 
II. colonia ramosa, ramis dichotomis, cylindraceis ; cellulanim apertnris sub- 
tubulosis, plus minusce in'eyulariler .'tpco'sis, ostioUs n umerosisslmis, nonnull'is paululum 
elongatls atque in seriehus indisUnclis longltudinuliler undulatis dispositis. 
Erauclies dicliotoin and cjdiudrical, -with the orifices of the cells round, 
moderately projecting above the surface of the stem, and with very numerous in- 
terspersed small pores, many of whieli are slightly elongate and connected into 
more or less distinct, longitudinally undulating, series. On some portion of the 
branches the apertures of the cells have sometimes a disposition to arrange 
themselves in transverse scries, hut in other places there is no regularity to he 
observed in tlic arrangement. In the centre of the stem, the colls are, as usually, 
irregularly arranged, curving outwards to each side, and as they are much more 
delicate in the centre than round the surface, they are easily broken in at the termi- 
nations of the stems, which then have the appearance of d’Orhigny’s Semicrescis 
or Ilagenow’s Cavaria. The species belongs to the same tjqie as Hagenow’s 
II. Dumonti (Bryoz. Maast. Kreide., p. 48), differing from it by the apertures heins 
closer together, and also a little larger, as are likewise the intermediate pores. 
Localily. — Yermanoor, in j^ellowish soft sandstone. 
Formation . — Ai'rialoor group. 
XIV. Genus. — ZOXOPOBA, d'Orb., 1849, (seep. 27). 
1. ZoNOPORA INDICA, StoUezka, PI. Ill, Eig. 5. 
Zon. colonia ramulis crassis, ad intervalla brevia contraetis atque in tdroque 
latere obtuse tuberosis, in partibus elevatis orificiis majoribus atque minoribus, 
rotundatis, dense intermixtis instructis. 
A single fragment of this form differs from the several allied species described 
by d’Orhigny by the obtuse protuberances being conspicuously more developed in 
two opposite directions, so as to give the branch a slightly compressed appearance 
and a broadly elliptical section. The protuberances are larger and more widely 
separated than in Zon. undulata, which in other respects the Indian species closely 
resembles. The orifices are, strictly speaking, of three kinds: those in the contracted 
portions are of medium size, all equal or suhequal, and separated from each other l)y 
interspaces, Avhich are as broad as the diameter of each orifice. On the elevat(Hl 
portions the large round orifices are sepai’ated by smaller ones, which, again, differ 
in size, some of them equalling those in the depressions and others arc still smaller. 
The cells in the centre of the stem are vertical, and those adjoining them 
gradually bent out towards the margins. 
Locality . — North of Poodoopolliam, in a whitish limestone. 
Formation . — Arrialoor group.
