COSCINAU-EA conf. MAMMILLATA, RCUSS. PI. XI, Fig. 10. 
The only figured specimen which appears to he referable to the European 
species is a cast ; the corallum is globose and sessile by a contracted base ; the upper 
surface has some irregular imj)ressions, and there is no trace of an epitheca. The 
calyces are somewhat concave, mostly one mm. wide, and directly connected by the 
serrated septal costm ; there are about 20 to 21 septa, of which, however, generally 
only eight reach to the centre, occupied by a thin columella. The figure represents 
a portion of the surface enlarged seven diameters. 
I do not see any essential diffei’ence between the Indian and the Gosau fossil, 
but as the former is merely a cast, the determination is somewhat doubtful. 
Locality . — Odium, in a brown limestone. 
Formation. — Ootatoor groiip. 
MADREPORARIA TABULATA. 
(See p. 5). 
Of the four (or perhaps three) families, distinguished in this sub-order 
by the authors of the Hist. Nat. des Oorall. (vol. iii, p. 224), only that of the 
Family, — MILLFF 
is represented by a single species. The family is characterised by a large develop- 
ment of a cellular or tubular coenenchyma. 
XXVI. Genus. — HELIOPORA, Blainville, 1834. 
Massive coralla of a shortly csespitose, tuberose, or lobate shape, with largely 
developed, thinly tubular coenenchyma, forming terminally fine pores on the 
surface, separated by somewhat raised papillose granules ; calyces round ; septa 
very short, but distinct ; no columella. 
Tbe genus merely differs by its very short septa from Folytremacis, in which 
they reach to near the centre ; it occurs both recent and fossil, but appears to be 
one of the rarest corals. M.-Edwards and Haime referred to it two species, 
JR. P«r/sc/u and mac?’os/om«, described as by Prof. Reuss from the 
Gosau deposits. Since then only very few species have been noticed from the 
kainozoic epoch. A single species occurs in the Cenomanien beds of South India.
