CRETACEOUS CORALS OR AXTIIOZOA 
ono calyx, of wliich 8 or 10 are mucli stronger than the rest ; hut all are rery 
densely granular on their upper edges. In the lengthened calicular valleys about 
15 to 20 septa are counted in a length of 10 mm., hut those of the third cycle 
become almost obsolete. 
Locality. — East of Parally, in a brownish calcareous sandstone. 
Formation. — Ootatoor group.

An irregularly,- mostly in thin layers,- expanded .species, with an undulating 
upper surface. The calyces are small and mostly united in variously twisted, often 
interrupted, and more or less concentrically arranged depressions of three or four 
mm. in width. The ridges which separate them are about equally broad and rather 
sharply angular. The septa are very numerous, three to one mm. distant, and finely 
granular. At irregular distances some of the ridges hccoine occasionally much 
stronger. 
M. -Edwards and Ilaimc (loc. cit.) draw attention to the very close resem- 
hlance of the present species to L. ataciana ; the former only appears to dilfer from 
the latter by the more or less pronounced concentric arrangement of the calicular 
valleys, and especially by thinner septa. 
Both species have probably to be referred to Ilceandrastrea, which belongs 
to the Favid^, a family placed by M. -Ed wards intermediate between the 
LYTBornYLLixM and the astrbixje. 
Locality . — Xorth-east of Odium, in a brownish limestone ; rare. 
Formation . — Ootatoor group, (upper beds). 
Reuss described the species from the Gosau beds near Piesting in Lower 
Austria, and I have collected specimens of the same in the Edelhach-graben of the 
Gosau valley itself. One of the latter proved on comparison perfectly identical 
with the Indian fossil.
