Corallum generally forming clicliotome, round or somewhat compressed branches, 
on wdiich the calyces are irregularly and rather densely distributed. They arc round 
or roundly polygonal, on a well preserved surface with somewhat raised margins, 
which arc crcnulated by the costec passing over the same. When the surface is not 
well preserved, the calicular margins become obliterate by the costoe, and appear 
more depressed than the intcrspaecs. The width of the calyces varies from I'o to 
2 mm., and they are one to one and a half mm. distant from each other. There arc 
three complete cycles of thin septa, all finely serrated on the upper edges, and 
laterally densely spinulosc ; those of the first and second cycle arc equal in strength 
and length, extending to the very massive and solid columella ; those of the third 
cycle are much shorter and tliinncr. On a section the costo- mural theca is rather 
coarsely and irregularly granular. (See fig. 4i). 
Locality. — Moraviatoor, in a brownish limestone ; not uncommon. 
Formation. — Ootatoor group.

In general character the present species resembles an Astrocoenia, hut the 
calyces are well defined, rounded, their edges crenulated by the very short costae. 
There are, as a rule, only two cycles of septa developed ; very rarely are a few very 
short ones of a third cycle noticeable. Scarcely any of the calyces exceed I'o mm. 
in width. I have not been able to see whether the upper edge of the septa is 
crenulated ; laterally there arc only few very minute denticles to he observed. 
Locality. — Ninnyoor, in whitish limestone; only three specimens, the larger 
of wdiich is 75 mm. long and 50 mm. broad, have been found, 
Forma t ion . — Arrialoor group.
