CEETACEOUS CORALS OR xVNTIIOZOA 
Latimmandm, iu wliicli tlic series of caRces are separated by united ridges, over 
vbicli the costae pass without interruption. These two sections arc so intimately 
connected with each other that authorities on the subject, like Milne-Edwards 
or Rcuss, do not consider a separation into two genera practicable. 
I have to notice five sj^ccies of the genus from South India, only one of which 
is identical with a European form. This and a new species belong to the second 
section which I }nentioned, Avhile three others arc referable to the first. 
The LatiiiKJcandra: occur in all formations, but chiefly in the mesozoic.

The corallum of this species far more resembles that of an Isastrea than of a 
LatimcBandra, being shortly, broadly conical, and covered by a thin, radiately 
costulated theca ; tlie upper surface is flattened or slightly convex. The calyces 
arc, however, separated by distinct, though narrow farrows, and among a number 
of isolated ones there are sometimes two or throe united ; they are rather shallow 
or polygonal. The septa are thick at their outer ends, thin interiorly, granular, and 
laterally provided with moderately numerous spinose subequal tubercles. The 
columella is in some calyces apparently quite absent, in others there are traces 
of it. 
Localities. — East of Parally, in a coarse calcareous sandstone ; north-east of 
Moraviatoor, in an earthy, brown limestone ; rare. 
Formation . — Ootatoor group.
