Dimorphastrea patellaris, StoUczka. PL X, Fig. 2. 
Dimorphast. corallum late breviterque conoicleum, epilhecd crassula, suh-lcemgata 
indutum, hasi angustissima pedicellata afjixmn ; superficie supera glaniuscula ; calyce 
magno centrali septis in qualuor cycUs perfeelis dispositis instructor septls ad primiim 
atqne secundum cycluni pertinentihus usque ad columellam extensis ; calycihus mino- 
rihus in seriehus duobus concentricis sid)-marginalihus dispositis, q)lus minusre dis- 
tincter conjluentibus, septls in tribus cyclis dispositis instructis ; septis omninis 
tenuibus, granulatis, lateraliter crasshiscule spinulatis, theca costo-murali fere obso- 
leta ; columella granulose minuteque papillosa. 
The figured specimen is the only one examined. It is ohversely shortly and 
broadly conoid, with a verynan'ow suh-pedicellate base for a place of attachment; the 
epitheca on the lower side is moderately thin, with few concentric swellings and some 
short ribs near the upper edge. The upper side is flattened, with a large calyx in 
the centre and two concentric rows of smaller ones along the periphery. The cen- 
tral caljTC has four complete cycles of septa, and has a diameter of about 7 mm. ; the 
other much smaller calyces generally possess only three cycles, sometimes there are 
a few septa of the fourth noticeable. The costae are well developed, and, like their 
continuations, rather coarsely laterally spinulose, hut the mural theca is almost 
entii-ely wanting. The coliunella consists of numerous thin, somewhat twisted 
columns. 
Locality. — East of Poodoor, in a brownish, sandy limestone ; apjiarcntly very 
rare. 
Formation. — Ootatoor group. 
XXI. Genus. — COMOSERIS, Orbigny, 1849. 
Milne-Eclwards & Haime, Hist. Nat. des Corail., iii, p. 62. 
The coralla arc composite, generally shortly suh-pedunculate and mostly 
irregularly expanded, below covered with an epitheca, above exhibiting numerous 
confluent calyces, with granulated and laterally strongly denticulated septa, and 
a rudimentary columella ; they are separated by angularly elevated confused ridges. 
Until a short time ago Gomoseris was merely known from a few Jurassic 
species. Recently two tertiary species, (C. and were described 
by Prof. A. v. Reuss from Northern Italy. The discovery of a member of the genus 
in the cretaceous deposits of South India is, therefore, particularly interesting, 
because it proves its existence in the time intermediate between the two formations 
alluded to.
