above and laterally ; there are from IS to Go of tlieai in adult individuums ; those 
of the first and second cycle are equal and extend to the spongiose colum ella ; those 
of the third cycle are slightly shorter, while the subsequent generally decrease in 
length, and sometimes connected with each other or with the preceding septa. 
Lomlitij . — North of Aluudanapooram, in a coarse conglomeratic sandstone ; 
common. 
Formation . — Trichinopoly group. 
In Europe the species has been found in the coral deposits of the Nefgraben 
in the Gosau, which deposits, according to the majority of the fossils they contain, 
appear best to correspond with D’Orbigny’s Turonicn, a geological position exactly 
corresponding with that in which the fossil abundantly occins in South India. 
5. IsASTiiEA conf, IIoRXESi, Bcuss. PI. VII, Eig. 9. 
A remarkable species with large (6-7 mm. wide) angular calyces and with from 
48 — 60 very thin, granular, laterally thickly spinulated septa of unequal length, and 
a large spongiose columella. 
There is a fragment and an entire corallum, which had been sessile by a 
somewhat narrowed base, in our collection. The stem is covered with an epitheca, 
which is near a few concentric swellings, and also near the upper edge costulated, 
the ribs being in those places granulai’. The species exhibits, as regards the form of 
calyces and the number of septa, the greatest relation to Isast. Uorncsi, (Ptouss),

the identity of the species. 
Locality. — Moraviatoor, in coarse calcareous sandstone. 
Formation . — Ootatoor group. 
XVIII. LATIALEANDPtA, d'Orhiejny, 1849. 
Alilne-Edwards and Haime, Hist. Nat. des Corall. ii, p. 543. 
Corallum variable in shape, forming globular, subpedunculate, irregularly 
expanded, or even subdendroid masses, the consistency or solidity of which depends 
upon the greater or lesser development of the mural theca, connecting the single 
individuums ; the enlargement of the stem takes place by gemmation at or near 
the edge of the calyces, which arc more or less distinctly separated from, or con- 
fluent with, each other, and are very variable in form ; the columella is rudiment- 
ary ; septa granular above and spinulosely serrated laterally. 
Latimceandra differs from Isastrea principally by the tendency of the calyces to 
become confluent, forming united series. There can be two sections distinguished. 
The one — called Chorisastrea by Fr omen tel — in winch the calyces arc separated 
from each other by more or less distinct depressions, and the second, or true
