CEETACEOUS CORAES OR ANTIIOZOA 
epitlicca ; the costte, corresponding to the first three cycles, originate almost imme- 
diately above tlie base, hut the granulation becomes gradually stronger towards 
the upper edge of the corallum. In both specimens the four cycles of septa ai’c 
perfect and very regular, but the pali are only slightly prominent and almost 
join the tertial septa. The grannies on tlie costoe are all rounded. In a section 
some distance below the calyx the two adjoining pali appear almost to unite and 
meet with the secondary and tertiary septa. 
Localities. — Xorth-east of Odium ; a single cast specimen in a whitish shell- 
limestone ; east of Kauray, also a single specimen in a sandy limestone. 
Formation . — Ootatoor group. 
4. Caryopiiyllia gracilis, Stoliezka. PI. I, Eig. 18. 
Caryoph. corallum sub-cylindricnm, curdatum, basin versus compressiusculum 
atque basi compressa ramose dilatata ajji.vum, theca murali tenuissima ; superjicie 
omniao costala, costis subcequalibus, rcctis, latiusculis, niodlce elevatis, minutissime 
granulate rugidosis ; calyce fere circulari, paululum excavato ; septis tenuissimis, 
paido undulatis atque lateraliter spinulis acutimculis numerosis instructis, in quatuor 
cyclis perfectis dispositis, palis dnodecim, elongatis, tenuibus, ad terminationes 
septorum ad tertium cyclum perlinentium ac brevium sitis ; columella laniellis tenuis^ 
shnis, torlis et spinulosis composita^ circ. quartam pjarlem calycis dimnetri ceqnante. 
This species is readily recognised from the other sub-cylindrical forms, like 
C. Bredai or C. Bebeyana, by the peculiarly compressed and ramose base, by the 
external surface being entirely costated, by the very thin, spinulose septa, and the 
rather elongated and slightly thickened p)ali. This last character shows that the species 
belong to a group of Caryophyllue, winch Milne-Edwmrds and Haimc separated 
under the name of Bathycyathus, and which Eromcntcl, I think, rightly unites 
with the present genus. 
Locality. — Ootatoor ; a single sjiecimcn occiuTed in a light coloured limestone ; 
the calyx has been so much obliterated by adherent rock that it had to be filed off, 
in order to permit a clear view of the disposition of the septa. 
Formation . — Ootatoor group. 
11. TROClIOCAAVTnUS, Ililne-Fdwards and FLaime, 1848. 
The corallum is oupuliform, or more or less cylindrically elongated and conoid, 
sessile by a dilated or pedunculate base, but genei’ally becoming free in the adult 
stage ; mural theca well developed in the entire length of the corallum, costte 
granular or sometimes spinulose ; calyx moderately concave ; septa in six systems, 
and four to six cycles, above sharp, laterally striated, and granulated ; ivali numerous, 
uncfpial in length ; columella well developed, broad, composed of twisted strings or 
columns, or contorted laminte, granular and generally convex at the upper end.
