CEETACEOUS CORALS OR AXTIIOZOA 
These are arranged in five complete cycles, those of the first cycle being conspicu- 
ously stronger than any of the rest, somewhat thickened at their inner ends ; in the 
two next cycles the septa are equal and only a little shorter than the primaries, 
AA'lule the following orders gradually decrease in size and strength. 
Locality. — East of Parally, in a sandy limestone, a single specimen was found. 
Formation . — Ootatoor group.

Troch. corallnm modice elevatuni, stih-cylindraceum, ad intervalla irregulariter 
contractum, hasi lateraliter ciirvata imulumqiie angiistata ajfixam ; costis siib-distan- 
tibus, aculis, granulatis, fortiorihus atqiie tenuioribiis alternantibus ; seetione 
rotundate elliptica, spatio columellari sub-angusto, circiter tertiam partem diametri 
longioris (cquante ; septis in qnatiior cyclis dispositis, primariis atque secundariis ad 
terminationes internas inorassatis. 
Although of a similar type to the previous species, in being sessile by 
a rather broad base, the shape of the corallum is distinctly elliptical in the present 
form, and the septa are differently arranged, meeting with their ends along a con- 
siderably extended columellar space. The septa themselves are also more irregu- 
larly undulating, and those of the three first orders are sub-equal in length and 
strength, conspicuously thickened at their inner ends. 
Locality. — East of Parally, in a sandy limestone, only two specimens w^ere 
found. 
Formation. — Ootatoor group. 
A third specimen was found a little more south from the above-named locality, 
north of IMoraviatoor. It is a very imperfect one, (Comp. fig. 23, on pi. I) ; 
the corallum is very short and rapidly increased in diameter ; the base appe'ars to 
have been very broad, but, like the upper part, it was not perfect, and both have been 
filed off in order to show the disposition of the septa. The lower section is nearly 
circular, showing, however, a somewhat irregular increase of corallum ; originally 
it had only four complete cycles of septa very similar in form and distribution to 
those of T. camura. The upper section is roundly ovate, and shows five complete 
and a sixth incomplete cycle of septa, those of the three first cycles all ending at 
the edge of the columellar space with a slightly thickened knob. The costa3 arc 
apparently alternately thicker and thinner, but are on no part of the theca well 
]n’eservcd. Judging from the majority of the characters alluded to, I much rather 
suspect that the present fragmentary specimen represents a large and somewhat 
straight growing corallum of T. camura than that it belongs to a distinct 
species. When better specimens have been found, it will have to be ascertained by 
observation whether the apparently cuneiform shape of the specimen is sufficiently 
constant to necessitate a separate designation from the one above noticed.
