dispositls, nonnunqtiam chiohis vel irihiis septis ad cijchmi qiiarkim perthientilms

mdlata. 
This species foi-ras large convex or nodular masses, some of them averaging 
one foot in diameter, and they are nearly quite as high. The calyces are generally 
polygonal, mostly hexagonal, and the united raised margins are ornamented with a 
single row of well marked tuhcrclcs. The septa arc arranged in three complete 
cycles and six systems ; sometimes there arc two or three septa of the fourth cycle 
developed in one of the systems ; all are provided with somewhat flattened granules 
on their upper edges; the columella is of moderate size, forming a conspicuous 
hemispherical knob in the centre of each calyx. 
In general character this species resembles Ast. Konincld, fA. onagnifioa, apud 
Reuss), but it differs from it by the number of septa. There is, I think, as yet no 
cretaceous species known with thi-ce com[)lctc cycles of septa regularly arranged in 
six systems. 
Localities. — Ootatoor, east of Kauray, north-west and north-east of Horaviatoor ; 
common in brownish or whitish limestone. 
Formalion . — Ootatoor group.

Astroc. corallum semi-glohosum, aid late planeque expansum, crassum ; calycihus 
1-2 ad 1'75 frare 1) mm. latis, polygonis, modice distantibus, margine quoque spinu- 
lose tuhercidifero ; septis in duobus cyclis dispositis, primariis usque ad columetlam 
solidam crassiusculam extensis, secundariis paido brevioribus, rariter septis nonnullis 
brevissimis ad cyclum tertium pertinentihus observandis. 
This species is somewhat allied to A. Tourtiensis, Bolschc (inOcinitz’s ‘Elbe- 
thalgebirge in Sachsen,’ part i, 1871, p. 54), differing from it by more distant calyces, 
which have very distinctly and spinulously tuberculated margins. There are, as a 
rule, only two cycles of septa, those of the second cycle being conspicuously shorter 
than those of the first, while in the European species the two are of equal length. 
Sometimes there are some very short septa of a third cycle developed in the larger 
calyces. The coralla are very massive, either semi-globose, or with a flattened 
upper surface. One of the largest specimens is 110 mm. long, 60 broad, and 
equally high. 
Localities. — Odium, IHoraviatoor, and east of Kamay ; mostly in a bromiish or 
pinkish limestone. 
Formation . — Ootatoor group.
