CORALS FROM THE MOUNTAIN LIMESTONE. 167 
end and forming four cycla; those of the first three cycia nearly equal, alternating with 
an equal number of smaller ones, and extending in general to the columella, where they 
present a small obtuse lobe; the tertiary ones are inclined towards those of the second 
cyclum, and become united to them near the centre of the visceral chamber. Height of 
the coral from 5 to 8 lines; diameter of the calice 2 lines. A vertical section shows that 
the interseptal loculi are quite open. 
This fossil has been found at Kendal and at Tournay. A very ill-preserved coral, met 
with in some part of Yorkshire, also appears to belong to this species. Professor M‘Coy 
mentions its existence in Derbyshire. The only well-preserved British specimens that we 
have seen belong to the collections of the Cambridge Museum; specimens from Belgium 
are common in the paleontological collections in Paris. 
In our Monograph of the Corals from the Paleeozoic Formations we have described five 
other species of Cyathaxonia, which can all be easily distinguished from C. cornu : 
C. Konincki' by being fixed ; C. cynodon” by its walls being armed with rows of spines ; 
C. tortuosa’ and C. profunda‘ by their septa being more numerous, and by their greater 
size; and C. Dalmani’? by its thick form and its strongly compressed subcristiform 
columella.

CyarTuopsis cornucoPie ? M‘Coy, Brit. Paleeoz. Foss., p. 90, 1851. 
Corallum conical, elongated, curved, delicately pedunculated and bearing very slight 
circular wrinkles. Calice oval and deep. Septal fossula centro-dorsal, elongated. Septa 
numerous ; thirty-two large ones alternating with an equal number of thinner but well- 
developed ones; the former are rather thick at their upper end, but very narrow, and 
extend to the edge of the septal fossula, on the side of which they are slightly curved, and 
become united together. Height of the coral one inch, or somewhat more ; great diameter 
of the calice at least 5 lines ; its depth 4 or 5 lines.
