CORALS FROM THE INFERIOR OOLITE. 125 
CHAPTER XI. 
CORALS FROM THE INFERIOR OOLITE. 
The corals found in the Inferior Oolite of England belong to twenty-seven species, 
seventeen of which have not as yet been met with on the continent. Most of these fossils 
(twenty-one species) belong to the family of Astrezde ; two species belong to the family of 
Turbinolide, and two to the family of Fungide ; one appears to belong to the family of 
Cyathophylide ; we refer it, with some hesitation, to the genus Zaphrentis, and must 
particularly point out its existence here as being the last representative of that important 
family, which was so abundant in the older geological periods, and is almost ex- 
clusively characteristic of the Palaeozoic Formations. Most of the corals here described 
have been seen only in the Inferior Oolite; but three species (Stylina solida, Anabacia 
orbulites, and Comoseris vermicularis) exist also in the Great Oolite. The principal 
localities from which these fossils were obtained, are Dundry, Bath, and Castle Cary in 
Somersetshire, Burton Bradstock in Dorsetshire, Wotton-under-edge and Crickley in 
Gloucestershire.

Corallum simple, discoid ; its under surface flat or slightly concave, presenting a small 
central dimple, and a thick epitheca with circular wrinkles. Ca/ice shallow, slightly 
depressed towards the centre. Co/wmella lamellar, rather thin, free to a considerable 
distance from its upper end, and terminated by an entire edge. Sepéa straight, rather 
thin, very exsert exteriorly as well as upwards, and terminated by an arched, delicately- 
crenulated edge ; they form four complete cycla, and an incomplete fifth cyclum in two or 
four of the systems, very rarely in all; those of the second cyclum almost as large as the
