CORAL FAUNA OF HALDON, DEVONSHIRE. 91 
projecting close to the calicular margin, and are formed by simple 
series of granulations. ‘The calice is elliptical in outline, the axes 
being as 1:14. There are four or five cycles of septa, and the 
septa are unequal and stout. ‘The species is from the Gosau Creta- 
ceous series of the age of the French Craie tuffeau.

The corallum is massive; the corallites are united by their walls ; 
the calices are circular in outline, and there is no columella. Pali 
exist before the primary septa. The coste are well developed, and 
do not unite with those of other calices, or pass from one calice to 
another. ‘The endotheca is abundant, and closes the calice inferiorly 
as if by false tabule. 
Hatponta Vicaryi, sp. nov. (Pl. VIII. figs. 2, 3.) 
The corallum is massive, with a broad inecrusting base and a 
slightly convex surface. The calices are separated by a slight de- 
pression, are rather raised, deep, and widely open. ‘The coste are 
well developed, slightly erect, larger than the septa, long, straight, 
broad, separate, widest without and rounded above; those of the 
first and second cycles are the largest, the primaries exceeding the 
secondaries. The septa are slender, but well developed, long ver- 
tically, and not exsert; they are unequal, and form three cycles in 
six systems; the primaries are the longest, and reach furthest 
towards the axial space. ‘The pali are small, distinct, and narrow, 
but they are largely granular and broadly ridged, and are placed 
just within the primaries. The breadth of the calices is =}; inch.

The corallum incrusts shells or littoral concrete; it is flat, slightly 
uneven, gibbous, and depressed here and there, and covers much 
space. The valleys are short, straight, often radiating, sinuous, 
or shorter and gyrose; they are very narrow, but are deep and 
without columella, and are closed at some depth by an endotheca 
resembling tabule, which do not, however, quite reach across. 
The collines are very narrow, sharp; and the septa join above on a 
wavy ridge; they reach but a small distance from the colline, but 
are long vertically, and are subequal and placed at regular intervals, 
and are crowded and stout. The endotheca is situated deeply, and 
extends more or less across the valley. Width of a valley and two 
collines from J, to >}; inch.
