168 BRITISH FOSSIL CORALS. 
Professor M‘Coy mentioned the existence of this species at Red Castle, Maset Rath, 
Glasgow, the Isle of Man, and Kendal. Specimens from Tournay are in the Paris 
Museum, and in the collections of M. de Verneuil and M. Michelin. It is from the latter 
that we have described this fossil, and it is only on the authority of Professor M‘Coy that 
we enter it here in the list of the British Corals. 
Z. cornucopi@ is easily distinguished from most species belonging to the same genus 
by the position and the form of the septal fossula, which extends from the centre of the 
calice to a small distance from the mural margin towards the large curve or dorsal side of 
the corallum. ‘This species is, however, very nearly allied to Z. Koninchi,’ from which it 
differs principally by its calice being circular and its septa thicker and broader. In 
Z. centralis’ the septal fossula is also placed in the centre of the calice, but does not extend 
outwards, and the septa are strong, and seem inclined to form four groups. Z. Grifithi 
is much stouter, and its calice presents two small lateral septal fossulee. In Z. Ennishillent* 
the septal fossula extends from the centre of the visceral chamber towards the concave side 
or small curve of the wall. In Z. Bowerbanki’ the fossula remains limited to the centre of 
the calice, and in Z. PAillipsi® it is almost central and circular.

ZAPHRENTIS Puiuiipesit, Milne Edwards and Jules Haime, Pol. Foss. des Terr. Palzeoz., 
p. 332, pl. v, fig. 1, 1851. 
Corallum shghtly curved, somewhat elongate, and encircled with a few well-marked 
constrictions, sometimes presenting even a series of solutions of continuity in its wall. 
Epitheca strong. Calice circular, very deep, and having a thin margin. Septal fossula 
large, situated towards the dorsal side or large curve of the corallum, but near the centre of 
the calice, deep, enlarged outwardly, and presenting in its middle a septum that is very 
distinct from the other ones. In the adult specimens thirty-two principal sepéa thin, very 
narrow, extending to the edge of the fossula, alternating with an equal number of small 
ones, and forming four groups in consequence of the three primary ones being slightly 
prominent, and representing, with the fossula, a four-branched cross ; in each of the two of 
these divisions situated on the dorsal side of the calice there are seven principal septa, and 
in the two others eight; the first of these septa somewhat deviating from the regular 
radial arrangement. Height of the corallum about 14 lines; diameter and depth of the 
calice 7 or 8 lines. 
Found at Frome, and Slab-house, in England; at Tournay, in Belgium; and at Sable, 
in France.
