p. 382, 1851. 
Corallum composite, astreiform; gemmation calicular and extracalicular. Calices 
polygonal, varying much in size, rather deep, and circumscribed by wa//s that are not very 
prominent, but quite distinct ; thin, and always simple. Forty-six septa, alternately large 
and small, the twenty-three latter not extending far from the wall; the large ones thin, 
terminated by a denticulate edge, which is horizontal near the margin, but very strongly 
arched upwards and inwards, and presenting near the centre of the visceral chamber 
a small paliform lobe; these lobes form a very distinct crown round the centre of the 
calice. Height of the corallum about 25 inches, depth about 2 lines, and diameter of the 
circle of paliform lobes somewhat more than 1 line. 
Found at Torquay; at Montignies, St. Christophe, and Chimay in Belgium; at 
Bensberg, Refrath, and Grund in Germany. 
British specimen in Dr. Battersby’s collection. 
This species differs from C. guadrigeminum' by its calices being larger and shallower, 
and by the paliform lobes of the septa; it differs from C. cespitosum® by these lobes 
being larger than in the latter and the septa more equally developed. In C. doloniense* 
the calices are larger, the septa less promiment and more developed, and the paliform lobes 
are quite rudimentary. In C. marmini* the calices are deep and the septa rather unequal. 
In C. Sedgwick? the septa are less numerous than in the above-described species, and 
become thicker towards three fourths of their breadth.
