Corallum very tall, forming a loose convex mass, composed of large vertical plates, that 
are themselves made up with single series of tubular corallites united laterally. These 
plates meet so as to form various angles, and to constitute, at the surface of the mass, large 
irregular reticulations; the divisions of which are much larger in one direction than in 
the other. The sides of the reticulations are composed of a series of corallites, varying in 
number from three to eight. Cadices elliptical, and of the same size in the same specimen, 
but varying very much in different specimens (their great diameter varying from almost 
half a line to above 13 line). Walls strong, and covered with a thick epitheca, Septa 
trabicular (12), reaching almost to the centre of the visceral chamber. Tabule well 
developed, horizontal, and closely set. 
Llandeilo flags: Robeston Walshen, Pembrokeshire. Sholeshook, Pembrokeshire 
(Murchison). 
Caradoc sandstone: Hughlev, Salop, Lickey (Murchison).
