Corallum simple, tall, almost straight, pyramidal, and quadrangular. Epitheca 

 presenting strong accretion folds. Calice almost square, rather deep, and appearing to 

 contain about 50 septa. The septal fossulae are not distinct in the only specimen that we 

 have seen. Height about 1 inch.

We refer to this species an apparently ill-preserved specimen found by Professor 

 M'Coy in the Silurian deposits of Ireland, and placed by that palaeontologist in the non- 

 characterised genus Petraia. 



In well-preserved specimens, such as those that are found in Gothland, and have been 

 figured by Hisinger, and described by us in a former work, the following characters are 

 seen : Corallum simple, pyramidal, slightly curved, with a very narrow peduncle ; rather 

 thick epitheca and accretion ridges that sometimes constitute at the angles irregular 

 tubercles, and even thus assume the appearance of short radiciform appendices. Calice 

 almost square, not very deep. Septal fossulse pretty well characterised, and corresponding 

 to the angles of the visceral chamber. Septa (72) rather thick, but very slightly prominent, 

 and extending almost to the centre of the calice, where they are slightly fiexuous. Height 

 about 1 inch. 



Ardaun and Kilbride, Cong, in the county of Galway (M'Coy). Gothland. 



G, Fletcheri x differs from this species by its narrow elongated form, and by its septa 

 being less numerous, and by several other characters.
