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 fossule 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 palzontologist 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 fossulee 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 flexuous. Height 
about | inch.

G. Hetcheri differs from this species by its narrow elongated form, and by its septa 
being less numerous, and by several other characters.
