Formation and Localities. — Mr. James Thomson iound this species in 
tlic shales wliich, in Scotland, form the base of the Carhoniferons Limestom;, 
Avhich I consider analogous to the Vise Limestone. A single specimen was 
found at Burragood, on the Paterson, New South Wales.

Corallum conical, of moderate size, slightly curved, with its external 
surface all hut perfectly smooth in spite of its tliin cpitheca. The calice is 
very deep and circular, with sharp, straight edges. The primary septa, thirty- 
six in number, are thin, and all rcacli the columella, alternating with the 
same number of secondary sej)ta very little developed. The columella is 
central and slightly compressed laterally. The fossula is large and deep, and 
its position corresponds to neither of the two curves of the coral, being some- 
times to the right and sometimes to the left. 
Dimensions. — The length is about three centimetres, and the diameter 
of the calice one and a half centimetres. 
Distinguishing Characteristics. — This species is rather like Lopho- 
phyllum Konincki, Milne Edwards and J. ITaime, hut differs in shape, by 
its smooth surface, by the number of its sej)ta, and above all by the lateral 
position of the fossula. 
Formation and Localities. — Specimens of this species were found at 
Colocolo in a greyish and in a reddish limestone, coloured by oxide of iron. 
Most of them were casts.
