This species has been established by the study of a polished slab belonging to the 
collection of Dr. Battersby, and showing a transverse section made at a small distance 
below the calice. The quadrifascicular mode of arrangement of the septa is very distinct. 
The principal septa are forty-eight in number, somewhat thick, and extending to the 
centre of the coral; they alternate with an equal number of smaller ones which are also 
thinner ; towards the middle of each group they are slightly flexuous, and towards the 
outer part they become shorter and somewhat oblique. Some dissepiments are also visible. 
Diameter about eight lines. 
Found at Torquay. 
This species differs from Metriophyllum Bouchardi’ by its septee beg twice as 
numerous and slightly thickened near the centre.
