CORALS FROM THE MOUNTAIN LIMESTONE. 159 
Corallum constituting a tall pyriform mass, the upper surface of which is very convex, 
with polygonal calices and simple well-developed walls. The ca/ices are somewhat unequal 
in size and in form, being sometimes rather triangular, tetragonal, or hexagonal. The 
corallites are very long, and radiate from the basis of the corallum to the top. The wails 
are not perforated. Zuéul@ horizontal, and placed at about one sixth of a line distance. 
This fossil has been met with at Hilsington Barrow, near Kendal, and in various 
localities in Russia. The only British specimen which we have seen belongs to the 
Museum of the Geological Society of London, and is not in a state of preservation 
sufficiently good to render it worth being figured in this Monograph. 
C. radians differs from most of the other species belonging to the same genus by its 
massive, convex form, and apparently also by the absence of mamille on its surface. 
The same characters are met with only in C. crixitus' and C. Trigeri,? but the first of 
these corals differs from the species above described by the existence of superposed layers, 
and the second by its large calices and slender walls.

Corallum forming cylindrical branches of various sizes. Calices unequally developed, 
with rather thick margins. In general eight calices occupy the space of about one line, 
but on the slightly projecting gibbosities of the surface of the corallum the calices are 
somewhat larger, and almost circular. 
This fossil has been found at Harrowgate, Greenhow Hill, Brough, Kirby Lonsdale ;
