CORALS FROM THE DEVONIAN FORMATION. 243 
Corallum composite, forming almost flat masses. Calices slightly prominent and 
placed at unequal distances (in general about 13 their diameter). Coste irregularly con- 
fluent, large, rather thin, equally developed, flexuous or geniculated, delicately crenulated, 
and closely set (about a quarter of a line apart); 15 or 16 principal ones slightly exsert, 
termmated by an arched edge, extending almost to the centre of the visceral chamber, 
where they become very slender, bearing a small paliform lobe and alternating with an 
equal number of small septa; wa// well developed, rather thick. Co/wmella appearing to 
be slightly compressed. Diameter of the calices 14 line ; depth almost half a line. 
Found at Torquay ; and at Valcos in the province of Leon in Spain. 
In the Collection of the Geological Society of London, &c. 
This species differs from S. organum* and 8. Torreanum’ by the costal radii being more 
numerous and more confluent.

Corallum simple, very long, slightly bent, subcylindrical, provided with a very strong 
epitheca, and presenting rather strong subhorizontal circular wrinkles. Calicular cavity 
rather deep; the septal strize, when visible, more distinct towards the outer part of the 
calice. Vesicules unequal in size; the largest occupying the centre of the visceral cavity 
and about 1 line in length. Height of the coralin general about 3 or 4 inches. We have 
seen in the collection of Mr. Pengelly a specimen that measured above 1 foot in length, 
-and 13 inch in diameter. 
The British specimens submitted to our examination were found at Torquay, Plymouth,
