CORALS FROM THE DEVONIAN FORMATION. 225 



the centre of the visceral chamber, where they become shghtly curved. Height 2 inches ; 

 diameter somewhat more than 1 inch ; depth about 8 Hues. 



The specimen found at Torquay belongs to Dr. Battersby. This species is also met 

 with at Bensberg and in the Eifel Mountains in Germany. 



The type specimen of this species is from the Eifel Mountains, and has only 74 septa. 

 The Torquay fossil that we consider as belonging to the same species, and have 

 figured here, present more than 100 septa; but that difference evidently depends on an 

 accidental multiplication of these laminse in one part of the septal system where they are 

 more closely set than elsewhere. The species most nearly allied to C. Boemeri is 

 C. Michelini} but the latter is adherent, its septal fossula is rudimentary, and its septa 

 less closely set.

Corallum simple, elongated, subcylindrical. Calice circular. Principal septa (32 or 34) 

 very thin towards their inner edge and somewhat thicker exteriorly, much curved and 

 twisted near the centre of the calice, and alternating with an equal number of others that 

 are smaller and still thinner. Vesicular dissepiments well developed on the exterior part 

 of the visceral chamber. Height about 2^ inches ; diameter of the calice, 1 inch. 



Found at Torquay, Plymouth, and Newton Bushel, by Mr. Lonsdale ; and at Dar- 

 lington by Mr. Philhps.

This species is very remarkable on account of the septa being so strongly twisted near 

 the centre of the visceral chamber, — a character which distinguishes it easily from 

 C. Michelini^ and C. Boemeri^ that in other respects resemble it very much.
