and Mudstone Bay ; Prof. Phillips has met with the same species at Babbacombe, and Prof. 

 M'Coy at Newton Bushel. It exists also in Spain at Millar, in the province of Leon ; 

 in Germany in the Eifel Mountains; and in North America at Corn Island, Falls of 

 the Ohio. 



This species differs from C. lamellosum^ by its cylindroid form and its large transverse 

 wrinkles. C. cylindricmn' and C. Siluriense^ are both easily distinguished from it by the 

 existence of radiciform processes ; and in C. Grai/i* the vesicles are much more oblique 

 towards the surface of the coral, and very irregular towards its centre.
