CORALS FROM THE DEVONIAN FORMATION. 231 



advance a little more, and present a very small paliform lobe, M^hich is in general rather 

 indistinct. All the septa are broad, and their upper edge is somewhat obhque till at some 

 distance from the wall, but becomes shghtly convex further inwards. Diagonal of the 

 large calices about 8 lines. 



Found at Ogwell, Torquay ; and at Ferques near Boulogne. 



In the collection of Dr. Battersby, &c. 



This species is very closely allied to Cythophjllum hexagonum,^ but its septa are more 

 similar in size, less prominent at a small distance from the walls, and have much smaller 

 paliform lobes. It bears also great resemblance to C. Sedgwickif which differs from it 

 principally by the septa becoming thicker at a small distance from the centre of the cahce. 

 C. Davidsoni^ presents also the same aspect, but has the calices much smaller, and the 

 septa smaller and less numerous.

Corallum composite, sub fasciculate or astreiform ; gemmation almost always lateral. 

 Corallites very unequal in size, circular when free laterally, polygonal when aggregated. 

 Calice deep and broad. About 40 septa, more or less similar among themselves, thin, 

 delicately denticulated, and extending for the most part to the bottom of the caKcular 

 cavity, where they present only rudimentary paliform lobes ; at a short distance from the 

 wall they are somewhat prominent, and assume there the appearance of an interior wall. 

 Dissepiments numerous. Diameter of the calices 4 or 5 lines ; depth about 2^. 

 Found at Teignmouth and Torquay. (Collection of Dr. Battersby.) 

 This species differs from C. ccespitosum^ by its calice being deeper, its septa less 

 unequal, and more especially by its mode of gemmation, which is almost always lateral ; 

 and from C. quadrigeminu))t by the septa being less regular and the existence of paliform 

 lobes, which are absent in the latter species.
