CORALS FROM THE DEVONIAN FORMATION. 231 
advance a little more, and present a very small paliform lobe, which is in general rather 
indistinct. All the septa are broad, and their upper edge is somewhat oblique till at some 
distance from the wall, but becomes slightly 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 Cythophyllum 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. Sedgwicki,’ which differs from it 
principally by the septa becoming thicker at a small distance from the centre of the calice. 
C. Davidsoni* presents also the same aspect, but has the calices much smaller, and the 
septa smaller and less numerous.

Corallum composite, subfasciculate 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 calicular 
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 23. 
Found at Teignmouth and Torquay. (Collection of Dr. Battersby.) 
This species differs from C. c@spitosum* 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. guadrigeminum’ by the septa being less regular and the existence of paliform 
lobes, which are absent in the latter species.
