220 BRITISH FOSSIL CORALS. 
terminated by an irregular or subgibbose surface. Cualices very oblique, closely set (but 
unequally so), elongated transversely, subtriangular, and turned towards the edge of the 
corallum. The outer or under side of these calices bears interiorly a small elongated 
ridge, which appears to represent a septum, and is placed opposite to a small notch. 
Transverse diameter of the calices about two fifths of a line; small diameter about half 
that length. 
Found in the Devonian deposits of Torquay, Tor Abbey, Babbacombe, Teignmouth, 
and, according to M. Phillips, at Hope. 
Specimens are in the collections of the Geological Society, Messrs. Battersby and 
Pengelly at ‘Torquay. 
Alveolites Labechei' is a massive subgibbose species, very nearly allied to the above- 
described coral, but differs from it by the interior dentation of the calicular edge being 
but slightly developed, and by the calices being more irregular in size. In 4. Battersby? 
the septum represented by this interior expansion is, on the contrary, formed by very 
strong spiniform processes, and the mural pores are very large. 
In A. compressa’ the calices are much more irregular, and the inner processes are 
very small. 
The other species of this genus are not massive.

Corallum forming a subspherical mass. Cadices unequal in size, and somewhat 
irregular. Vertical and horizontal sections show that the wa//s are thin, and perforated 
by large circular pores rather closely set, and that in different places they give rise to 
strong ascending spiniform processes, which, by their superposition, represent unpaired 
septa. Zabule very thin and irregular. 
Found at Torquay. Specimens are in the collections of Dr. Battersby and of 
Mr. Pengelly. 
This species is remarkable for the slight obliquity of its calices, the large size of its 
mural pores, and more especially for the great development of its septal processes.
