CORALS FROM THE DEVONIAN FORMATION. 221 
almost right angles. A vertical section shows that the corallites diverge from the centre 
towards the surface of the branches in an oblique ascendant direction, are somewhat 
flexuous, and terminate by a calicular margin that is prominent at its under part. The 
walls are thick. In some places the faéu/e@ appear closely set, but in most parts of the 
specimen submitted to our investigation they were completely destroyed. The indications 
of the mural pores were also obscure. Diameter of the branches about 14 line, that of the 
calices about 1th of a line. 
This Coral was found at Torquay by Dr. Battersby, and is known to us only by a 
polished specimen belonging to the collection of that paleontologist. We at first thought 
that it might be referred to the Ceriopora Goldfussi of Michelin, but Professor M‘Coy, 
who appears to have had some better preserved specimens, has “since that recognized the 
existence of triangular calices and a fissiparous mode of multiplication. He therefore 
places this fossil in the genus Alveolites, and after more ample investigation we have been 
led to adopt his opinion. Professor M‘Coy adds that <Alveolites Vermicularis is poly- 
morphous and is met with at Teignmouth, at Newquay, and at Bedruthen Steps, 
St. Eual.

Corallum massive. Calices arranged in a circular manner round divers places on the 
surface of the corallum, compressed, elongated, and very unequal in size, the larger ones 
bemg about half a line across. Jails thick exteriorly, and convex. The three septal 
processes somewhat unequally developed ; short, but quite distinct. 
This species resembles Alveolites orbicularis' by its general appearance, but differs 
from it by the calices being much more unequal in size, arranged in circular lines, and 
provided with three septal processes that do not differ in size. 
Found at Torquay by Mr. Pengelly. 
Family PORITID&, (p. lv.) 
The singular fossil coral to which Goldfuss gave the name of Pleurodictyum pro- 
blematicum™ has been met with in the Meadsfoot Sands near Torquay, by Prof. Phillips;’ 
but we have not as yet seen any British specimen of that species, and we must therefore 
refrain from describing it here. We hope to be able to have it figured in an appendix to 
our Monograph.
