110 CARBONIFEROUS CORALS AND BRACHIOPODS 
fine vesicular tissue in which septa and outer walls cannot 
be distinctly traced. 
Distance between columella of adjacent corallites varying 
from 5 mm. to 10 mm. 
One of the specimens is marked “ Rownham Point,” 
another “ Leigh Woods.” They are derived from the same 
horizon as the specimens of Liihostrotion Portlocki. 
It is interesting to notice how similar are the horizontal 
sections of this species and of the one last described ; the only 
difference consists in the well marked outer walls shown 
by the first described species. 
Gy athophy Hum. 
Cyathophyllum Murchisoni, Ed. and H. (including 
part of Cyatho'phyllum Stutchhuryi, Ed. and H. 
= Strephodes multilamellatum, McCoy). 
Here I include all the elongate forms usually considered 
to be separable into two species (C. Murchisoni and 
(7. Stutchhuryi) ; but I exclude those short forms, pre- 
viously referred to C. Stutchhuryi, which have a broad 
convex rim with strongly projecting edge ; these are trans- 
ferred to C. regium. (Thus I consider Figs. 3, 3a, 36, 
PL 33, and Figs. 2, 2a, PI. 31 in the Palseontographical 
Monograph to belong to the same species, viz., C. Murchi- 
soni, whilst Fig. la, PI. 31 should, in my opinion, be 
separated and regarded as a simple form of G. regium.) 
Some explanation is undoubtedly called for in making 
so radical a change, and this I give as briefiy as possible. 
The following table gives the distinctive characters 
emphasized by the authors of the two species ; those 
characters printed in italics were added subsequently 
to the definition of the two species, and first appeared 
in the Palseontographical Monograph.
