120 CARBONIFEROUS CORALS AND BRACHIOPODS 
Campophyllum. More material is required to definitely 
settle the relationship. 
The specimen is from the uppermost beds (“marly bed 
behind the Colonnade ”). 
Lonsdaleia. 
Lonsdaleia floriformis, Fleming. 
Several typical specimens, cut and uncut, are in the col- 
lection, derived from the uppermost beds. 
The horizontal sections illustrate that form in which the 
central area shows a characteristic spongy structure, 
which is probably a subsequent result of solution and de- 
position upon the typical cobweb arrangement of radials 
and concen tries. 
Lonsdaleia aff riigosa, McCoy. 
A few poor specimens in which the corallites tend to 
separate and are cylindrical, with strong external swellings, 
may belong to this species, but, until they are sectioned, 
they cannot be definitely named. 
MOIQ-TICULIPOBOID. 
Pistuiipora. 
Fistulipora aff incrustans, Phill. PI. I. Fig. 1. 
The only specimen in the collection is a polished slab, 
labelled Ashton, which exhibits both horizontal and vertical 
sections. 
Horizontal section : — 
Autopores almost or quite circular, with their walls of 
nearly uniform thickness and without any obvious septal 
projections. 
The autopores are separated by one, two, or more rows 
of much narrower, polygonal mesopores v/hich fit closely 
together.
