116 CAE-BONITEROUS CORALS AND ’ BRACHIOPODS 
Caninia, the genus Campophyllum embraces those simple 
cyathophyllids which have broad central tabula, in which 
there are no fossular depressions, whilst bilateral symmetry 
is only suggested by a very slight variation, in length, or 
spacing, of the septa at one point in the septal ring. 
The relationship of this genus to cyathophyllids of the 
type of O. dianthoides, McCoy, and to the genus Diphyphyl- 
lum is very close. 
Campophyllum aff Murchiaoni, Ed. and H. PI. 1, Fig. 5. 
Two specimens in the collection may be referred to this 
species, though the septa are less numerous than in the 
type. The one is a horizontal section, about 3 cm. in 
diameter, with a central tabulate area, 14 mm. broad, and 
a narrow outer ring, composed of coarse vesicular tissue 
bounded by a well marked outer wall. This outer zone 
maintains a constant width of about 8 mm. There are 
forty-four septa, short and approximately equal, which 
do not obviously extend across the outer vesicular zone 
and do not extend far, as striae, over the central tabulate 
area. Bilateral symmetry is only suggested by a shorter 
septum at one point of the septal ring. Very short rudi- 
mentary intermediates project inwards from the inner wall. 
The corallum is probably cylindrical, and its epitheca 
bears well-marked longitudinal striae. 
This specimen is figured, natural size ; it was probably 
derived from the uppermost beds. 
The other specimen is a narrow cylindrical form cut 
in half vertically and polished at both ends, so that it 
exhibits both horizontal and vertical sections. 
The horizontal section has a diameter of 23 mm. with 
a central tabulate area 10 J mm. broad. The narrow 
outer zone is composed of coarse vesicles and is indistinctly 
radiated by septal prolongations and by an intermediate 
septal series.
