The small fragment placed at my disj)osal, which I consider as belonging 
to this species, possesses so perfectly the shape and characteristics given it hy 
McCoy, that I cannot believe myself mistaken in its identity. The coenoecium 
is composed of parallel branches, rarely bifurcating, the breadth of which 
equals that of the fenestrules. The fenestrules are oval, slightly elongated 
or subcircular ; the crossbars which give rise to them are thin and arched 
from the two sides. The porous surface is ornamented with three rows of non- 
marginated cells, arranged quincuncially. According to McCoy the posterior 
surface, which I was unable to see, is smooth, except for some small pores 
placed at the point of origin of most of the crossbars. 
Horizon and Localities. — A single specimen of this species, the 
existence of which in the Carboniferous Limestone of Ireland was first 
recorded by McCoy, was found by Mr. W. B. Clarke in a dark-grey lime- 
stone at Buchan.
