In this (var. mucronata) the only difference we have been able to 
detect is to be seen in the pygidium, in which the posterior border 
instead of being rounded is produced into a short blunt mucro. 
Formation.—Carboniferous Limestone.

ston, Fife.

Although I have been unable to trace the original specimen, 
which forms the basis of Prof. Phillips’ figure and description of 
Phillipsia quadrilimba, I have allowed it to stand in case it may 
hereafter be found, and may prove to be a good and distinct species.
