Abstract
So far pedicellariæ are unknown in echinoids older than Carboniferous. The Silurian echinoid with which pedicellariæ occur has been recorded by Sherrard1, and is now catalogued as F18554 in the University of New England Palæontological Collection. It was collected from Vallance's Hill, Portion 177, Par. Namina, some 12 miles south-east of Yass, New South Wales, from rocks regarded as Ludlovian in age.
