On the occurrence of the genus Palaeaster in the Upper Silurian rocks of Victoria
Abstract
The Upper Silurian rocks of Victoria have so far yielded two species of Asteroidea, and one well defined species of Ophiuroidea, whilst a second doubtful species of the latter class is believed to exist. The former are Petraster Smythii, McCoy, from the Moonee Ponds beds, and Urasterella Selwynii, McCoy, from near Kilmore. The single described species of the second class is Protaster brisingoides, Gregory, from Moonee Ponds, the doubtful one being a MS. name Toeniaster australis, McCoy. It has been suggested that this is merely a synonym of Gregory's P. brisingoides.
