Had I been influenced by my own judgment, and not by 
Duncan’s, I should have continued to retain Hemiaster Archeri, 
Ten.-Woods, in Brissopsis, to which Duncan refers Cyclaster as a 
synonym. However, the characteristic, incomplete, simple, peri- 
petalous fasciole has already been described by me, and subse- 
quently figured by Bittner; the association therewith of an 
almost obsolete anterior groove may make it desirable to employ 
the name of Cyclaster for our species in place of Micraster or 
Lrissopsis as hitherto.

This is an interesting addition to the echinoid-fauna of the 
Australian Eocene, and is unrepresented in my collection.
