Through the kindness of Dr. C. Anderson, Director of the Australian
Museum, a collection of Echinodermata of more than ordinary
interest was sent to me for identification in April, 1925. They were
largely collected by Surgeon Lieutenant-Commander W. E. .J. Paradice,
R.A.N. (late H.M.A.S." Geranium "), and chiefly on little known
portions of the Great Barrier Reef, Queensland, between 17° and 19° S.
lat. A few other localities are, however, represented. As several
of the species have not hitherto been taken on the coast of Australia, and
the records for many others show important extensions of range it seems
to me worth while to publish an annotated list of the species contained in
the collection. I sincerely thank Dr. Anderson for the opportunity to
examine this material and I would add that credit is due Dr. Paradice
for the important contribution he has made to our knowledge of the
Australian marine fauna. There are in the collection altogether 101
specimens, representing 42 species.
