il. PREFACE. 
The Echinoidea, which unfortunately is the smallest part of 
our collection of Echinodermata, is but poorly represented in 
Australia ; nevertheless, the Australian Region is the stronghold 
of some of the genera, as Salmacis, Amblypneustes, Goniocidaris, 
and Phyllacanthus, of which last all the known species are found 
within the Australian waters. Of the family Goniocidaride, 
out of fifteen species recorded by Proressor A. Aqasstz, ten © 
are found in the Australian Region. The Echinometride of 
Gray are also strongly represented by the occurrence of seven 
out of the eight genera known; of the family Temnopleuride 
(Dzs.), the genera Temnopleurus (Acass.), Salmacis (AGAss.), 
Mespilia (Des.), Amblypneustes (Acass.), and Holopneustes 
(Agass.), are Australian. 
The Clypeastride (AaGass.) are not well represented, for out 
of about eighteen genera only eight are to be found, represented 
by fourteen out of about fifty species known. One genus, 
Anomalanthus, the locality of which is yet uncertain, is the only 
genus peculiar to the Australian Region, 7.e, taking the 
Peronella of Gray to be not distinct from Laganum. 
Of the Petalosticha, probably only three genera, Hupatagus, 
Lovenia, and Breynia may be considered as being peculiar to 
the Australian Seas. 
The Asteroidea, Ophiuroidea, Crinoidea, and Holothuroidea will 
form the subject of other parts of this Catalogue, to be published 
as determined hereafter. 
Appended will be found a few notes and remarks on the 
Australian species, which may not prove uninteresting to the 
general reader. 
I have only to add that the abbreviation ‘ Pres.” signifies 
Presented ; ‘‘ Bght.,” Purchased; ‘Coll.,”” Collected by the 
Museum Collectors or Employees; ‘“ Exch,” received in 
Exchange ; while “ O.C.” is used to indicate that the specimen 
is from the Old Collection in the Museum prior to 1870. 
Throughout the Catalogue will be found mentioned some of 
the genera and species which we are most desirous of obtaining, 
these and any others not enumerated will be welcome additions 
to the Collection, and in return for which we shall be very happy 
to send duplicates of Australian species.
