As far as they go these figures seem to prove that on both the 
Western and Eastern coasts of Australia Echini are unusually 
numerous, while the number of Crinoids found in Western Aus- 
tralia is a long way above the normal. 
A list of all the identified Echinoderms in the Museum, with 
their localities when known, is attached. In addition to the 
sources already referred to, Dr. Michaelsen has presented a number 
of Ophiurans and Crinoids collected in this State by the Hamburg 
Expedition in 1905. These are included in the list. 
[The Classification followed is that of Bronn’s “ Tier-reichs ” 
for all the groups except the Crinoids. The later class are arranged 
according to Mr. A. H. Clark’s Monograph of the Recent Crinoids 
of Australia.]
