The first plates to originate are the terminals. The dorsocentral 
originates after the genitals, before any plates on the actinal hemisome. 
Genitals of Asterias are homologous with “basals” of Amphiura : 1st 
interbrachial (odontophore) with orals of Amphiura. Madreporic 
opening not in homologous plates in Asterias and Amphiura .

As regards the nervous system, the author supports Carpenter and 
Marshall, but is opposed to Jickeli, Perrier, and Vogt. The mesodermal 
oesophageal ring, with its branches, is phylogenetically a part of the epi- 
thelial nervous system which has come to lie in the connective tissue.
