III.—Studies in Edrioasteroidea, IX. The Genetic Relations to other Echinoderms

Published online by Cambridge University Press:  01 May 2009

Extract

The last Study brought out many resemblances between Edrioasteroidea and Asteroidea, much closer than have been recognized even by some who have suggested a derivation of the latter Class from the former. In the present Study it is proposed to inquire whether that hypothesis, or any similar hypothesis, is tenable.
