Cover Illustration: Parallel switches in larval
nutrition have resulted in extensive parallelisms in larval morphology within the sea urchins
(Echinodermata: Echinoidea). Phylogenetic analyses of larval morphology
highlight the degree of convergence in larval form and suggest a model
for its origin. (See Wray, pages 308--322.)
