With respect to the steps by which these curious organs have been evolved, Mr. Agassiz infers from his own researches and those of Mr. Muller, that both in star-fishes and sea-urchins the pedicellariae must undoubtedly be looked at as modified spines.
Organo bitxiok garatzeko iraganiko urratsei dagokienez, Agassiz jaunak, bere eta Müllerren ikerketetatik, inferitzen du pedizelarioak, hala itsasizar nola itsastrikuetan, arantza eraldatutzat jo behar direla.
