"Palolo" was made independently by Kramer and Friedlaender, although the latter was the first to publish an account of his investiga- tions. Friedlaender succeeded in obtaining from the reef-rock at Sama- tau several specimens of " Palolo," together with the head ends of an annelid of different appearance and much larger size belonging to the genus Eunice. Friedlaender was the pioneer, for he was the first to iden- tify the large head-end as that of a Eunice, and was the first to figure it as well as the transition piece be- tween it and the " Palolo," and it was from his material that Ehlers gave us the final name Eunice viri- dis (Gray). All that I can hope to do is to establish, beyond doubt, the origin of the " Palolo," and confirm the researches of Friedlaender and Kramer, and add something to our knowledge of the morphology, habits, and relationships of this once mys- terious worm. It was Ehlers (1898) who first gave a detailed description of the Palolo worm and recognized an ex- treme case of sexual dimorphism, and showed the " Palolo " to be the epi- tokal posterior portion of Eunice viridis (Gray). He says (1898), " Ich erganze das im Voraus damit, dass ich die Eunice, die nun den Namen Eunice viridis (Gray) erhalt, in den Kreis der Eunice siciliensis Gr. bringe und an ihr die Ausbildung des " Palolo " als eine Form der Epitokie auffasse, wie sie zum ersten Male aus der Familie der Euniciden, und in ihrer Besonderheit abwei- chend von alien Erscheinungen der Epitokie, die von Borstenwtirmem bekannt sind, sich darstellt. Demnach ist in der Art eine atoke und epitoke Form, in der letzteren eine atoke und epitoke Korperstrecke zu ; We have then in the Palolo, combined in the same in- dividual, an atokal and an epitokal part corresponding to the anter
