Phyllodocid^. 



At the end of Part II of this work I announced the dis- 

 covery in the Phyllodocidge of closed nephridia provided with 

 solenocytes, and, indeed, it so happens that in this family 

 are found some of the most beautiful examples of this type of 

 excretory organ. 



The Phyllodocidse are divided into two sub-families, the 

 Alciopinse and the Phyllodocinse. Of the Alciopinae I have 

 been able to study fresh and preserved specimens of Al- 

 ciope cantrainii, D. Ch., A. Krohnii, Gruff, Asterope 

 Candida, D. Ch., Vanadis formosa, Clp., at the Zoolo- 

 gical Station at Naples. 



Amongst the Phyllodocinse I have examined more espe- 

 cially fresh and preserved examples of Phyllodoce Pa- 

 retti, Blainv., Ph. laminosa, Sav., Eulalia punctifera, 

 Gr., Eteone lactea, Clp., from Plymouth, and a spirit 

 specimen of Eteone siphonodonta, D. Ch., from Naples. 



I Part I appeared in vol. xl (1897), and Part II in vol. xli (1898) of this 

 Journal. Por the contents of Parts I, II, and III see the table at the end of 

 this paper.
