Fig. 9. — Funnel of same, showing arrangement of the 20 

 marginal cells, and the cubic-shaped cells lining the 

 duct from the funnel. 



10. — Somewhat diagrammatic transverse section through 

 coils of a nepridium, showing pigment granules 

 (p.g. ) in the cells lining the pigmented coil. 



11. — Diporochaeta grafidis. Drawing of nephridium, mount- 

 ed whole in glycerine. 

 12. — Megascolides austral is. Diagram of arrangement of 

 meganephridia in part of a specimen. From 160 

 to 180 only a few large nephridia are present, 

 most of which (N^) though attached to the anterior 

 septum, have no funnel. 



13, — Diagrammatic transverse section of same near posterior 

 end of body, to show arrangement in one section of 

 the mega- and micronephridia and the ducts for 

 them. 



14. — Diagrammatic longitudinal section of same where 

 meganephridia are beginning to become irregular, 

 showiiii; arrangement of ducts from mega and 

 micronephridia, and their connection on their way 

 to the exterior. 



15. — Diagrammatic longitudinal section showing same near 

 posterior end. 



16. — Woodwardia ^ippslandica. Diagram of five mega- 

 nephridia in situ on left-hand side of body, to show 

 relative positions and size of funnel (F), nephridial 

 coils (c.n.), vesicle (Y), and opening to exterior. 



17. — Diagrammatic nephridium of same, showing relation 

 of the several parts to one another. 



18. — Woodwardia coorauiensis. External view, showing 

 positions of openings of the nephridia and their 

 relation to the setae. 



19. — 8emi-diagrannnatic di-awing near posterior end of body 

 of same, to show six nephridia in situ with those on 

 right-hand side of body, opening opposite 2nd seta 

 (A) and opposite 4th seta (B) alternately. 



20. — Enlargement of same, showing two consecutive neph- 

 lidia and their various parts.
