Excretory system. Meganephric ; the nephridiopores at the 

 level of the sixth setae ; the first on the third segment. 



Reproductive system. Two pairs of testes in segments 10 and 

 11, into which the ciliated rosettes open. 



Spermiducal glands, coiled, tubular, in segments 18 and 19. 



Sperm sacs, lobate, attached to the anterior walls of segments 

 11 and 12. 



Ovaries in segment 13, into which the oviduct opens. 



Spermathecae, 5 pairs, in segments 5-9, each consisting of a 

 tubular sac and short tubular diverticulum. 



Habitat. Mount Arnold, near Marysville, Victoria ; under 

 longs and sheets of bark on a small swamp. 



(11).. Diporochaeta fposti, sp. n. (Figs. 91, 92, 93). 

 Spirit specimens 1| inches long, ^ inch broad. 



Prostomium completely dovetailed into the peristomium, which 

 has a median ventral furrow. 



Clitellum extending over segments 14-16; dark purple tumid ; 

 accessory copulatory structures ; oval glandular patches in the 

 mid ventral line between segments 5 and 6, 6 and 7, 7 and 8, 8 

 and 9 ; three in the mid ventral line between segments 16 and 

 17, 17 and 18, 18 and 19, and two in the mid ventral line 

 between segments 19 and 20. 



Setae, 12 on each side in front of the clitellum, 13-14 in the 

 middle of the body, and 1 4 posteriorly ; dorsal and ventral break 

 distinct. 



Male pores on papillae on segment 18 at the level of the 

 interval between the two ventral setae on each side. 



Oviduct pores on segment 14. 



Spermathecal pores, 4 pairs, opening just dorsal at the level of 

 the ventralmost setae between segments 5 and 6, 6 and 7, 7 and 

 8, 8 and 9. 



Dorsal pores, the first between segments 4 and 5. 



Alimentary canal. Gizzard in segment 5 ; no vascular 

 swellings or calciferous glands ; a curious, large, swollen, white
