54 Proceedings of the Royal Society of Victoria. 



Circulatory system. Single dorsal vessel ; hearts in segments 

 6-12. 



Excretory system. Meganephric ; external openings at the 

 level of the tenth seta from the ventral surface on each side ; 

 peptonephridia present. 



Reproductive system. Testes, two pairs, in segments 10 and 

 11, into which the ciliated rosettes open. 



Spermiducal glands, tubular, in segment 18. 



Sperm sacs, racemose, attached to the posterior wall of 

 segment 9 and the anterior of segment 12. 



Ovaries in segment 13, into which also the oviducts open. 



Spermathecae, four pairs, in segments 6, 7, 8, and 9, each 

 consisting of a sac swollen at its end and a tubular diverticulum 

 half the length of the sac. 



Habitat. S. Warragul, Gippsland. When alive the worm is 

 dull reddish in colour with the clitellum well marked and cream 

 coloured. The body is flattened out from above downwards. 



(3). Dipopochaeta lindti, sp. n. (Figs. 67, 68, 69). Spirit 

 specimens 3 inches long, ^ inch broad ; number of 

 segments 126. 



Prostomium completely dovetailed into the peristoraium, which 

 has a median ventral furrow. 



Clitellum extending over segments 14-16 and the posterior 

 part of 13 ; accessory copulatory structures ; a pair of glandular 

 patches in the median, anterior and posterior surfaces of 

 segments 6, 7, and 8 and in the median anterior surfaces of 

 segments 9 and 10 ; larger ventral patches between segments 17 

 and 18, 18 and 19. 



Setae, from 6-10 on each side in front of the clitellum, 

 obliterated in the clitellum, behind this usually 12 on each side, 

 at the posterior end the ventral break is very small indeed. 



Male pores on segment 18 at the level of the interval between 

 the two ventral setae on each side. 



Oviduct pores on segment 14. 



Spermathecal pores, 5 pairs, at the level of the interval between 

 the two ventral setae on each side between segments 4 and 5, 5 

 and 6, 6 and 7, 7 and 8, 8 and 9. 



Dorsal pores, the first between segments 3 and 4.
