Further Descriptions of Australian Eartlnvornis. 59 



Excretory system. Meganephric. Peptonephridia present. 



Reproductive system. Two of pairs testes in segments 10 and 

 11, into which the ciliated I'osettes open. 



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

 the duct long and coiled. 



Sperm sacs, lobate, finger-shaped, attached to the posterior 

 wall of segment 9 and the anterior of segment 12. 



Ovaries in segment 13, into which the oviducts open. 



Spermathecae, five pairs in segments 5-9. 



Habitat. Loch, Gippsland, Victoria. 



(8). Diporochaeta nemopalis, sp. n. (Figs. 82, 83, 84). 

 Spirit specimens 2| to 3 inches long, jr inch broad. 



Prostomium about half dovetailed into the peristomium. 



Clitellum extending over segments 14-16 and the posterior 

 part of 13, tumid, almost concealing the setae, and quite 

 concealing the dorsal pores. Accessory copulatory structures, 

 glandular patches at the level of the interval between the two 

 ventral setae on each side between segments 16 and 17 and at 

 the same level on the anterior part of segment 19. 



Setae, usual number in front of the clitellum ten on each side ; 

 in the middle of the body 11-12, at the posterior end vary much, 

 11-21 : in this part, odd ones may lie very close to the mid dorsal 

 line so that the dorsal break is very irregular and may be 

 scarcely noticeable : elsewhere the dorsal and ventral breaks ai'e 

 distinct. 



Male pores on papillae, at the level of the interval between 

 the second and third setae on each side. 



Oviduct pores on segment 14. 



Spermathecal pores. Five pairs, at the level of the interval 

 between the third and fourth setae on each side from the 

 ventral surface, between segments 4 and 4, 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, large intestine commencing in segment 17. 



Circulatory system. Single dorsal vessel, hearts in segments 

 7-12.
