Further Descriptions of Australian Earthworms. 39 



Setae regularly arranged, except at the very posterior end 

 (about 16 segments). Elsewhere the setae of each pair are close 

 together, the outer pair being placed about half way up the side 

 of the body. 



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

 ventral pairs of setae on segment 18. 



Oviduct pores on segment 14. 



Spermathecal pores, two pairs, at the level of the ventralmost 

 setae between segments 7 and 8, 8 and 9. 



Dorsal pores present ; the first between segments 5 and 6. 



Alimentary canal. Gizzard in segment 5 ; no vascular 

 swellings or calciferous glands ; large intestine commencing in 

 segment 19. 



Blood vascular system. Dorsal vessel single ; hearts in 

 segments 8-12. 



Excretory system. Meganephric. 



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

 11, into which the ciliated rosettes open. 



Spermiducal glands. Coiled, tubular ; in segment 18 ; a large 

 mass of glandular tissue in the mid ventral line between the 

 two glands. 



Sperm sacs. Racemose, attached to the anterior wall of 

 segment 12. 



Spermathecae, two pairs, each consisting of a sac with a very 

 small mammilated diverticulum close to the body wall. 



Habitat. S. Warragul, Victoria. 



(7). Megascolides volvens, sp. n. (Figs. 25, 26, 27.) 

 Spirit specimen 3-4 inches long, |^ inch l)road. 



Prostomium completely dovetailed into the peristomium. 



Clitellum well developed, extending over segments 14-16. 



Accessory copulatory structures ; an oval patch between 

 segments 17 and 18 at the level of the outer of the ventral pair 

 of setae ; another at the same level between segments 18 and 19, 

 and another at the level of the ventralmost setae between 

 segments 19 and 20. None of them are strongly marked. 



Setae, 4 on each side, regularly arranged, except in the last 25 

 segments. In front of the clitellun\ the ventral pair are close
