Clitellum extending over segments 13-17, though only the 

 posterior pai't of 13 may be included. 



Accessory copulatory structures. Glandular patches ventrally 

 on segments 10, 11 and 12. 



Setae with a distinct dorsal and ventral break, 12-16 on each 

 side. 



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

 interval between the two ventral setae on each side. 



Oviduct pores on segment 14, very close to the mid ventral 

 line on a white glandular area. 



Spermathecal pores. Two pairs, between segments 7 and 8, 

 8 and 9, at the level of the second seta on each side. 



Dorsal pore, the first between segments 5 and 6. 



Alimentary canal. Gizzard in segment 3, vascular swellings 

 in segments 8, 9 and 10. No true calciferous glands. Large 

 intestine, beginning in segment 16. 



Circulatory system. Single dorsal vessel. Hearts in segments 

 5-12, those in segments 5-9 smaller than the three last pairs. 



Excretory system. Plectonephi'ic. 



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

 11, into which the ciliated rosettes open. 



Spermiducal glands. Flattened, bilobed, in segment 18, or 

 may also press forward into segment 17. 



Sperm sacs. Racemose, attached to the posterior wall of 

 segment 9, and the anterior of segment 12. Sperm reservoirs 

 may be present in segments 10 and 11, but these do not enclose 

 the rosettes. 



Ovaries in segment 14, into which the oviducts open. 



Spermathecae, two pains, in segments 8 and 9 ; each consists of 

 a sac and tubular diverticulum swollen at its end. 



Habitat. Cooran and Gayndah, Queensland. 



(8). Megascolex iliidgei, sp. n. (Figs. 58, 59, 60.) Spirit 

 specimens 2^ inches long, ^ inch broad ; the body 

 containing about 88 segments. 



Prostomium about one-half dovetailed into the peristomium. 



Clitellum, extending over segments 14-16. Accessory copula- 

 tory structures, well developed ; small patches between the level 

 of the fourth and fifth setae on each side ventrally, on segments
