7 and 8; median ventral patches on segments 10-12, and on

 small. In front of clitellum 14-15 setae on each side. 



Male pores on papillae on segment 18. 



Oviduct pores on an oval glandular patch on segment 14, close 

 to the raid ventral line. 



Spermathecal pores, two pairs, on little oval patches at the 

 level of the interval between the fifth and sixth setae on each 

 side between segments 7 and 8, 8 and 9. 



Dorsal pores, the first between segments 3 and 4. 



Alimentary canal. Gizzard in segment 5 ; vascular swellings 

 in segments 10, 11, 12 and 13 ; no true calciferous glands present ;

 11, into which the ciliated rosettes open. 



Spermiducal glands, flattened, bilobed, 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 the oviducts open.

 of a tubular sac with a diverticulum about three-quarters the 

 length of the sac. 



Habitat. Cooran, Queensland. 



(9). Megascolex teicangiensis, sp. n. 



Prostomium about one-half dovetailed into the peristomium. 



Clitellum extending over segments 14-16. Accessory copu- 

 latory structures, a pair of glandular patches at the level of the 

 interval between the two ventral setae on each side on segment 

 17, a small patch just in front of the male opening on each side. 



Setae, 7-8 on each side in front of the clitellum. 



Male openings on prominent papillae on segment 18 at the
