Further Descriptions of AustraUaii Earthworms. 35 



Spermiducal glands, small, coiled, tubular, in segment 18. 



Sperm sacs, racemose, attached to the anterior wall of segment 

 12. 



Spei'mathecae, in segments 8 and 9. Each consists of a long 

 sac with a very small blunt diverticulum. 



Habitat. — Warragul (Victoria). Collected by Mr. T. Steel. 



(3). Megascolides eucalypti, sp. n. (Figs. 13, 14, 15). 

 Spirit specimens, length 8^ inches. 



Prostomium completely dovetailed into the peristomium. 



Clitellum well developed including the posterior two-thirds of 

 segment 13, segments 14, 15, 16, 17, and the anterior two-thirds 

 of segment 18. The anterior part (on segment 13), and the 

 posterior (on segment 18), white and tumid, the intermediate 

 part darker coloured. The mid ventral surface of segments 17 

 and 18 not included. Accessory copulatory structures in the 

 form of two pairs of papillae at the level of the ventral setae, the 

 front one between segments 18 and 19, the hinder one between 

 segments 19 and 20. 



Setse regulai'ly ari-anged, two pairs on each side, the setae of 

 each pair close together. 



Male pores on papillae on segment 18 at the level of the inter- 

 val between the ventral pair of setae. Penial setae present. 

 Oviduct pores on segment 14. 



Spermathecal pores, two pairs, intei'segmental, at the level of 

 the ventralmost setae, between segments 7 and 8, 8 and 9. 



Dorsal pores present, the most anterior between segments 4 

 and 5, though usually the first one visible is further back, often 

 between segments 12 and 13. 



Nephridiopores on the very anterior margin of the segments at 

 the level of the third setae on each side, the most anterior one on 

 the anterior margin of segment 5. 



Alimentary canal. Gizzard in segment 5, vascular swellings in 

 segments 15 and 16, no true calciferous glands. Large intestine 

 commencing in segment 19. 



Blood vascular system. Dorsal vessel single. Heai'ts in seg- 

 ments 8-12. A well-marked lateral longitudinal vessel in seg- 

 ments 8-19 at the level of the nephridia.
