Further Descriptions of Australian Earthtvorms. 37 



Alimentary canal. Gizzard in segment 15. Vascular swellings 

 in segments 8 to 13, the posterior ones being more marked than 

 the anterior. Behind segment 13 the oesophagus gradually 

 increases in size until it passes into the large intestine in segment 

 17. No true calciferous glands. 



Blood vascular system. Dorsal vessel single, hearts in 

 segments 7-12, the posterior three being larger than the anterior 

 ones. 



Excretory system. Meganephric. 



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

 11 ; ciliated rosettes opening into the same segment. 



Spermiducal glands. Coiled, tubular in segments 18-21. 



Sperm sacs. Long, 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, 6, 7, 8 and 9. 

 Each consists of a long sac with a short tubular diverticulum. 



Habitat. Walhalla, Victoria. Under logs in damp earth. 

 The doi^sal surface of the body a dark purple, the ventral dull 

 fleshy brown ; the clitellum flesh colour. 



(5). Megascolides punctatus, sp. n. (Figs. 19, 20, 21). 

 Spirit specimens 5 inches long, |- inch broad. 



Prostomium completely dovetailed into the peristomium. 



Clitellum well marked, extending over segments 14-16. 



Accessory copulatory structures very distinct ; two pairs of 

 prominent oval, white, glandular patches, one at the very 

 posterior margin of segment 7 ventrally, and the other on 

 segment 8. Small glandular patches (Fig. 19) ventrally on 

 segments 16-21. 



Setae. Two pairs on each side, regularly arranged, except at 

 the posterior end The upper seta of the outer pair gradually 

 assumes a more dorsal position towards the hinder end of the 

 body, when it comes to lie close to the mid dorsal line. At the 

 hinder end of the body the arrangement of all the setae is 

 irregular. 



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

 interval between the two ventral setae.
