Clitellum, when fully matui-e, includes segments 13-18, 

 but when not fully developed, •)nly includes the posterior- 

 part of 13, and the anterior of 18. 



Setse arranged regularly in four couples, the rows of the 

 outer couple, which is lateral in ])osition, being about twice 

 as far from one another as those of the inner couple. 



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

 the interval between the setse of the inner couples. 



Oviduct pores on small papilla3 on segment 14, anterior to, 

 and ventral of, the level of the innermost setae. 



Spermathecal pores, two pairs on slight papillge in the 

 anterior part of segments 8 and ,9, at the level of the interval 

 between the set?e of the inner couples. 



Accessory copulatory structures. A round tumid patch 

 between the male pores. Elliptical elevations, with 

 median depressions, situated at the level of the intervals 

 between the set?e of the inner couples, and placed half on 

 each of the segments 16 and 17, 19 and 20, 20 and 21, 

 21 and 22, 22 and 23. 



Alimentary canal. Gizzard in segment Ci. No true 

 calciferous glands and no well marked vascular swellings. 

 Lurge intestine commences in segment 18. 



Circulatory system. Dorsal vessel single. Hearts in 

 segments 6-12, those in segments 6-8 small. 



Excretory system. Meganephric. 



Reproductive system. Testes, two pairs in segments 

 10 and II, rosettes opening into the same segments. 

 Prostates, coiled, tubular, and in segment 18. Sperm sacs, 

 grape-like, attached to the anterior wall of segment 12, and 

 the posterior wall of segment 9. 



Ovaries in segment 13, the oviducts opening into the 

 same segment. 



Spermatheccie, two pairs in segments 8 and 9, each 

 consisting of a lai'ge sac with a vei-y small diverticulum 

 scarcely noticeable. 



Habitat. Victoria (exact locality unknown). 



(8) Megascolides sinaosus, sp. n. (Figb. 55, oQ, 57). Length 

 of spirit specimen 20 inches, slightly more than one- 

 quarter inch broad. 

 Prostoniiura not at all dovetailed into the peristomiuni. 

 Clitellum only indicated by a slight colouration (in spirit) 

 in the region about the genital openings, where also ridges 

 are pi-esent.
