Further Descriptions of Australian Earthworms. 65 



Reproductive system. One pair of testes in segment 11, into 

 which open the ciliated rosettes. 



Spermiducal glands, coiled, tubular, in segment 18. 



Sperm sacs, racemose, attached to the anterior wall of 

 segment 12. 



Ovaries in segment 13, into which the oviducts open. 



Spermathecae, two pairs, each consisting of a long, bent, 

 tubular sac, with a very short, blunt, diverticulum, in segments 8 

 and 9. 



Habitat. Warrandyte, Victoria. (Collected by Mr. C. M. 

 Maplestone). The number of setae on each side is very few, 

 being usually 6. In front of the clitellum there are two 

 pairs, but behind the clitellum all except the ventral pair are 

 irregularly arranged. This species is doubtfully associated with 

 Diporochaeta. 



Digastep, Perrier. 



(1). Digastep minop, sp. n. (Figs. 100, 101, 102.) Spirit 

 specimens 1\ inches long, less than ^ inch broad ; about 

 143 segments. 



Prostomium dovetailed about one-half into the peristomium. 



Clitellum extending over segments 14-18 and the posterior part 

 of 13 ; accessory copulatory structures ; a broad, glandular patch 

 ventrally on segment 19. 



Setae, two pairs on each side regularly arranged, the two of 

 the lateral pair twice as far apart as those of the ventral pair. 



Male pores on an oval patch on segment 18 at the level of the 

 ventral seta on each side. 



Oviduct pores on segment 14. 



Spermathecal pores on small oval patches just ventral of the 

 level of the ventral setae between segments 7 and 8, 8 and 9. 



Dorsal pores, the first between segments 7 and 8. 



Alimentary canal. Two gizzards in segments 6 and 7 ; no 

 vascular swellings or calciferous glands; large intestine, com- 

 mencing in segment 17. 



Circulatory system. Dorsal vessel single ; hearts in segments 

 8-12. 



Excretory system. Plectonephric.
