Excretory system, meganephric. 



Reproductive system. One pair in segment 11 into which also 

 the ciliated rosettes open. 



Spermiducal glands, coiled, tubular in segments 18. 



Sperm sacs racemose, attached to the anterior wall of segment 

 12. 



Ovaries in segment 13, into which the oviducts also open. 



Spermathecae in segments 8 and 9, each consists of a sacular 

 part with a small mammilated diverticulum at the base of the 

 sac, and a notably long, curved duct. 



Habitat. Neerim and S. Warragul, amongst the Gippsland 

 Ranges, Victoria. 



(4). Megascolides tisdalli, sp. n. (Figs. 16, 17, 18). Spirit 

 specimens 3^ inches long, ^ inch broad. 



Prostomium completely dovetailed into the peristomium. 

 Marked by a longitudinal groove, which is continued backwards 

 along the mid dorsal line. 



Clitellum well marked, including segments 14-16 and the 

 dorsal part of the hinder half of segment 13 and the anterior 

 half of segment 17. Flesh coloured. 



Setae distinct, arranged in two pairs regularly, except at the 

 very hinder end (about the terminal ^ inch), where they are very 

 irregularly scattered, and where there may be as many as 7 on 

 each side, though most usually only 4 are present. In front of 

 this region the ventral pair is placed close to the ventral surface, 

 the lower seta of the outer pair about half way up the side, and 

 the upper seta near to the dorsal surface. 



Accessory copulatory structures in the form of three oval 

 glandular patches on the anterior edge of the mid ventral surfaces 

 of segments 9, 10, 11, and of two oval patches between segments 

 16 and 17. 



INIale pores on segment 18 ; penial setae present. 



Oviduct pores on segment 14. 



Spermathecal pores 5 in number, intersegmental, between 

 segments 4 and 5, 5 and 6, 6 and 7, 7 and 8, 8 and 9 ; at the 

 level of the ventralmost .setae. 



Dorsal pores present ; the first between segments 4 and 5. 



Nephridiopores at the level of the third seta on each side.
