Re)3roductive system. Single pair of testes in segment 1 1 ; 

 two pairs of rosettes, one in each of segments 10 and 11. 



Prostates, flatted bodies with mammillated surface in 

 segment 18. 



Sperm sacs, grape-like, attached to the anterior wall of 

 segment 1 2. 



Ovaries in segment 13, into which the oviducts open. 



SpermathecsB, two pairs in segments 8 and 9. Each 

 consists of a moderately long sac, with a small blunt 

 diverticulum. 



Habitat. Dandenong Ranges. Collected by Mr. Joseph 

 Hulme. 



I have much pleasure in associating the name of Mr. 

 Joseph Hulme with this interesting form. I am indebted 

 to that gentleman for a valuable collection of earth-worms, 

 including no fewer than four new species of the genus 

 Megascolides, as at present described. This form ranks next 

 in length to the giant Gippsland earth-worm. 



{4) Megascolides obscurus, sp. n. (Figs. 43, -1-t, 45, 77). 

 Length of spirit specimens IG inches, one-half inch 

 broad. One incomplete specimen measures 17 inches, 

 so that probably the above is a minimum length, 

 though the specimen is mature. 



Prostomium feebly developed, and not at all dovetailed 

 into the peristomium. 



Clitellum ])urple in spirit specimens. Lines of the 

 segments not obliterated, and the position of the seta? 

 marked by minute papillfe. Extends over segments ] 4-1 8, 

 and includes also the posterior part of segment 13, and the 

 anterior of segment 1 9. 



Setffi in four couples, difficult to see, except the inner two 

 pairs. Regularly arranged (?) 



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

 interval between the rows of the inner couj)les. 



Oviduct pores on segment 14. 



Spermathecal pores, two pairs between segments 7 and 8, 

 8 and 9, at the level of the innermost setiie. 



Accessory copulatory structures in the form of })rominent 

 ridges, the first half on segments 13 and 14, the second in 

 segment 18, and the third and foui'th half on segments 

 19 and 20, 20 and 21. 



Dorsal pores present, the first between segments 5 and U.
