Oviduct opening on segments 14. 



Spermathecal pores close to the mid dorsal line (dorsal of all 

 the setae) between segments 5 and 6, 6 and 7, 7 and 8, 8 and 9. 



Alimentary canal, circulatory system, excretory system, and 

 reproductive system similar to those of M. dorsalis, except that 

 the spermiducal glands extend over more segments (18-21). 



Habitat. Terang, Victoria. The species, as will be seen, is 

 closely allied to M. dorsalis, but is very clearly distinct from this 

 and all other species by the unique position (so far as yet known) 

 of the openings of the spermathecal glands. 



DipoPOchaeta, Beddard. 



(1). DipoPOchaeta davallia, sp. n. (Figs. 61, 62, 63). 

 Spirit specimens 8 inches long, |- inches broad ; number 

 of segments 158. 



Prostomium completely dovetailed into the peristomiuni. 



Clitellum extending over segments 13-17, but not including 

 the ventral parts of segments 16 and 17. Accessory copulatory 

 structures well developed, a pair of glandular patches at the level 

 of the two ventral setae on each, between segments 9 and 10, 15 

 and 16, 16 and 17, 19 and 20, 20 and 21, 21 and 22, a pair at 

 the level of the most ventral seta on each side, between segments 

 18 and 19, a pair at the level of the interval between the second 

 and third setae, each side between segments 17 and 18. 



Setae. Five on each side in the anterior segments, 9 in 

 segment 18, 10-12 in the next few segments, 14 in the middle 

 of the body, and 12-14 at the posterior end. 



Male pores, on segment 18 at the level of the interval between 

 the two ventral setae of each side. 



Oviduct pores on segment 14. 



Spermathecal pores, 5 pairs, at the level of the most ventral 

 seta of each side, between segments 4 and 5, 5 and 6, 6 and 7, 7 

 and 8, 8 and 9. 



Dorsal pores, the first between segments 3 and 4. 



Alimentary canal. Gizzard in segment 5 ; a small vascular 

 swelling in segment 13 and larger ones in segments 14 and 15 ; 

 no true calciferous glands ; large intestine, commencing in 

 segment 17.
