Circuliitory system. Single dorsal vessel. Hearts in segments 

 6-12, those in segments 9-12 larger than the rest, and connected 

 with the supra-intestinal vessel. 



Excretory system. Plectonephric, with no large nephridia. 



Reproductive system. Testes, two pairs, in segments 10 and 

 1 1 , the ciliated rosettes opening into the same segments. 



Prostates, flattened, racemose surface, in segment 18. 



Sperm sacs in segments 9 and 1 2 ; racemose. 



Ovaries in segment 13 into which also the oviducts open. 



Spermathecae, two pairs, in segments 8 and 9. The diverti- 

 culum distinct and rosette shaped. 



Habitat. Mount Wellington. Tasmania. 



(10). C. (ifficeri {Vv^s. 28, 29, 30). Length in spirit 1| incli, less 

 than one-quarter inch broad. In spirit the body is a 

 light violet colour dorsally, and flesh colour ventrally, the 

 clitellum being darkei- tlian tlie I'est. 



Prostoniiuiu about thrco-ijuarters dovetailed into the peristo- 

 niium. 



Clitellum distinct, tumid, complete, extending o\er segments 

 14-17. Purple colour, except the mid-ventral surfaces of 

 segments 15, 16 and 17 where it is light coloured. 



Setty in four couples. Irregular at the posterior end. About 

 one-third of the way down the body the fourth row becomes 

 irregular, then the third and at the very posterior end all four 

 rows may be irregulai', but the lirst and second are quite regular 

 except during the last few segments. 



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

 second seta on each side. 



Oviduct pores on .segment 14. 



Spermathecal pores, three pairs placed slightly dorsal to the 

 level of the second low of setjv between segments 6 and 7, 

 7 and 8, 8 and 9. 



Accessory copulatory structures. Elliptical patches at the 

 level of the second row of setai between segments 15 and 16, 

 16 and 17. A pair at the level of the intciwal between the two 

 inner seta; between segments 19 and 20. 



Dorsal pores present, the tirst between segments 4 and 5. 



Nephridiopores not visible.
