Accessory copulatory structures. Three pairs of elliptical 

 tumid patclies on segments 9, 10 and 11, each placed at the 

 posterior end of the segment at the level of the second setaj. 

 Dorsal pores not visible. 



Nephridiopores 10 in each segment. One just in front of each 

 seta, and one between setffi 3 and 4 on each side. 



Alimentary canal. Gizzard in segment 5. No true calciferous 

 glands. Large intestine commencing in segment 17. 



Excretory system. Five nephridia on each side in each 

 segment, corresponding in position to the setse, with an extra 

 one between the third and fourth setae. No ciliated funnels 

 discernible. 



Reproductive organs. Testes, two pairs, one in segment 10, 

 another in segment 11. Rosettes in the same segments. 



Prostates, large, tubular, somewhat coiled. Extending through 

 segments 18-21. 



Sperm sacs, racemose on the anterior septum of segment 12, 

 and the posterior of segment 9. 



Ovaries in segment 13. Oviducts opening into the same 

 segment. 



Spermathecce, two pairs, each with a simple diverticulum about 

 one-quarter the length of the sac. 



Circulatory system. Single dorsal vessel. Hearts in segments 

 4-13. In segments 4-9 are small and arise from the dorsal vessel, 

 in segments 9-13 lai'ge, and arise from the supra-intestinal 

 vessel which extends through segments 9-13. 



Habitat. Mount Wellington, Hobart, and Parattah, Tasmania. 



(3). C. mortoni. Length in spirits, 2i-3 inches, one-quarter inch 

 broad. In spirit the worm is a flesh colour, and broad iu 

 comparison to its length. (Figs. 7, 8, 9). 



Prostomium completely dovetailed into the peristomium. 



Clitellum well marked, extending over segments 14-17, some- 

 what darker than the rest of the body in spirit specimens. Tumid. 



Setifi regularly arranged in four couples, the intervals between 

 the two couples nearly equal and slightly greater than that 

 between sette 2 and 3. 



j\lale pores on papill?e on segment 18 just dorsal to the level 

 of the innermost sette.
