Clitellum well marked, complete, occupying segments 

 14, 15, 16. 



Setae, in front of the clitellum, 10-11 each side ; behind 

 the clitellum, 13 each side. The rows regular. 



Male i)ores on two fairly well marked papillae on segment 

 18, at the level of the interval between the second and third 

 setfe of each side. 



Oviduct pores on segment 14 slightly anterior to, and 

 ventral of, the level of the setae. 



Spermathecal pores, four pairs, between segments 5 and 6, 

 6 and 7, 7 and 8, 8 and 9, at the level of the innermost seta3 

 of each side. 



Accessory copulatory structures. Two ridges with swollen 

 ends, one immediately in front of, the other immediately 

 behinil, the male openings. Both have their swollen ends 

 at the level of the intei val between the two inner setae of 

 each side. One is placed half on each of the segments 

 17 and 18, the other half on each of the segments 18 and JO. 

 A smaller ridge with two confluent swellings, half on each of 

 segments 16 and 17, and situated in the mid-ventral space 

 between the innermost rows of setae. Two elliijtical tumid 

 patches in the mid-ventral space, one on the posterior half of 

 segment 7, the other on the posterior half of segment 8. 



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



Nephridiopores very prominent, at the level of the seventh 

 seta of each side, and placed at the anterior margin of each 

 segment, commencing with the third. On contraction in 

 s]3irit, the body wall in transverse section has the form of an 

 upper and lower half, meeting on each side at an angle 

 which corresponds in position to the nephridiopore. 



Alimentary canal. Gizzard in segment 5. No true 

 calciferous glands, but large vascular swellings in segments 

 14 and 15, and smaller ones in segments 9-13. Large 

 intestine commencing in segment 17. 



Circulatory system. Dorsal vessel single. Last heart in 

 segment 12. 



Excretory system. Megan ephric. 



Reproductive system. Two pairs of testes in segments 

 1 and 1 ] , into which open the rosettes. 



Prostates tubular, coiled, in segment 18. 



Sperm sacs, two pairs, one attached to the anterior wall 

 of segment 12, the other to the posterior wall of segment 9. 

 Sac-like in form.
