two aiiiuili of the latter. Complete in segments 14, 15, and 

 the posterior part of J 3, and anteiior of 1 G ; saddle- 

 shaped in segment 17, and the posterior part of 10, and 

 anterior of 18. Bright pink colour when alive, the body 

 being flesh-coloured. 



Setse, four couples, regularly arranged. The rows of setse 

 of each couples in the anterioi- median part of the body 

 being very close together, and the outei- ones latero-ventral 

 in position. The rows gradually become wider apart 

 posteriorly. 



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

 interval between the rows of setre of the inner couples. 



Oviduct pores on segment 14, ventral of, and anterior to, 

 the level of the innermost sette. 



Spermathecal pores, two pairs, between segments 7 and 8, 

 8 and 9. 



Accessory copulatory structures. Swollen, round, tumid 

 patch between the male pores. In fiont of these, on segment 

 17, are two round elevations, each at the level of the inter- 

 val between the rows of the inner couples of seta3. Ellipti- 

 cal elevatiors, with median depressions, placed half on each 

 of the segments 19 and 20, 20 and 21,21 and 22, 22 and 28. 



Dorsal pores present, but not visible in front of the clitel- 

 lum, and may be obliterated in this. 



Nephridiopores at the level of the third row of setse. 



Alimentary canal. Gizzard in segment 5. Two large 

 pairs of calciferous glands m segments 15 and l(i. The 

 large intestine commences in segment 18. 



Circulatory system. Dorsal vessel single. The last heart 

 in segment 12 A supra-intestinal vessel present in the 

 region of the hearts. 



Excretory .system. Meganephric. 



Reproductive system. Two pairs of testes in segments 

 10 and 11, with r(>settes in the same segments. Prostates, 

 coiled, tubular, and in segments 17, 18, and 19. White 

 elevated patches are seen in segments 18, 19, 20, 21, and 22, 

 corresponding in position to the accessory copulatory 

 structures seen externally. Sperm sacs, grape-like, attached 

 to the anterior wall of segment 12. 



Ovaries in segment 13, into which also open the oviducts. 



Spermathecfe, two pairs in segments 8 and 9, each with a 

 large sac and small rosette-like diverticulum. 



Habitat. Wai-raoul, about one foot under oiovmd.
