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



11 into which also open the ciliated rosettes. 

 Prostates tulular, coiled, occupying segments 17-20. 



Sperm sacs, racemose, attached to the anterior face of segment

Ovaries in segment 13 into which the oviducts also open. 

 Ovisacs (or additional ovary?) in segment 14.

 extending slightly into the dorsal surface of segment 18, and 

 incomplete ventrally in the median part of segment 17. 



Setae, the inner couple close together, the dorsal couple not 

 visible. 



Male pores on a papilla on segment 18 at the level of the 

 interval between the inner couple of setfe on each side. 



Spermathecal pores, two pairs, on white elliptical patches on 

 the anterior margins of segments 7 and 8, at the level of the 

 interval between the two inner setai of each side. 



Accessory copulatory structures. Swollen, tumid ridges on 

 segments 18, 19 and 20. 



Dorsal pores present, the first between segments 3 and 4. 



Nephridiopores not discernible. 



Alimentary canal. Gizzard in segment 5. No true calciferous 

 glands, but vascular swellings in segments 9-1-4. In segment 9 

 the canal is especially swollen and whitish in appearance. Large
