 interval between the two venti-al setae on each side. 



Oviduct pores on segment 14. 



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

 and 9, at the level of the interval between the two ventral setae 

 on each side.

Alimentary canal. Gizzard in segment 5. Calciferous glands 

 in segments 10, 11 and 12. Large intestine, commencing in seg- 

 ment 16. 



Circulatory system. Dorsal vessel single. Hearts in segments

Reproductive system. Testes, two pairs in segments 10 and 

 11, with which also the ciliated rosettes open. 



Spermiducal glands flattened, small, lobulate, in segment 18. 



Sperm sacs racemose, attached to the posterior wall of segment 

 9, and the anterior of segment 12.
