 inches, \ inch broad. Colour when alive whitish with pink 

 clitelluin, the same colour retained, only duller, in spirits. 



Prostomiuni dovetailed about \ into the peristomiura. 



Clitelluni distinct, tumid, occupying segments 13-17, but not 

 the whole of 17 ventrally, so that at its posterior end it is slightly 

 saddle-shaped. 



Seta3 in four couples, regularly arranged, the dorsal couple of 

 each side being so close to the mid-dorsal line, that only a slight 

 interval is left between the dorsalmost seta; of each side. 



Male pores on large papilhe on segment 18, the pore being- 

 just within the level of the second seta. 



Ovdduct opening on segment 14. 



Spermathecal pores, two, indicated by small white tumid 

 patches just dorsal to the level of the innermost setse between 

 segments 7 and 8, 8 and 9. 



Accessory copulatory structures. Two large circular patches 

 on segment 17, two elliptical patches on segments 18 and 19, 

 19 and 20. 



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



JSTephridiopores not visible. 



Alimentary canal. Gizzard in segment 5. No true calciferous

 pair of hearts in segment 12. Sub-intestinal vessel from which 

 in segments 10, 11 and 12 arise the hearts. 



Excretory system. Plectonephric with no large nephridia. 



Reproductive system. Testes, two pairs in segments 10 and 



11 with ciliated rosettes in the same segments. 

 Prostates small and flattened in segment 18. 



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



12 and the posterior of segment 9. 



Ovaries in segment 13 with oviducts opening into the same 

 segment.
