Seta', from U-11 on each side in front of the clitellum ; 

 behind this, 10-12 eacli side. Dorsally and ventrall}' there 

 is a median space free of setfe. 



Male pores on segment 18 on papillie, on a level with the 

 second seta on each side. 



Oviduct pores on segment 14 anterior to, and very 

 slightly ventral of, the level of the innermost setfe. 



Spermathecal pores, five pairs, betv/een segments 4? and 5, 

 5 and G, G and 7, 7 and 8, 8 and '.), at the level ot the second 

 setfie of each side. 



Accessory copulatory structures. A pair of elliptical 

 tumid patches between segments IG and 17, at the level of 

 the interval between the two inner setse of each side. A 

 pair at the same level on the anterior part of segment 18^ 

 and anocher between segments 17 and 18, at the level of the 

 interval between the second and third setse of each side. A 

 swollen tumid ridge occupies the posterior part ventrally of 

 .segment 18, and the anterior of segment 19, extending 

 outwards as far as the level of the third seta of each side. 

 A ridge on the posterior part of segment 1 9, and anterior of 

 segment 20, extending outwards as far as the level- of the 

 second seta of each side. These structures, and especially 

 the two on each side immediately in front of the male 

 openings, are very characteristic. 



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



Alimentary- canal. Gizzard in segment 5. Ino true 

 calcifeious glands present, but vascular swellings in 

 segments 12-15 ; those in 14 and 15 being especially large. 

 Large intestine commencing in segment 17. 



Circulatory system. Dorsal vessel single ; last heart in 

 segment ]'2. Those in segments 10, 11, 12 large; those in 

 segments 7, 8, 9 small. Supi'a-intestinal vessel in segments 

 9-12. 



Excretory system. Meganephric. 



Reproductive system. Testes, two pairs in segments 

 10 and 11, into which open the rosettes. 



Prostates tubular, coiled, extending through segments 

 17, 18, and 19. 



Sperm sacs, two pairs attached respectively to the anterior 

 wall of segment 12, and the posterior of segment 9. 



Ovaries in segment 13, the oviducts opening into the same 

 seo-ment.
