segments 7, 8, and 9. The female pore is single and upon segment 

 14 ; the male pores are upon segment 17. 



(10) There are four pairs of spermathecse occupying segments 8, 

 9, 10, and 1 ) . The oviducal pores are two, upon segments 15 and 

 16. The male generative pores are upon segment 19. The clitellum 

 extends from segments 15-18 inclusive (fig. 6). 



(11) There are three pairs of spermathecee in segments 6, 7> and 8. 

 The female generative pores are upon segments 13 and 14 ; the 

 male generative pores are upon segment 16. 



(12) Of this variety I noted two specimens. The female and the 

 male pores were perfectly normal, hut the 18th and 19t]i segments 

 were only separated from each other on the right side of the body ; 

 on the left side they were fused. 



(13) There were also two specimens of this variety. The female 

 pores were upon segments 14 and 15 ; the male pores occupied the 

 normal position upon segment 18.

(14) There were two pairs of spermathecEe, occupying the ordinary 

 position in segments 8 and 9. The female generative pores were 

 upon segments 15 and 17; the male pores upon segment 21. 

 Segments 11, 12, and 18, 19 were only divided from each other on 

 the left side of the body. Viewed from the right side, the female pores 

 were upon segments 14 and 15, the male pores upon segment 18. 



(15) The female generative pores were upon segments 15 and 16 ; 

 the male pores upon segment 18. 



These different varieties may be tabulated as follows: —
