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 spermathecze occupying segments 8, 
9,10, and 11. The oviducal pores are two, upon segments 15 and 
16. The male generative pores are uponsegment19. The clitellum 
extends from segments 15-18 inclusive (fig. 6). 
(11) There are three pairs of spermathecz 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, but the 18th and 19th segments 
were ouly 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 spermathece, 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 bady. 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:—
