Show 310 MR. F. E. BEDDARD ON N E W OR [May 1 8, 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 spermathecae occupying segments 8, 9, 10, and 11. 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). (II) There are three pairs of spermathecae 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 tbe 1 Sth and 19th 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. Figs. 3, 4, 6. Varieties of Perionyx excavatus. Fig. 5. Normal individual. (14) There were two pairs of spermathecae, 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 1 6 ; the male pores upon segment 18. These different varieties may be tabulated as follows: - |
