Show 210 MR. F. E. BEDDARD ON EARTHWORMS [Jan. 14, separating the two setae of the dorsal couple is about two and a half times that separating the two setae of the ventral couple. The setae are all grouped on the ventral surface of the body, not extending far laterally. O n the xviith, xviiith, and xixth segments the ventral setae appear to drop out in the sexually mature worms. In an immature specimen the xviiith segment had a pair of ventral setae in the usual position, but small in size; on the xviith and xixth segments were a pair of very small and quite immature setae. I did not detect any of these on the opposite side of the body. Fig. 3. Benhamia indica. Nat. size. Dorsal pores were visible at the posterior end of the body, where the worm was less contracted. There are a series of genital papillce in the region of the spermathecae. A pair of large papillae lie upon segment ix.; through it protrude the setae of the segment, which differ from those of other segments of the body in being modified in structure. They are like those of many Geoscolecids in being rather longer than the ordinary setae, less curved in form, and in having the distal extremity ornamented with elegantly disposed semicircular ridges. Between this segment and the next, and again on the |
