separating the two setis of the dorsal couple is about two and a 

 half times that separating the two setaj of the ventral couple. 

 The setse are all grouped on the ventral surface of the body, not 

 extending far laterally. On 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 

 setas 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.

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 

 spermathecse. 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 tlie body in being modiiied 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 ou the
