ptihertatis. This is confirmed by the fact that in the second im- 

 mature example without a cliteUum the tubercula pubertatis were 

 nevertheless quite plain, though apparently occupying a segment 

 less.

The copulatory papillce (text-fig. 86) with their setse are very 

 obvious and very numerous in this species. In both specimens 

 there are two series of these papillfe, one anterior to the clitellum 

 and one on some of the posterior segments of the clitellum. In 

 the fully mature individual with the completely developed clitellum 

 there is a single pair of these structures on segment xi., a papilla 

 of the pair being situated a little to the dorsal side of each 

 ventral pair of setee. These (the ventral) setse are also present on 

 the xith segment. These anterior papillfe are considerably larger 

 than those of the posterior series. The latter are in all five pairs 

 situated on segments xxiii.-xxvii. inclusive, thus immediately 

 continuing on the tubercula pubertatis. In the immature indi- 

 vidual there were the same papillae upon the xith segment ; but in
