Spermathecce (p1. xiv, figs. 3 and 4). — The long muscular duct is 

 covered exteriorly by parallel muscular sti'ands. Viewed in cross, 

 section it is seen that the strands are separated one from the other. 

 The narrow duct of the ampulla is continued parallel to the intestine 

 as far as the septum VII/VIII, where it enters the intestine. There 

 are three large basal glands which enter the somewhat enlarged duct. 



Sper7n-ftinnel and duct. — The funnel is about twelve times as 

 wide as the duct. The latter is confined to somite XII.

Nephridia (fig. 60). — The anteseptal is very broad and almost as 

 long as the main body of the postseptal. The duct is either strongly 

 coiled in the anteseptal or forms a network of anastomosing ductules. 

 The nephridia are somewhat variable in shape. The figures are all 

 from nephridia posterior to clitellum. 



Dorsal pores. — There is considerable doubt as to the presence of 

 the dorsal pores. Close in front of the septa of the four anterior 

 somites there is a structure closely resembling the cells which gener- 

 ally surround dorsal pores, but I have been unable to see the respective 

 openings. Hence the question mark in the definition. 



Papillce. — There are two exterior papillae anterior to the male pores, 

 one ventral and situated somewhat to one side of the median line in 

 XI, the other in somite VI also slightly on one side of the median 

 ventral line. My longitudinal sections did not show their structure. 



Seicc. — The setae are slightly sigmoid. The venti^al sette diminish 

 in size toward the ventral Interval, while the lateral setae diminish in 

 size toward the dorsal interval.
