Distal ends of sperm-ducts with a big muscular coat, embracing the distal 

 ends of the prostates laterally and opening from behind into the same pores with the 

 latter. 



There are strong transverse muscles in the vicinity of the male pores. 



Penial setae (figs. 52, 53) robust, about 2 mm. long, proximally about 95 /, thick, 

 tapering very little towards the distal end, being still 80 m thick at the end of the 

 distal fourth, slightly bent in the proximal half, more strongly bent distally. The 

 distal end is simple, often irregular, apparently corrugated, fibrous. The distal half of 

 the seta shows a characteristic ornamentation, consisting of very densely crowded^ 

 irregular, transverse rows of fine teeth, . the rows probably embracing the whole 

 seta. This superficial ornamentation is not easy to be detected on account of the 

 rough internal structure of the seta, consisting of a combination of annulose and 

 fibrous structure ; these fibres diverge from the axis of the seta obliquely towards 

 the periphery and the distal end. By this rough structure the appearance of the 

 seta varies very much if the focus and the direction of the light be changed during 

 the microscopical examination. I suppose that the penial setae of E. orientalis 

 (BEDD.)^ may have a similar structure (and ornamentation, which was probably 

 overlooked ?). 



Spermathecae (fig. 51) : Main pouch with an irregular sac-l'ke ampulla 

 and a rather short and narrow muscular duct which arises in about the middle of the 

 long side of the ampulla. Into the duct open from opposite sides two diverticula which 

 may be either simple or compound. In the latter case they consist of two more or 

 less widely separated seminal chambers which are sometimes united only at their 

 bases. The diverticula are somewhat longer than thick, relatively small, and in situ 

 totally hidden beneath the ampulla.

Present one mature specimen, somewhat mutilated behind the clitellum, and some 

 immature or half-mature ones. Owing to their immaturity it is somewhat uncertain 

 whether the latter belong to this species. 



External Characters. — Dimensions of the mature specimen : Ivength9omm., 

 thickness 3—4 mm., number of segments ca. 240. 



Colour in general yellowish grey, at the anterior parts of the body with violet- 

 grey tints. 



Head tanylobous, first segment very long.
