Penial setae are missing. 



Spermathecae: The main pouch consists of a big irregularly pear-shaped 

 ampulla, narrowed distally, and a very short and very narrow muscular duct, almost 

 completely hidden in the body- wall. Into the narrowed distal end of the ampulla 

 opens a relatively large club-shaped diverticulum, which is somewhat shorter than 

 the ampulla, the greater proximal part of which represents a large, simple seminal 

 chamber.

 Present three mature specimens. 



External Characters. — Dimensions: I^ength 68 — 90 mm., greatest thickness 

 i^ — 2 mm., middle and hinder part of the body thinner, hardly i mm. thick ; number 

 of segments 120 — 140. 



Colour yellowish grey ; apparently without pigmentation. 



Head pro-epilobous. 



Setae rather tender, widely paired. At the anterior part of the body: the lateral 

 pairs only a little narrower, the ventral pairs distinctly narrower than the middle 

 lateral distances ; median ventral distance about | as large as the distance between 

 the setae of the ventral pairs ; median dorsal distance equalling about ^ of the cir- 

 cumference (at the anterior end aa=jah, ab = jbc, bc=^cd, dd=^u, or aa : ab: be: 

 cd : dd = 12 : 8 : 10 : g : 33). Towards the posterior end the ventral pairs widen some- 

 what, getting nearly if not quite as wide as the lateral pairs. The median dorsal 

 distance, on the other hand, diminishes (at the posterior end aa = i^ ab, ab=^, be =cd, 

 dd~\u,oraa:ab:bc:ed:dd = $:^:4:^:6). ^ 



First dorsal pore at the intersegmental furrow 13-14, if not somewhat more 

 forward. 



Clitellum ring-shaped, distinctly only on the three segments 14 — 16, more or less 

 indistinctly on the hinder part of segment 13 (or on the whole of the 13th segment 

 and on the anterior part of segment 17 ?). 



Male pores (fig. 4) in the Hnes of setae b on the i8th segment, on a com- 

 mon median ventral area. The male area has the figure of a trapezium rounded 

 at the angles and somewhat broader at the anterior part than behind. It occupies 

 the whole length of the 18th segment and surpasses laterally the lines of setae b. 

 The longitudinal borders are somewhat convex laterally, the transverse borders are 

 more or less concave. The whole organ has the appearance of a shield, having some- 

 what prominent sharply marked borders and a flat or even a slightly depressed interior
