covered with a thin ornamented bark which had fallen ofï from the extreme 

 distal end. The ornamentation of this bark-like covering on the concave under 

 side of the distal part of the seta consists of many crowded, relatively large, 

 oval, blister-like protuberances which partly end in a fine, curved thorn or hook, 

 bent against the surface of the seta. I suppose that all these blister-like protuber- 

 ances normally end in such a hook, but that in most of them this hook is incon- 

 spicuous (being pressed against the surface of the seta) or worn off. In most of 

 the penial setae the distal end has the appearance of being much worn off or mutilated ; 

 and in these the characteristic shape and ornamentation is not easy, if at all, to be 

 detected. Beneath the flattened distal end the seta bears all round another orna- 

 mentation which consists of densely crowded serrulate bent transverse ridges curving 

 outward. This ornamentation gives to the surface of the seta the appearance of a 

 scaled fish-skin. Towards the proximal part of the seta the ornamentation gets sparser 

 and is reduced to irregularly distributed small groups of teeth. 



Spermathecse (fig. 41): Main pouch with an irregular, oblique sac-like 

 ampulla and a thick short duct which does not arise from the narrow end of the am- 

 pulla, but from the under side of the ampulla somewhat behind the narrow end which 

 surpasses the intersegmental furrow 7-8 towards the anterior end of the worm. At each 

 side of the duct of the main pouch opens a diverticulum which consists of a rather 

 great number of nearly globular seminal chambers. The seminal chambers are united 

 and form more or less prominent protuberances on the outer surface of the diver- 

 ticulum which is sometimes divided by deep incisions into two parts with a common 

 short and narrow stalk.

(Plate xiv, figs. 51— 53-) 



E. s., MICHAELSEN, in Mt. Mus. Hamburg, xxiv, p. 186, f. 29. 

 Present three mature specimens. 



External Characters, — Dimensions : Length 140 — 180 mm., thickness from 

 3 — 4 mm. at the posterior end, to 5 mm. at the anterior part of the body, number of 

 segments ca. 290. 



Colour greyish with violet tints at the anterior part of the body. 



Head indistinctly epilobous (?). 



Setae all on the ventral side of the body, the median dorsal distance being larger 

 than half the circumference [dd >\ u). Setae paired, but not strictly : at the anterior 

 part of the body closely: aa : ah : be : cd=^ : 2 : 3 : 2; beh'nd the clitellum the 

 distance ab becomes smaller : aa : ab : be : ci = 3 : i : 3 : 2; at the posterior end cd 

 grows nearly as large as &c : aa : ab : be : cd =2^ : i : 2 : if ; but at the posterior 

 end the arrangement of the setae seems to be somewhat irregular. 



First dorsal pore in the intersegmental furrow 11-12. 



Clitellum ring-shaped, occupying the segments | of 13—17 ( =4i)-
