(Plate xiv, figs. 38. 39-) 

 E. p., MICHAELSEN, in Mt. Mus. Hamburg, xxiv, p. 178, f. 23. 

 Present one specimen. 



External Characters. — Dimensions: I^ength 195 mm., thickness 3I — 5 mm., 

 number of segments ca. 220. 



Colour violet-brown dorsally with a darker median dorsal stripe, greyish 

 laterally and ventrally. 



Head tanylobous; borders of the dorsal hinder appendix of prostomium parallel 

 to each other. 



Setae all at the ventral side of the body, the medial dorsal distance being larger 

 than half the circumference {dd>^u). Setae paired, but not strictly, in general aa: 

 ab : be : cd=^ : 2 : 3 : 2 — -2^ ; the setae of the lateral pairs are only at the posterior 

 end of the body further remote one from the other than those of the ventral pairs. 



Dorsal pores present, but inconspicuous, seen only in the middle parts of the 

 body. 



Clitellum occupying the segments ^ of 13—17 ( =4^), ring-shaped, but ventrally 

 less developed, totally missing ventrally at the 17th segment. 



Male pores in deep hollows on the 17th segment in about the lines of setae b, 

 surrounded by tumid parts of the body -wall. 



Spermathecal pores one pair on the intersegmental furrow 7-8, distinct 

 transverse slits between the lines of setae b and c, nearly reaching the lines of setae b, 

 accompanied by tumid patches before and behind them. 



Copulatory organs paired transversely oval areas in the 

 lines of the ventral pairs of setae, somewhat transgressing them in 

 both directions, seven pairs, on the intersegmental furrows 15-16, 

 16-17 and 18-19 — 22-23. 



Internal Anatomy Septa 4-5, 5-6 and 8-9 — lo-ii very 



strong, 6-7 and 7-8 missing. 



Alimentary tract: A big gizzard between septa 5-6 and 

 8-9. CEsophagus swollen in the 12th segment, showing externally 

 many densely crowded lateral transverse stripes indicating the- 

 lamellar structure of the calciferous glands in the interior of the oeso- 

 phagus. Intestine beginning in the 15th segment, laterally saccu- 

 lated in the anterior part, with a typhlosole further back. Typhlo- 

 sole in transverse section triangular, with a broad base and a sharp 

 edge ; the margins of the base are incised laterally, the incisions of 

 both sides alternating and thereby giving to the base the form of 

 a zigzag line pressed together longitudinally.
