Dimensions: lycngth 112 mm., nmnber of segments 151. In all other external 

 and in most of the internal characters my specimen agrees with the description given 

 by BEDDARD. The following remarks may be made regarding this species. 



Internal Anatomy.— Septa 6-7 and 7-8 are missing, 4-5, 5-6, 9-10 and lo-ii 

 very strong, 8-9 moderately strong. 



Alimentary tract: A large gizzard between septa 5-6 and 8-9. The 

 calciferous glands seem to occupy not only the 12th but also the nth segment. The 

 glands are externally not set off from the oesophagus, but internally their lumen is 

 somewhat separated from the main lumen of the œsophagus. 



Male organs: I can confirm the existence of two pairs of sperm-sacs in the 9th 

 and 12th segments, the former smaller, depending from septum 9-10. BKDDARD's 

 type specimens showed a curious disharmony, being holoandric in relation to the 

 sperm-sac (and, as may be inferred from these, in relation to the testes), metandric 

 in relation to the sperm-duct-funnels, which are seen in the nth segment. My 

 specimen, on the contrary, seemed to be formed more normally, being apparently 

 holoandric throughout. There are surely sperm-duct-funnels in the loth segment as 

 well as in the nth, but I am not able to affirm that they are separated from one 

 another. There might be a single sperm-duct-funnel at each side, divided by septum 

 lo-ii, the divisions depending into both segments. That would be, however, a very 

 curious arrangement. I believe the view that E. incommodus is normally a holoandric 

 species, as are some other species of this genus, a justifiable one.

(Plate xiv, fig. 37.) 

 E. n., MICHABLSEN, in Mt. Mus. Hamburg, xxiv, p. 176, f. 20. 

 Examined seven mature specimens. 



External Characters. — Dimensions: I^ength no — 140 mm., thickness about 

 3| mm. at the hinder end, to 6 mm. at the clitellar region; number of segments 

 150 — 180. 



Colour greyish. 



Head more or less distinctly tanylobous. Prostomium small, more or less 

 retracted; dorsal hinder appendix at the anterior end very small, increasing backwards ; 

 lateral borders of it not always distinctly different from the densely crowded longitu- 

 dinal furrows of the ist segment. 



Segments 4 and 5 divided by one transverse furrow, 6 — 8 by two, 9 by four, 10 by 

 two. 



Setae moderately large, especially the ventral ones of the anteclitellar region, 

 widely paired or separated, all at the ventral part of the body, the median dorsal dis- 

 tance being distinctly larger than half the circumference of the body {dd = ^-lu). 

 Median ventral distance a little greater than the median laterals, these subequal to the
