arising from septum W , and as contained in segment xii ; septum 

 H however does not exist as a definite septum {v. ant.), and 

 actually the seminal vesicles extend forwards as far as xi ; back- 

 wards tney reach H, which is bulged posteriorly by the vesicles so 

 as to reach the level of It. 



The vas deferens is conspicuous, on the body wall. The 

 prostates are large, tubular, and occupy xvii-xx. The duct is 

 narrow at first, but soon becomes stouter, more shining and more 

 muscular ; it is much coiled and of considerable length; its middle 

 part is the w-idest. 



Ovaries and funnels have the usual position. 



Each spermatheca has an elongated egg-shaped ampulla, the 

 end opposite the duct being the narrower. The duct is broad and 

 very short, so that the ampulla is almost sessile on the body-w^all 

 b}' an attachment at the middle of its under surface. There are 

 two diverticula ; one, the smaller, on the posterior and inner side of 

 the duct, with about six chambers ; the other on the outer side, 

 larger, with more numerous chambers. The chambers are only 

 slightly separated from each other externally, though they can be 

 distinguished by means of their contents. 



The penial setae (fig. 11) are 4 mm. in length, and 36/' in 

 breadth about the middle of the shaft. For the greater part of 

 their length the}^ are almost straight ; the terminal quarter of a 

 millimetre is bent at an angle of 120° ; and at the distance of only 

 •I mm. from the pointed tip there is a second, much sharper icink, 

 in such a way that this terminal portion is not in the same plane 

 as the rest of the seta. There are short transverse rows of very 

 finr: sculpturings near the free end.

 men, in bad condition. 



Length ;o mm.; breadth, maximum 3 mm.; colour light 

 olive green with a browner tinge anteriorly. Segments 185. 



Prostomium tanylobous, the longitudinal grooves traversing 

 the first segment dorsally being parallel to each other. 



The first dorsal pore is in furrow \l. 



The intersetal distances may be expressed as follows : — behind 

 the clitellum ab = \-%aa = f6c and approximately = cd; in front 

 of the clitellum ab = \aa = ibc and is slightly less than cd, — 

 i.e. the setae of the respective pairs are rather closer together, 

 rather more definitely paired, behind than in front of the 

 clitellum; dd = i circumference. 



The clitellum was indefinite. 



The male apertures, on segment xvii, are just external to the 

 line of setae b; they are represented by small papillae, on the 

 outer side of each of which is a slightly raised whitish horseshoe- 

 shaped ridge, partially surrounding the papilla, with the concavity 

 of the horseshoe directed intern all3^
