The micronephridia are somewhat sparsely scattered. Be- 

 hind the cHtelhim they form a single transverse row in each seg- 

 ment, which consists on each side of a number set pretty close 

 together ventrally, with four more dorsally placed at considerable 

 intervals. 



Testes were not identified ; there are two pairs of funnels 

 apparently free, in segments x and xi. Seminal vesicles of moder- 

 ate size, lobed, are present in segment ix, and also in xii nr xii — 

 xiii, much lobed and larger than the anterior pair. 



The tubular prostates form a close coil occupying segments xvii 

 — .Kix or XX. The duct is also much coiled, of moderate length, 

 narrower than the glandular part, of the same diameter throughout, 

 and only slightlj- shining. 



The female organs have the usual situation. 



The spermathecae are one pair, in the anterior part of the 

 interval between septa 5/6 and 8/9. Each is an ovoid sac, sessile 

 on the parietes by a considerable portion of its under surface. 

 There is a single diverticulum on the outer, or posterior and outer, 

 side, of some size, also practically without stalk, slightly lobulated, 

 one-third as broad and half as high as the ampulla. 



The penial setae (fig. 11) are i'5 mm. long and 47/' thick at 

 the middle, with straight shaft and slightly curved tip tapering to 

 a blunt point. The ornamentation consists of a number of fine 

 triangular teeth on the curved tip. 



Remarks. — The present species comes near E. mohammedi, 

 from which however it is distinguished by the genital marking and 

 the character of the spermathecal diverticulum.

External Character. — Length 57 mm. Diameter max 175 

 mm. Segments 130; first segment very short. Colour pale, un- 

 pigmented, appearing grey from intestinal contents showing 

 through. 



Prostomiura proepilobous. 



Dorsal pores begin from furrow 11/12. 



The setae are paired. The ratios are nearly the same through 

 out the body; in the middle of the body ah=i/2aa or nearly 

 so=2/36c=3/4crf; further back be and cd maybe almost equal; 

 behind the clitellum ab = 2/5aa=i/2-4/7bc; dd=hali the circum- 

 ference in the middle of the body and behind, and -1/7 the 

 circumference in the anterior part of the body. 



The clitellum extends over xiii-|xvii (=4|-) ; it is yellowish 

 brown in colour, and constricted.
