244 Memoirs of the Indian Museum. [Vol. VII, 



Michaelsen does not mention the clitellum of bengalensis, and it was presumably 

 absent. This I take to be a sign of immaturity. The same may be said of the 

 absence of the genital markings. 



The original account of bengalensis has "testes and sperm-duct-funnels free (?) "; 

 my note on the specimens which I did not doubt, at the time, were bengalensis runs 

 "I think sperm-sacs; the membrane is certainly very thin, but to the best of my 

 observation it exists." E. rualtoni has a common sperm-sac; so that there is pro- 

 bably no difference here. 



One chief difference is that the penial setae of ivaltoni are beset with minute 

 spines near the tip, while those of bengalensis are smooth (the shape is much the 

 same). I have already noted (9) that I could not identif}^ distinct spines even with 

 the oil immersion lens in some specimens of waltoni ; and in the present series, among 

 those which are undoubtedly ivaltoni, I have twice found the spines absent from the 

 spoonshaped tip, though a few were seen further up the shaft. 



Lastly the spermathecal diverticula are said to be on opposite sides of the duct 

 in bengalensis, side by side in waltoni ; in some of the present series of ivaltoni how- 

 ever I have found them opposite each other.

Same place, date, and collector. Under bark. Three specimens, immature. W x -p. 



External Characters: — Length 100 mm.; maximum diameter 3*5 mm. Colour 

 light grey, unpigmented; no difference between dorsal and ventral surfaces. Seg- 

 ments 171; segments long in front of, short behind the male apertures. Segments 

 v and vi biannular or indistinctly triannular, vii triannular, viii and ix triannular 

 with other secondary furrows also, x triannular, xi indistinctly so. 



Prostomium small, tanylobous, tongue broader behind than in front. 



Dorsal pores from furrow 11/12. 



Setae are scarcely visible on segments ix and x, while they are enlarged on iii_ 

 vi. The intervals may be expressed thus : — Anteriorly ab=^aa=\m\i bc=\ed; behind 

 the clitellum ab=\aa = '\bc-=\cd; in the middle of the body ab=\aa=\\a\î bc=\cd-, 

 dd is nearly equal to two- thirds of the circumference. 



The clitellum is very slightly marked ; all that is to be seen is some thickening 

 ventrally on segments xv to xvii. 



The male pores, on segment xvii, are in a pair of narrow transverse depressions 

 which extend over an interval greater than ab, the limits of the depressions being 

 inside the line a and outside b ; penial setae, marking the site of the aperture, pro- 

 trude in the line b. 



The female apertures were not visible. 



The spermathecal apertures are in furrow 7/8, in the line b.
