funnel, which can be seen to fan out within the chamber so formed. The oviduct 

 apparently also opens partly into the receptaculum ovorum ; the short oviduct opens 

 on to the exterior in the usual way. The receptaculum ovorum was full of eggs. 

 I could find no ovary within the chamber into which the funnel of the oviduct opens, 

 and suspect that the ovarial tissue has been entirely transferred to the receptaculum 

 ovorum. In any case, the various sacs and ducts mentioned appeared to form a closed 

 system in which the ovary, if persistent elsewhere, was not included. I am not clear 

 how far this species agrees and disagrees with others of the genus. In three of the 

 four species described by Michaelsen, that naturalist figures a tube which encloses the 

 oviducal funnel at one end and opens at the other into the spermathecal sac. There 

 is no indication of any diverticula of the spermathecal sac which receives the 

 " Verbindungsschlauch," such as I find in Nemnanniella ruwenzorii. Nor could 

 I, as already mentioned, detect a special ovarian sac lodging the ovary and com- 

 municating with the rest of the egg-conducting apparatus, such as Michaelsen found. 

 It should be observed that this bifurcation of the spermathecal sac anteriorly to 

 receive the oviducts is exactly like the disposition of this sac in Polytoreutus. Its 

 presence in the species Neimianiella rimenzorii necessitates a revision of the generic 

 characters used by Michaelsen, who uses as a generic character the fact that 

 " Samentasche ganz unpaarig." This character alone therefore serves to discriminate 

 the present species from all of those described by Michaelsen. It may be thus 

 defined : — 



Neumanniella ruwenzoeii. 



Length 105 mm. ; breadth 3 mm. Distance hetiveen ventral setce about five times that 

 between dorsal setce. Some of the setce absent from clitelliim. Clitellum complete, 

 xiii./xviii. Male -pore single, median, upon xvii./xviii. Spermathecal pore single, 

 median, upon xiii./xiv. Spermiducal glands with loell-marJced narrow long duct, 

 each of which joins its fellow to open into fusiform muscular terminal chamber. 

 No penial setce. Spermathecal sac loith two diverticula, 'which receive oviducts at 

 extremities, and a small narrow muscular Bursa propulsoria.

I refer to a new species of the genus Eminoscolex a worm which is considerably 

 softened, but in which the more important characters are nevertheless plainly visible. 

 The completely paired condition of the male and female organs, coupled with the 

 ventral calciferous pouches in segments ix., x., xi. and the paired glands in 

 segment xiii., are decisive of its generic position. 



The worm measures rather more than 200 mm. in length by 4-5 mm. in width, and
