3§8 MR. r. E. BBDDAED ON" EAE'tHWORMS [A-pl'. 16, 



lid». Ill any case I have ascertained that in several genera of 

 the Pareudriiine division the arrangement of the funnels with 

 reference to the testes is carried out on the normal Oligochsetous 

 plan. However, in Stuhhnmmia, with which I deal here, the 

 funnels bend round and open into a funnel which faces the hinder 

 end of the body precisely as they do in Teleudrilus and Hypciio- 

 drilus. Moreover, a slight swelling of the sperm-duct just after 

 it escapes from the funnel suggests a rudiment of the large 

 chamber into which the sperm-duct of such genera as Eiidrilus, 

 Teleudrilus, and IJyperiodrilus expands in the same region. This 

 fact brings closer together the two divisions of the Eudrilidse. 

 It may be also pointed out that iu being thus turned round the 

 sperm-duct funnels correspond more accurately with the .oviducal 

 funnels than they do in some worms. 



(5) Contributions to our Knoiuledge of the Genus Gordiodrilus. 



This geuus was founded ten years ago by myself \ and five 

 species of it were described, to which a sixth from East Africa was 

 subsequently added ". Since that period the genus has not received 

 attention at the hands of any naturalist, though the genus as such 

 has been universally^ accepted. In the present communication I 

 have some further facts to add to what is known about Oordio- 

 drihis, and the material upon which these observations were made 

 necessitates the creation of one new species. This material was 

 collected in the neighbourhood of Lagos on the west coast of 

 Africa by the late Mr. Alvan Millson. I have examined three 

 examples of Gordiodrilus, which seem to be referable to two 

 distinct species. A fourth worm, though, so far as could be judged, 

 clearly a member of the same genus, was not sufficiently mature 

 to be placed with certainty in its proper species. Indeed none of 

 the species appeared to be quite fully mature. The neai-est 

 approach to complete sexual maturity was shown by the one 

 individual which I consider to represent a neA^' species, for 

 which I propose the name of 



GOBDIODRILUS PAPILLATUS, n. Sp. 



Of this distinctly new form of Gordiodrilus (text-fig. 88, p. 359) I 

 have had, as already stated, but a single example, nearly if not fully 

 mature. It is a long slender worm like all the members of the 

 genus, and its marked tenuity is more suggestive of Gordiodrilus 

 tenuis than of any other species. It has, moreover, as will be seen 

 in the sequel, other points of likeness to that, the most anomalous 

 species of the genus. The transjmrency of the body-walls is 

 apparent even in the spirit-preserved individual, and the sperm- 

 sacs show through the delicate body-wall quite plainly. This is 

 also a feature of G. tenuis.
