DR. J. STEPHENSON ON THE OLIGOCH^TA OF THE 



substantial, with a number of much elongated nuclei in its wall. 

 The substance of the lobes consists proximally of a mass of cells 

 only ; further from their attachment they dissolve into sperm- 

 morulre, still contained within the sacs. There is a large vacancy 

 in septum 10/11 ; as already said, the lobes of the testes extend 

 into both segments. 



The funnel is short and stout — about twice, or at any rate not 

 more than three times, as long as wide. In a specimen in which 

 the funnels were isolated by dilaceration they were not more 

 than 1^ times as long as wide. The vas deferens is long and 

 much coiled, but in the dilacerated specimen not so tightl}" as 

 in the next species; it is confined to segm. xii. ; in diameter it 

 measures 10-12 /i. 



The penial body is compact, subspherical in shape, in diameter 

 130-160 fi, of the usual lumbricilline type, with a strong muscular 

 capsule. It causes a slight projection on the surface.

Spermatlicca of Lwmhricilhis mgialites isolated by dilaceration. Arnp., ampulla; 

 coag., coagulum in ampulla ; d., duct ; gl,, mass of gland-cells. 



The ovaries are in segm. xii. ; loose ova are present in xii. and 

 also in xiii. There is no ovisac. The female funnels are merelj^ 

 backward bulgings of the septum. The oviducts axe not as yet 

 patent. 



The spermathecal ampulla is smoothly ovoid, 90-100 /i in 

 diameter, and communicates with tlie oesophagus by a rather 

 narrow neck. The duct is straight and as long as the ampulla. 

 A large mass of gland-cells surrounds the duct, and takes up all 

 the space between the parietes and the ampulla — even surround- 

 ing the basal half of the ampulla ; the upper margin of this mass 

 of gland-cells is slightly lobed (text-fig. 3). 



Copulatory glands (" ventral glands ") are present in segments
