The funnels are barrel-shaped, and comparatively short—from one-and-a-half to two- 
and-a-half times as long as broad; they have an everted lip. The vasa deferentia are 
contained in segment xii., and do not extend beyond this; they are long, very narrow, 
and closely coiled tubes ; their length was roughly estimated at about fourteen times that 
of the funnel. The male aperture has associated with it a large spherical penial gland ; 
the apertures lie in an area where the surface epithelium is low and cubical, and sharply 
marked off from the high clitellar epithelium around (PI. I. fig. 6); each aperture is at the 
anterior part ofthe glandular mass, and is lined by a continuation of the surface epithelium, 
with characters unchanged ; the short tubular passage thus constituted passes obliquely 
backwards for a short distance from the surface, and after receiving the termination of 
the vas deferens on its upper wall, ends behind by dividing into about three short branches

(Pl. I. fig. 6). The penial gland is penetrated by the terminal part of the vas deferens, 
which enters the mass above, rather towards its lateral surface; the gland has a 
muscular capsule, and is composed of elongated cells, which are individually very 
distinct—much more so, for example, than in my specimens of L. subterraneus ; these 
cells are arranged so that they radiate around the vas deferens in its course through 
the mass, and around the branching invagination of the external surface of the body 
(see description of male aperture above). 
The spermathece, with their ducts, present a very characteristic appearance in the 
living animal, and may-be designated as ‘ trumpet-shaped’ (figs. 5a, 5b). The ampulla 
is small, subspherical, thin-walled in its equatorial region, but with much thicker walls 
over its dome, ze. around the situation of its communication with the cesophagus 
(Pl. I. fig. 7); the difference being due to the different height of its epithelial 
lining. The duct is thick-walled, much longer than the ampulla, produced from the
