the oesophagus, though my preparations do not show the actual 
opening. ‘The duct is several times as long as the ampulla, and 
is bent once or twice in its course ; in diameter it is II-12p. 
I may add a few remarks on two of the above characters. 
The first is the penial body. The Enchytraeidae possess in general 
glandular structures surrounding the external end of the vas 
deferens, but differ among themselves in the disposition of the 
gland-cells ; in some cases there are a number of separate aggre- 
gates of these cells, opening on the surface of the body around the 
male aperture, while in other cases the whole of the gland-cells 
are compacted into a spherical, ovoid, or reniform penial body, 
surrounding the last part of the vas deferens. Eisen (6) proposes 
this distinction as a means of separating the Enchytraeidae 
into two subfamilies, the Lumbricillinae which have, and the 
Enchytraeinae which have not, a penial body. I have shown 
however (12) that the representative genera of the subfamilies, 
Lumbricillus and Enchytraeus, are connected by a number of forms 
which have a more or less intermediate position; and that in 
particular a penial body occurs in more than one species of 
Enchytraeus. It is interesting to find that this is the case in 
the present species also. 
The second point is the condition of the seminal funnel. Its 
general form in the Enchytraeidae is described by the word ‘ bar- 
rel-shaped,’ and this form is occasioned by the excessive elonga- 
tion of the cells composing the first part of the duct ; at the same 
time the cells become clear and stain only slightly, due presum- 
ably to the formation within them of a mucous substance. In 
the present species the funnel is small, and the change in the cells 
comparatively slight ; the condition is therefore intermediate be- 
tween that usual in other families and that which is characteristic 
of the Enchytraeidae.
