very numerous and closely set villous processes ; the swelling and 
the processes are both less marked in xiv, but there seems to be no 
definite posterior limit to this portion of the canal. The intestine 
begins in xix; the typhlosole in the middle of the body is low, and 
presents a number of parallel transverse folds. 
The last heart is in xiii. 
The condition of the nephridia is interesting. On the body- 
wall, in each of the most anterior segments, are a number of tufts, 
one on each side, each component of a tuft being a fairly stout 
coiled micronephridial tube; there are about half a dozen such 
tubes in each tuft, and all these loops or coils converge and are 
united at the base of the tuft into what may be compared to the 
main trunk of a bush. In segment vi, on the right side, the tuft 
is large, and two loops are considerably longer than the others; in 
vii the five loops or coils are of various sizes, from long to short; 
in viii and ix two are much longer than the rest; but this is not 
so noticeable in the immediately succeeding segments. In xii, of 
three coils, two are long and one short; in xiii there is a diminishing 
series of four. After this there is constantly one long loop stretch- 
ing outwards on the bodywall. In addition, there are a large 
number of very minute micronephridia scattered further out on the 
bodywall; but not in the most anterior segments,—that is not in 
front of about segment x. 
In the middle region of the body there is a large meganephri- 
dium and a number of small micronephridia on each side in each 
segment. ‘The latter form a transverse line about the middle of 
each segment. Each meganephridium (fig. 9) begins as a cluster of 
funnels, about half a dozen in number, underneath the intestine ; 
they are situated just in front of the posterior septum of the seg- 
ment. The tubes leading from the funnels pierce the septum in a 
bunch, and become continuous with the main portion of the nephrt- 
dium, which is situated as usual in the segment behind the funnels. 
This portion presents, besides a mass of coiled tubes, the course of 
which I did not minutely investigate, two considerable loops, 
which stretch outwards on the bodywall; one stout and conspi- 
cuous, and another, which at first escaped my observation, incon- 
spicuous and very thin, but very long; the parallel limbs of which 
this longer loop is constituted extend very far out on the bodywall, 
almost to the mid-dorsal line. 
The funnels, examined microscopically, show a deeply inden- 
ted lip on one side of the margin; cilia were seen in various parts 
of the tube, but I could not distinguish any on the funnel ; a mass 
of disintegrating cells was seen to surround the apertures of the 
funnels. 
Testes and funnels are free in segments x and xi. 
Vesiculae seminales are present in segments xi and xii. In xi 
there is a single sac, attached to the anterior septum of the seg- 
ment, large, flocculent looking and not lobed, extending quite 
undivided across the middle line. In xii the sac is small, similar 
in position, and also continuous across the middle line.
