The female apertures were just indicated, situated in a pair 
of slight whitish thickenings immediately internal to setae a of 
segment xiv. 
The spermathecal apertures are three pairs, in furrows 6/7, 
7/8, and 8/g, situated well to the sides, about two-fifths of the 
circumference apart. The last is about opposite seta 7 or k of ix, 
the first opposite seta e of vi. 
Internal Anatomy.—Segment x is remarkably smooth on the 
inside; the bodywall is thinner here, and without nephridia. 
Septum 4/5 is thin, 5/6 somewhat thickened, 6/7 and 7/8 
moderately so; 8/9 and 9/10 are absent; 10/11, 11/12 and 12/13 
are moderately thickened, 13/14 and 14/15 slightly so. 
The blood-glands in segment vi are very conspicuous. The 
gizzard, ovoid and well developed, is in the middle of the space 
between septa 7/8 and 10/11. The oesophagus is bulged laterally 
behind the gizzard in the portion corresponding to segment x, and 
also in segments xi, xii and xiii. The intestine begins in xv. 
Intestinal diverticula, originating in xxvii, extend forwards through 
XXvi and xxv. 
The last heart is in segment xiii. 
The excretory system is micronephridial; there are the usual 
large tufts by the side of and behind the pharynx in segments v 
and vi. . 
The testes and funnels are contained in testis-sacs in segments 
x and xi, which probably communicate with their fellows across 
the middle line. 
The seminal vesicles are attached to the anterior walls of seg- 
ments xi and xii respectively ; they are lobed masses which do not 
meet dorsally over the intestine. 
The prostates (fig. 27), small glands in xvii and xviii, are cut 
up into numerous small lobules. The duct begins as a small soft 
tube which immediately swells and becomes firm and shining; it 
takes a much curved course, describing almost a complete circle, 
and increasing in diameter as it does so; at its broad ectal end it 
joins the outer margin of a soft white cushion on which it lies. 
The female organs have the usual situation. 
The laterally situated spermathecae (fig. 28) have a .charac- 
teristic form. The ampulla is relatively small, ovoid or pear- 
shaped. The duct is extremely stout, much longer than the am- 
pulla and almost straight. The diverticula are of two kinds. 
One is thin and finger-like, originating from the extreme base, or 
perhaps more properly from the bodywall close to the base of the 
duct, and approximately half the length of the duct. The second 
kind arises from the middle of the length of the duct; it consists 
of an irregular pear-shaped chamber presenting about five lobules, 
and a stalk which is half as stout as the main duct; the whole, 
stalk and chamber together, are nearly as long as the main am- 
pulla and duct above the point where the stalk of the diverticulum 
is attached. Lastly, in one out of the six spermathecae another 
diverticulum, of the second kind, but much smaller than the one
