The male apertures are on prominent oval papillae, with their 
long axis transversely disposed in furrow 10/11. ‘The papillae ob- 
literate the furrow where they lie, and extend in a transverse direc- 
tion inwards to the line of setae 6, outwards not much more than 
halfway from 6 toc; in a longitudinal direction they take up half 
the length of segment xi, and nearly half of x. The apertures 
themselves lie between the lines } and c, but nearer to D. 
The female apertures were not seen. 
The spermathecal apertures are in furrow 7/8, between 0 and c, 
but nearer to c. 
There is a pair of genital papillae anteriorly on segment vii. 
These are flat-topped and circular, with their anterior margin 
touching furrow 6/7, they are rather internal to the spermathecal 
apertures, and therefore their centres are about midway between 
band c. 
Internal Anatomy.—Septa 5/6, 6/7, 7/8, 8/9 are all considerably 
thickened, 9/10 is very thin, and so are the rest. Septa 10/11 and 
11/12, in fact, seemed to be defective ; no ovarian chamber had 
been formed and these septa were not recognizable at all dorsal to 
the gut. But they seem to be present in the ventral part of their 
segments, and a fringe on one of them perhaps represents the 
ovary. 
The gizzards are four in number, in segments xii-xv, that in 
xii being smaller than the rest. These gizzards are bands of 
muscular gut which are separated from each other by thinner and 
quite soft bands of gut-wall; the bands of one kind are about 
equal in breadth (antero-posteriorly) to those of the other kind. 
The last heart is in segment ix. 2 
The testisssacs are large, subovoid in shape, attached to 
septum 9/10, but wholly dependent into segment x, being attached 
indeed only by a slender neck. ‘The sac of the right side was much 
posterior to that of the left, being displaced backwards by a bulging 
of the alimentary tube on that side. ‘The vas deferens runs from 
the lower and anterior end of the testis-sac downwards, and joins 
the anterior end of the prostate a little to the inner side of its 
longitudinal axis; its course is relatively short, since though wavy 
it is otherwise straight. 
The prostate of the right side, in the single specimen which 
came under examination, was vertically flattened, with a generally 
circular outline and small marginal lobulation. On the left side it 
was much more elongated, and bent on itself with the convexity 
looking outwards; the ental (remote from external aperture) end 
was posterior, thicker than the ectal portion, and markedly lobu- 
lated ,—more so than the ectal part of the gland ; the vas deferens 
here passes from the anterior end along the outer border to end at 
the middle of the outer surface (fig. 4). 
All that can be said of the ovaries and ovarian chamber has 
been noted when describing the septa. 
The spermathecae, in segment vii, are large ovoid sacs full of 
white flocculent matter, which touch each other in the middle line.
