Male pores on two small papillas corresponding with the interval 
between the first and second setfe on each side, the pores them- 
selves a little dorsad of first seta; the papillae frequently connected 
by an intermediate ridge, while contiguous to and immediately 
dorsad of each of them is a more or less developed eminence 
extending outwards to the third or fourth setae, and from 
before backwards more or less completely across segment xviii. 
Oviduct pores just in front of the ventral interval devoid of setae 
on XIV, rather close together ; spermathecal pores two pairs [in 
one case three pairs, and in another four pores on one side and 
three on the other], between vii and viii, and viii and ix [when 
more in front of these] in line with or just dorsad of the first setae 
on each side. Accessory copulatory structures comprise modifica- 
tions of the ventral surface of segments vii-x, xvii, and xix-xxiii ; 
on each of vii-x a pair of sub-circular swellings, one just on each 
side of the median line, extending outwards to the third or fourth 
setae, and occupying about the anterior two-thirds of the width 
(from before backwards) of the segment, a pore-like depression in 
each, opposite and in front of the interval between the first and 
second setae ; on the others usually a transverse linear fossa with 
raised rims in front of the interval devoid of setae, or simply an 
eminence, and reaching outwards on each side to about the second 
setae, in one case the posterior four being situated in raised quadri- 
lateral areas grooved in the median longitudinal line ; in most of 
the specimens these structures are represented only by ill-defined 
swollen surfaces, but indications of them in some shape or other 
are very constant. 
Nepridiopores invisible. Dorsal pores commence after segment 
iv or V. 
Alimentary canal; a white glandular mass commencing on the 
posterior half of the pharyn.x and extending back to about segment 
vn. overlying and obscuring the small gizzard in v, is very notice- 
able ; three pairs of calciferous pouches, in x-xii ; in most of the 
S|>ecimens dissected the large intestine appeared to begin about 
xxv, but this was, I think, merely accidental.
