groove between xiii and xiv is not qtiite effaced, while just the 
anterior margin of xviii is modified), complete all round except 
for a dumb-bell-shafied genital papilla on the hinder portion of it 
situated between xn and xvir but mostly on the latter, consisting 
of two small elliptical depressions with tumid margins corres- 
ponding with the intervals between the setse of the inner couples 
but extending each way a little beyond them, connected by a sort 
of ridge, the intervening ventral portion between the depressions, 
except the posterior annulus of xni, becoming tumid. The 
ventral surface of xviil forms a shallow depression with raised or 
tumid margins (or it may be more or less dnmb-beU-shaped like 
that which precedes it), extending outwards on each side nearly 
to the second row of setae, on which are situated the male pores 
just dorsaid of the first row of setae. In three of the specimens 
between xxi and xxil and occupying the posterior annulus of the 
former, and the anterior and middle ones of the latter, is an 
elliptical elevation, its central portion depressed but not extending 
outwards on each side as far ais the first seta ; a fourth has an 
additional and similar one between xxii and xxiii ; while the 
fifth hais them between xx and xxi, and xxi and xxii. 0%fiduct 
pores on xiv, rather far apart, in front and just ventrad of the 
inner rows of setae, usually situated towards the ends of a 
shallow transverse slit-like depression ; spermathecal pores two 
pairs, on the anterior margins of viii and ix, about opposite the 
first setae. 
First dorsal pore after about xi. Xephridiopores invisible. 
Alimentary canal : gizzard in segment v ; in x to xiii four pairs 
of calciferous pouches, kidney-shap>ed and stalked, and overlying 
the intestine as in C. saccarim, not underlying it as in Beddard’s 
sp>ecie8, and in C. carudicaUxtus ; the large intestine commences 
in XVI. 
Genitalia ; two pairs testes and ciliated rosettes in x and xi ; 
two pairs vesiculse seminales in xi and xii ; prostates in xvii-xxii 
or XXIII, the genital ducts long and coiled (the vasa deferentia not 
visible). Spermathecje two pairs, in viii and ix, the stalk (duct)
