Setae of the outer couples widely separated as in C. mediterreus. 
On the anterior annulus of xviii, on the middle and posterior 
annuli of the same segment, and on the anterior one of xix is a 
pair of papillae corresponding with the intervals between the setae 
of the inner couples ; the second pair of these apjiarently carry the 
( male pores, but they are not at all conspicuous : ventrad of each 
I papilla of the second pair is in some specimens a small papilla. 
! Oviduct and spermathecal pores as in G. mediterreus, but the 
former in a groove-like depi’ession. In none of the specimens is 
the ventral surface of some of segments vi-ix modified as in C. 
mediterreus. 
Dorsal pores commence between viii and ix. 
Nephridiopores as in G. mediterreus, the first three or four 
pairs opposite the fourth setse, then for two or three segments 
changing to the level of the third setae, then alternating between 
these two for some distance, and finally between the fourth and 
second ] on a given segment the two pores are not always at the 
same level on both sides of the body. 
Alimentary canal : gizzard in v ; four pairs of calciferous 
pouches in x-xiii, as in G. mediterreus, lying below and at the sides 
of the canal 3 large intestine commences in xvi. 
Genitalia : two pairs of ciliated )’osettes and testes in x and xi 3 
two pairs of vesiculae seminales in ix and XII3 prosoates in xviii-xix. 
Ova'ies and oviducts as usual 3 spermathecee three pairs, in 
vii-ix, each wiih usually two short cmca, one on each side and in 
f ont of the duct near its e.'.'it (nearer than in G. mediterreus), but 
either of these may be slightly bifid or even trifid just at the 
tip, or completely sub-divided into two or three, or in one case 
there was but a single broad flat cajcum 5- or 6 -lobed just at the 
tip. 
Nephridia as in G. mediterreus, that is to say, a pair of convo- 
luted tubules in each segment after the first one, those of alternate 
segments opening to the exterior opposite the setoe of the fourth 
or dorsal rows communicate with thin delicate vesicles just 
before opening to the exterior.
