Trematodes of North Queensland 
transverse. The anterior testis lies immediately behind, and contiguous 
with, the ovary, which it resembles in shape and size. The posterior 
testis is situated a short distance behind the first and a little nearer the 
mid line. The slender cirrus-pouch, which hes at the posterior end of 
the body, is about one-fifth of the body length. 
The yolk glands lie along the sides of the body immediately in 
front of the ovary. They consist of a single row of a dozen follicles 
on each side. The diameter of the follicles is about 0-03 mm. The 
most anteriorly situated follicle lies about TO mm. from the anterior 
end, and the length of the row of follicles is about 0-45 mm. There is 
a slight degree of asymmetry, the row of follicles on the right side 
being somewhat in advance of that on the left. The uterus is fairly 
voluminous and extends forwards to a point about 0-46 mm. from the 
anterior end of the body. It consists of a single ascending and descending 
loop. The latter does not cover the testes or ovary. The eggs are of 
fairly constant size, measuring 0-021 x 0-013 mm.
