Trematodes 
The ovary lies behind and to the left side of the left testis. It is 
sub-globular and slightly smaller than the testes. Immediately behind 
it lie the digitiform yolk glands of which only five, of the usual seven, 
portions could be defined. They are short and irregular. The uterus, 
which was very poorly developed, formed a series of straggling convolu¬ 
tions behind the genital glands. The eggs which were of the small 
Hemiurid type were not measured. 
The obvious defects in the foregoing description are to be accounted 
for by the fact that my examination of the specimen was not complete 
at the time of my departure from Townsville. 
Genus DOLICHOPERA Nicoll. 
Dolichopera macalpini Nicoll. 
(Plate VIII, fig. 4.) 
A description of this species which was obtained from the tiger- 
snake and copperhead snake in Victoria and New South Wales has 
already been published in Parasitology (vol. x. 2). A figure of the species 
is reproduced on Plate VIII.
