Queensland Trematodes 
the oral sucker and measures 015-0T7 mm. in diameter. The oeso¬ 
phagus is twice as long as the pharynx and the intestinal diverticula 
extend almost to the posterior end of the body. In the posterior part 
they approach the ventral surface. The ventral sucker has a diameter 
of about 025 mm. 
The ovary is situated a little behind the middle of the body and 
measures 0'5 x 0 - 25 mm. It is a kidney-shaped organ with the hilum 
directed backwards. The two large testes lie immediately behind the 
ovary and are contiguous with each other. They extend across the 
whole breadth of the body. Their edges are crenated. 
The yolk glands extend from near the oral sucker along the whole 
length of the body. Iu the anterior part they fill up the whole breadth 
of the body, but in the testicular region they are restricted to narrow 
bands running along the ventral surface of the intestinal diverticula. 
They enter the pedicle of the adhesive disc and the ventral wall of the 
cup. The shell-gland complex lies between the testes and dorsal to 
them. Laui'er’s canal is present and the initial part of the uterus is 
filled with sperms. The uterus fills up the middle field of the whole 
posterior part of the body and contains numerous large eggs measuring 
0403-OT05 x 0'07-0'075 mm. The highly convoluted vesicula setninalis 
lies immediately behind the testes and opens on to a rather small genital 
papilla, which is enclosed in a bursa copulatrix of moderate size. The 
aperture of the bursa has a very slight dorsal inclination. 
This species does not correspond with any of the already known 
Australian Holostomids. It bears closest resemblance to the European 
Strigea gracilis, but differs from it in having yolk glands throughout 
the whole length of the body. 
Strigea flosculus n. sp. 
A few somewhat macerated specimens of this species were obtained 
from the intestine of a night-jar (Poclargus strigoides). They were not 
in a particularly good state for examination but sufficient details could 
be made out to show that they belong to a new species. The specimens 
are delicate and slender and measure 16-2 4 mm. in length. The 
anterior portion, which is shaped like a half-open rose bud, has a length 
of 0'55-0'7 mm. and its breadth is only slightly less (0’5-0’6 mm.). 
The posterior portion is almost fusiform, a little more than twice the 
length of the anterior portion, and about 0 - 4 mm. in maximum breadth. 
The two portions are separated by a marked constriction where the
