In the present work, D. contractus was identical in its morphological aspects<br />
to Looss (1902) specimens except for minor differences in certain<br />
measurements. In the redescription recorded by Fares and Maillard (1974),<br />
the excretory vesicle was y-shaped while in the present material it was<br />
spherical, a feature which has been recorded by Looss (1902). Al-Bassel<br />
(1987) recorded the parasite but his measurements were smaller (total body<br />
length 0.49-0.65) than that recorded in the present work (0.738-0.838)<br />
hence, other body organs were also smaller than that obtained in the<br />
present work, including prepharynx and intestinal caeca. It was important to<br />
noticed that the genus Dicrogaster has been originally reported <strong>from</strong> fishes<br />
in the Mediterranean sea (Looss, 1902), this genus has apparently reached<br />
Fayoum area with Mugil spp. Which have been transferred to water bodies<br />
in Fayoum (Khalil, 1978).Al-Bassel (1987) recorded the parasite <strong>from</strong> Lake<br />
Wadi Al-Rayan in Fayoum Province and not <strong>from</strong> Lake Qarun, although<br />
specimens <strong>of</strong>. D. contractus collected <strong>from</strong> Mugil cephalus in the present<br />
work, collected <strong>from</strong> Lake Qarun.
