38 ENDOPARASITES RECORDED IN QUEENSLAND. 
proved that several species of a freshwater mollusc, 
Planorbis sp., can act as intermediate hosts. Species of 
this genus are common in our water supply and in ponds, 
and no doubt could serve as a host just as some other 
species of freshwater gastropods have become the inter- 
mediate hosts of the liver fluke, Fasciola hepatica, in 
Australia. 
One need only mention that Ankylostomes are 
particularly abundant in Egypt. They are widely spread 
amongst the inhabitants of our own coastal districts. 
Given certain conditions, there is danger that some 
of these parasites may become endemic.
