32 ENDOPARASITES RECORDED IN QUEENSLAND. 
in Colorado, I do not know of any attempt to list the 
recorded protozoon as well as helminth endoparasitic 
fauna of any country. Queensland occupies a large tract 
of country, larger than many of the European countries 
taken together, and possesses a vast fauna on land and 
in its waters, the greater part of which is as yet unsearched 
for entozoa. This is particularly the case with regard to 
our fish, reptiles and invertebrates. Even the domesticated 
animals have not yet been systematically examined. 
In spite of these facts, the entozoa of Queensland 
and New South Wales have received much more attention 
than those of the other Australian States. 
In 1909, Dr. G. Sweet published her census of the 
endoparasites of the native fauna and domesticated 
animals in Australia (1908), but the protozoa, of which 
very few were then known, were not included. The 
number of hosts in Queensland from which worms were 
definitely there recorded, is considerably less than 40 
—nearer 30, and of these about one-third were birds 
in which Dr. T. L. Bancroft (1890a) found filarie. 
Since that time, several workers have been engaged in 
the work and the number of Queensland hosts from which 
parasites are recorded, is now about 180. From many 
of them, however, only hemoprotozoa have been as yet 
reported. This list comprises about 30 mammals, nearly 
90 birds, nearly 30 reptiles, 6 frogs, 18 fish, and about 
a dozen arthropods. Our molluscs have not yet been 
searched. 
Dr. Sweet’s list contains the names of about 80 native 
and about 15 introduced hosts in Australia recorded as 
harbouring endoparasites. This is mentioned merely to 
emphasise the advance which has been made in the past 
seven years, the chief workers in Queensland parasitology 
being W. Nicoll, A. Breinl, 8. J. Johnston, J B. Cleland 
and T. H. Johnston, the two last-named being indebted 
especially to Dr. T. L. Bancroft for abundant material, 
much of which still awaits investigation. 
A list of the parasites recorded from man and the 
domesticated animals in Australia was published some 
years ago (Johnston, 19106). I have also given a census
