For many years I have endeavoured to obtain from 
various districts in New South Wales and Queensland 
endoparasitic material from the warrigal or dingo, my 
main object being to ascertain whether the adult hydatid 
tapeworm occurs in this host. The question as to whether 
the dingo is.indigenous to Australia or has been introduced 
by man, or has gained entrance by means of former land 
connections prior to the advent of man in our continent, 
is of considerable interest, but need not be dwelt upon here. 
Mr. R. Etheridge, Curator of the Australian Museum, 
Sydney, has recently published a review of the matter 
(1916). It is worthy of note that the animal does not occur, 
and apparently has not occurred, in Tasmania, and that 
remains of a species of Canis have been found in post- 
pliocene deposits at least in New South Wales. One 
cannot help believing that our wild dog is not a member 
of our indigenous fauna, but is an invader from the adjacent 
lands lying to the north. 
One difficulty has been to obtain material from pure 
dingoes since many of the animals are hybrids between 
C. dingo and the domestic dog. Some little time ago 
Dr. T. L. Bancroft forwarded me some parasites from a 
dingo shot near Eidsvold, Burnett River. | 
There are already two species of entozoa recorded from 
this host, viz., the hydatid and a pentastome, Linguatula 
dingophila, Johnson.
