This paper is offered as the second and more specialised 
portion of my presidential address (1916b). It is an 
attempt to bring together, for the first time, a list of all 
the internal parasites recorded definitely from Queensland, 
whether protozoon or helminth*. All records which are 
not explicit are omitted, e.g., those made by Krefft in 1871, 
who mentioned that the forms recorded by him, except 
a few which were more or less localised, were collected 
in New South Wales or Queensland. 
With the exception of Wolffhtigel’sf catalogue of the 
parasites of Argentina and Hall’sf list of those occurring 
*T have also included members of those genera of Arthropoda which 
are generally grouped amongst the helminths, e.g., the Linguatulida and 
the larvae of the botflies, Oestrus, Gastrophilus, etc. There are, however, 
many other internal parasites belonging to the phylum, as for example, 
Copepods and Isopods infesting the gills and buccal cavity of our marine 
fishes, Sacculina in crabs (Port Curtis), Copepods in the mantle cavity of 
certain Gastropods, Ascidiicola sp. in the pharynx ot Cynthia preputialis, 
Unionicola sp. (a mite) in the gills of our freshwater mussels, ete.
