NOTES on AUSTRALIAN ENTOZOA, No. I. 



(Communication from the Government Bureau of Microbiology, 



Sydney.) 



By T. Harvey Johnston', M.A., B.Sc, Parasitologist, Bureau of 

 Microbiology ; Hon. Zoologist, Austi^alian Museum. 



Australian Entozoa have until now been comparatively 

 neglected. The parasites of man and of the common domesticated 

 animals are not accurately known. There were only occasional 

 references scattered in medical and agricultural journals until 

 Miss G. Swee^D.Sc., 1 of Melbourne, published her excellent census 

 a few weeks ago in the Royal Society of Victoria (March, 1909), 

 whilst this note was in the press. In order that this series of 

 records should contain as much information as possible I pre- 

 ferred to amend it by incorporating Miss Sweet's new species and 

 a few references mentioned by her, which I had no opportunity 

 for finding. All records mentioned in Dr. Sweet's paper have 

 accordingly been denoted thus f in front of the reference. 



In all probability, many of the records of the occurrence of 

 Eutozoa in Australia are unreliable, as we know to-day that it 

 requh'es a specialist to identify with certainty even common 

 species. All specimens that I have examined will be marked 

 with an asterisk following the locality from which the specimens 

 were obtained. 



Many parasites occur here as accidental infections, by which I 

 mean that they have been collected in Australia from hosts that 

 have been infected in some other country, e.g., Schistosomum 

 hcematobium, Bilharz, introduced from South Africa. Such 

 Entozoa may or may not become established here. All such 

 records, when the history is known, will be denoted (introd.)
