affected with the trichina. In 1898 Dr. Halford (Austr. Med. Gaz., 

 1898, p. 263) read a note on and exhibited before the Queensland 

 Branch of the British Medical Association specimens of this 

 parasite, distributed throughout the muscular substance of a 

 patient that had been operated on for epithelioma on the floor of 

 the mouth. In 1902 Professor Watson, Dr. Angas Johnson, and 

 Mr. Veterinary-Surgeon Desmond (A.M.G., 1902, pp. 106, 120 and 

 415, and Trans. Inter. Med. Congr. Austr., 1905, pp. 370, 380, 

 S. Australia) reported a case whose nature was discovered during 

 an operation for malignant growth in the neck. The disease was 

 traced to infected meat received from outside Australia. Braun 

 (" Animal Parasites," Engl., transl. 1906, p. 319) mentions its 

 occurrence in man in Australia. 



4. Trichocephaliis trichiuvus L., better known as T. dispar 

 Rud., a parasite infesting the human ca:;cum, has been recorded on a 

 few occasions from Queensland and New South Wales, but not as 

 yet from any of the other States. There is little doubt that it 

 occurs in them also. Hogg (Austr. Med. Gaz., VIII., 1888-9, p. 133) 

 reported it from Queensland at the same time as he made known for 

 the first time the existence of the hookworm in Australia. Bacot 

 (A.M.G., XL, 1892, p. 430) also found both of these worms present 

 at a post-mortem at Cairns, North Queensland. Bancroft in 1893 

 (A.M.G., 1893, p. 258) mentioned that this helminth was common 

 in Brisbane. Lawes (A.M.G., XIV., 1895, p. 446) found it in com- 

 pany with Ankylostoma in 1895 while performing a post-mortem 

 in Brisbane Hospital on a boy who had come from the Tweed 

 Heads, New South Wales. Other references were made by Molhson 

 in 1898 (Trans. Intercol. Med. Congr., 1898, p. 417. Queensland 

 and N.S. Wales), and by Johnston in 1909 and 1910 (I.e. 1909, 1910, 

 Queensland and N.S. Wales). 



5. Strongyloides intestinalis Bavay, also known as Anguillula 

 or Rhahdonema stercoralis, was found in Queensland in 1896 by 

 Ashworth (Austr. Med. Gaz., XV., 1896, p. 483), in company with 

 Ankylostoma. He did not identify it definitely, but there is no doubt 

 but that this is the species referred to. Turner (A.M.G., 1896, p. 484) 

 refers to Ashworth's find, and remarked that the worms were 

 neither Oxyuris nor Ankylostoma. 



Belonging to the Strongylidae in its wide sense are the two 

 hookworms Agchylostoma duodenale and Necator americanus, both 

 reported from Queensland. Besides these Eiistrongylus gigas is said 

 to have been found. The last mentioned was recorded by Allan 

 (A.M.G., XVI., 1897, p. 607) as being passed with the urine by an 

 old man. This is evidently a case of mistaken identity, as a glance 

 at his account will show. It was almost certainly not a worm at all. 



6. Agchylostoma duodenale Dubini. Undoubtedly the three 

 most important human parasites in Australia are the hydatid, the
