WORM-NESTS IN AUSTRALIAN CATTLE. ] 59 



as a new species, Filavhi yibsoui, 1 the one by Mr. Henry 

 Tryon already mentioned dealing with some of the literature 

 and official papers, and another by Sydney Dodd'in the 

 same number of the Queensland Agricultural Journal. 



When examining a number of dromedaries imported from 

 Karrachi in India into Western Australia in 1907, one of us 3 

 found in several animals, very similar fibrous worm-nests, 

 though in general smaller in size. These were situated in 

 the subcutaneous tissues of the neck (where one was mis- 

 taken during life for an enlarged lymph gland) and under 

 the tail. The identity of this parasite has not so far been 

 possible owing to failure to extract certain parts from the 

 fibrous mass, so it cannot be said whether it is identical or 

 not with that of cattle though we believe it to be so. 



Geographical Distribution. In Queensland cattle, 



slaughtered at the Sydney abattoirs, the nodules are com- 

 mon. Park's specimens were from cattle in the Burnett 

 district of Queensland. Gibson quotes Stanley to the effect 

 that at least 50;'' of the animals slaughtered in Sydney in 

 or about 1892 were affected. This would include Queens- 

 land cattle, but also many bred in New South AVales. We 

 are informed by Messrs. C. J. Vyner and W. G. Johnston 

 of the Veterinary Division of the Health Department of 

 this State that nodules can be found in cattle bred in the 

 neighbourhood of Sydney. We have seen them from the 

 northern rivers and western districts of New South Wales 

 and from the Northern Territory of South Australia. 

 Barnard and Park state that the disease is unknown in
