Capt. Lawtou recently published an account of th©- 

 early clinical features of the serious disease caused by S. 

 mansoni (1917, p. 21). He found latoral-spined ova in 

 stools of a number of Australian soldiers in a Cairo Military 

 Hospital. In addition to the ova, the faeces were found, 

 in some cases, to contain other parasites such as Entamoeba 

 eoli, Trichomonas intestinalis, Lamblia and Blastocystis 

 hominis. All these men were subsequently discharged to 

 Australia. 



Nematoda. 

 Dictyocaulus arnfieldi Cobbold. 



In 1893 in his report on Stock Diseases in Queensland,. 

 Dr. T. L. Bancroft recorded the occurnuice of lung worms, 

 Strongyhis micrurus Mehlis, in sheep and horses. Perrie 

 referred to their occurrence in horses in Sydney, using the 

 same nr.me. 



The parasite is almost certainly D. arnfieldi from the 

 horse (Sydney and Brisbane) and 1). filaria from sheep 

 (Queensland). S. micrurus { = D. viviparus) is the lung worm 

 of calves. 



Synthetocaulus cajrillaris MuUer. 



Dr. J. B. Cleland forwarded portion of a goat's lung 

 parasitised by nematodes which have been provisionally 

 identified as S. capillaris (Sydney District). Only an 

 extremely brief account of the nematode is available to 

 me. Lungworms had not been previously reported as 

 occurring in goats in Australia. 



Heligmosomum braziliense Travassos. 

 About a dozen specimens of this tiny strongyle were 

 collected by Miss B. B. Taylor (Brisbane, May, 1918) from 

 the intestine of a rat, kindly determined by Mr. H. A. Long- 

 man; Director of the Queensland Museum, as Epimys 

 rattus. This is the only occasion on which H. braziliense 

 has been reported from E. rattus. I have recorded its 

 presence in E. noj'vegicus in Brisbane and Sydney (1918, 



p. 56). 



Capillaria retusa Raill. 



From the walls of the alimentary canal of the domestic 

 fowl in Brisbane — not previously recorded from Queensland- 

 though known to occur in Sydney and Melbourne.
