"212 NOTES ON MISCELLANEOUS ENDOPARASITES. 



• copperheaded snake, Denlsonia superba (Victoria) and an 

 unnamed snake collected by Dr. J. B. Cleland* on Flinders 

 Island (1918a). Quite recently he referred briefly to the 

 parasite and published ii, figure illustrating its anatomy 

 (1918b, p. 374). 



I obtained D. macalpini from the oesophagus of 

 Denisonia superba and the black snake Pseudechis po.phy- 

 riacus in Sydney district, recording its presence under the 

 name Hemiurus ( Apoblema) sp. (1910a, 1911). This 

 parasite of venomous snakes seems to be fairly widely 

 distributed in Eastern Australia. 



EcJiinochasmus tenuicollis S. J. Jnstn. 

 Recently described by S, J. Johnston, (1916, p. 206) 

 from a cormorant, Phalacrocorax melanoleucus , Tuggerah, 

 N.S.W. I have identified as belonging to this species a few 

 trematodes collected from the same host species near Long- 

 reach, Thompson River, by Miss M. J. Bancroft (August, 

 1918). In ray specimens the vitellaria extend further 

 forwards, reaching the posterior edge of the ventral sucker, 

 while the male and female glands are relatively more remote 

 from the hinder end of the animal, being situated nearer the 

 ventral sucker than shown in the original figure. 



Schistosomum spp. 

 Some time ago reference was made to the likelihood of 

 human blood flukes being introduced into Australia by 

 returning troops from Egypt and neighbouring countries 

 (Johnston, 1916, p. 37). In 1917 urine from returned 

 /soldiers in Queensland, submitted to uie for examination, 

 was found to contain Bilharzia ova. Most specimens 

 possessed terminal spines {S. haematobium Bilh.) but occas- 

 ional lateral-spined eggs {S. mansoni Sambon) were present 

 in addition. Thus both species of human blood fluke are 

 at present in this State. It is not unlikely that under 

 certain conditions these may become endemic. One 

 species, presumably S. haematobium, on account of its 

 South African origin, has become established in one locality 

 in West Australia. Major Cherry gave an interesting 

 summary in his article on Bilharziosis (1917). 



*Dr. Cleland has informed me that the snake was Notechis scutalus.
