Toenia crassicollis, Rud. 



Found in ^a local oat (Brisbane). Not previously 

 recorded from Queensland. 



Cysticercus fasciolaris, Rud. 



This bladderworm stage of Tcenia crassicollis is fairly 

 commonly met with in the liver of local rats {Mus decumanus 

 and M. alexandrinus) and mice {M. museulus), but its 

 presence in Queensland does not appear to have been 

 reported. 



Dipylidium caninum (L.) 



A common parasite in local dogs and cats (Brisbane), 

 but apparently unrecorded from this State. 



Diploposthe Icevis. Bloch. 



This large and interesting cestode has again been 

 met with in a White-eyed Duck, Aythya australis, kindly 

 forwarded b}^ Dr. Bancroft from Eidsvold. It is now 

 detinitely recorded from Queensland. Krefft, who 

 described the parasite as Toenia tuherculata, did not refer 

 to a definite locality, mentioning merely that his material 

 was collected in either Xew South Wales or Queensland. 



M etroliasthes lucida, Ransom. 



Found in the domestic turkey, my specimens being 

 collected in Sydney from material supplied by Mr. Thos. 

 Steel, through the Bureau of Microbiology, Sydney. This 

 identification constitutes the first record of the occurrence 

 of the species in Australia. 



Davainea cesticilhis, Molin. 



Has been identified from a local fowl (Brisbane). Not 

 previously recorded from Queensland, 



Davainea tetragoria, Molin. 

 Has been found several times in local fowls (Brisbane). 

 This species has been previously recorded by Dr. Sweet 

 (1910, p. 243), as occurring in Rockhampton. 



Davainea varians. Sweet. 



This tiny parasite of domestic fowls has been described 

 by Dr. G. Sweet (1910, p. 243), but it seems to me to be 

 synonymous with D. proglottina, which is admittedly a 

 variable species. The main difference appears to be in the size
