adults in the mesenteric veins. The finding of filarial embryos 

 in the blood of reptiles is rare, this being the only recorded 

 instance as far as Australian reptilia are concerned. 



24. Chlamydosaurus Kingii, Gray. The frilled lizard. 



d Strongylus paronai, Stossich. 



Some specimens taken by me from a frilled lizard for- 

 warded by Dr. Bancroft (Burnett River), are provisionally 

 referred to this species. 



25. Varanus indicus, Daud. 



h Palaia varani, Shipley, 1900, p. 548. 



d Physaloptera varani, Parona. Stossich in Shipley, 

 1900, p. 560. 



Both species were collected by Dr. Willey in New 

 Britain. In regard to Palaia varani, the account given 

 does not allow of the genus being properly placed. It 

 seems to me probable that Palaia is a synonym of Proteo- 

 cepkedus. 



26. Varanus varius, Shaw. The monitor.

 '/,p. 683 (N.S.W.) ; 1911 a, p. 487. (Burnett River) 



Hcemogregarina sp. Gilruth, 1910, p. 36 (Victoria) 

 is the same. 



h i Proteocephalus tidswelli, Johnston, 1910 a, p. 103 ; 

 1910 b, p. 87 (X.S.W.) 



This species was first described as Ichthyotaenia {Acan- 

 thotcenia) tidswelli, but Benedict (1), La Rue (2) and others 

 have shovni that Weinland's genus has priority over Lonn- 

 berg's Ichthyotaenia. I have already shown (1910 a, p. 113- 

 114) that Linstow's genus Acanthotaenia is a synonym of 

 Proteocephalus.
