12. Denisonia superba, Gunther. (Syn. H oplocephalus 



superbus). The Copper-headed Snake. 



b i Piestocystis hoplocepkali , Hill, 1894, p. 49. 



Occuring in cysts in the peritoneum around the intestine. 



(N.S.W.) 



ii, Proteocephalus sp., Johnston, 1910 a, p. xviii. 



This cestode is speeificaUy identical with that referred 

 to above as occurring in Pseudechis australis, and differs 

 only in minor details from Proteocephalus gallardi. Recorded 

 from Sydney district under the synonym IcMkyotaenia sp. 



c i. Hemiurus sp. 



From the oesophagus (Sydney). Recorded as Apoblema 

 sp. (Johnston, 1910 a, p. xviii). It also infests the Black 

 Snake. 



d Trichosomum sp., (Johnston, 1910 a, p. xviii). From 

 the intestine. (Sydney.) 



/ Porocephahis terethiscuhis, (Baird)- 



This pentastome was described by Baird (1862, p. 114) 

 halving been taken from the lung of a snake belonging to 

 this species which had died at the London Zoological Gar- 

 dens. Krefft (1871, p. 211) hereby mentioned Baird's 

 species. B. Spencer (1892, p. 1) found the parasite in D. 

 superba (Victoria) as well as in Pseudechis porphyriaciis. 

 Shipley (1898' p. 76) referred to its occurrence in this host. 

 Porocephalus sp., recorded by me (1910 a, p. xviii) from the 

 same host (Sydney district) belongs to Baird's species. 



13. ^OTECHis scuTATUS, Peters — syn. Hoplocephalus curtus. 

 D. &. B. The Tiger Snake. 



h Proteocephalus gallardi, Johnston. 



Tapeworms which I have taken from a Tiger Snake 

 killed near Sydney, have been identified as belonging to the 

 same species as those from the black snake. Notechis 

 scutatus is thus a newly recorded host for this entozoon. 

 Kitson's reference (1904, p. 147) to the occurrence of a long 

 cestode in this host is of no value.
