234 AUSTRALIAN REPTILIAN ENTOZOA 



Sanibon's and Dobell's specimens were obtained in 

 England, hence the original locality of the host is not 

 recorded. As has been already pointed out (Johnston, 



1909 b, p. 403), the snake must have come from the coastal 

 district of New South Wales, if the popular and scientific 

 names be correct. 



b i., Bothridium pythonis, Blainville — ^more commonly 

 known under the name of Soleiiophorus megaloce- 

 phalus {megacephalus) , Creplin. 



Baird (18()5 a p. 68 ; 1865 b p. 52) described a cestode 

 under the name of Bothridium arciiatum, from this host. 

 Monticelli and Crety (1891, reprint p. 17) after having 

 examined Baird's original material stated it to be a synonyat 

 of Blainville's species. Krefft (1871, p. 214) referred to 

 Baird's description. Specimens have been taken (Johnston 



1910 d, p. 28) from diamond snakes killed near Sydney. 



ii., Sparganum sp. 



I have several Bothriocephalid larvae from the sub- 

 cutaneous tissues of this host (Hawkesbury River). They 

 resemble at least externally, those recorded here from th^ 

 connective tissues of other reptiles such as Python varie- 

 gatus (N.S.W. and Queensland), Varanus varius (Burnett 

 River), Varanus gouldii (Burnett River), Dendrophis 

 punctulatus (Burnett River), while an allied form is occas- 

 ionally found in certain frogs between the muscles of the thigh 

 — Hyla cceridea (Burnett River and Sydney), Hyla aurea 

 (Sydney and Perth, West Australia). The parasites referred 

 to as Bothriocephalus mansoni, by Spencer (1892, p. 433) 

 and by Hill (1905, p. 378) whose specimens were found in 

 human beings, should perhaps be grouped merely a» 

 Sparganum sp., as their identity with Cobbold's forms i» 

 doubtful. Similar specimens of a Spargaiium have been 

 forwarded to me by Mr. Desmond, Government Veterinarian, 

 Adelaide, who found them in the subcutaneous tissues of 

 of a fox in South Australia. Probably the adult forms 

 of these occur in snakes. 



d. Ascaris sp., Krefft (1871, p. 214). 



A large Ascarid occurs fairly frequently in this species 

 and in P. variegatus (N.S.W. and Queensland)
