^1*6 ENTOZOA OF MONOTREMATA, ETC., I., 



MARSUPIALIA. 

 S.Macropus giganteus Zimm.(syn. M. major Shaw). 



Jfome:3ia/esi;im(Rucl.)(8,1 2,14,15,24,33,40,43,44,45). 



EchinoGOCcus polymorphus Dies. (22,31). 



Distomum (Fasciola) hepaticum Abildg.(4,12, 14,22, 24,33). 



Filaria wehsteri Cobbolc!(12,14,17). 



Filaria sp., Bancroft(l). 



Moniezia f estiva infests the gall-bladder and bile-duct. It was 

 originally described very briefly by Rudolphi(33) as Tcenia f estiva y 

 and figured by Bremser.(8) The locality mentioned was " Aus- 

 tralia." Dujardin(25) and Diesing(14) merely repeated Rudolphi's 

 short account. No other helminthologist, except Cobbold(12)j 

 appears to have studied this worm, though Blanchard(5) recognised 

 that, from Eudolphi's description, the species would probably 

 come under his new genus Moniezia. Krefft(24), Sti]es(25), 

 Zschokke(45,46,47) and Janicki(20) referred to this parasite, but 

 did not add any new facts. I have recently examined super- 

 ficially some specimens collected in New South Wales from this 

 host, which apparently belong to M. festiva. 



Pagenstecher(31) recorded the occurrence of hydatids {Echino- 

 cocciis poly7nor2)hus Dies.) in a Great Kangaroo which had died 

 in Cologne. 



• The common liver-fluke I>isto7num (Fasciola) hepaticum Abildg., 

 is not infrequently met with in the bile-ducts of various kangaroos, 

 including this species. Rudolphi(33), Diesing(14), Bremser(quoted 

 by Diesing), Cobbold(12), Bennett(4), Braun(7)(from Australia), 

 Kreift{24)(from New South Wales or Queensland), and myself (22) 

 (from New South Wales) have recorded its presence. 



Filaria wehsteri Cobbold(syn. F.macropodis gigantei Webster), 

 has been mentioned by Webster, Cobbold(12), and Fletcher(17) as 

 infesting the knee-joint of this host. Filaria sp., recorded by 

 Bancroft(l) is probably the same species. 



It is quite possible that the hydatid and the liver-fluke have^ 

 established themselves as parasites of the Marsupialia, since the 

 settlement of the white man, with his domesticated animals in.
