five species of Macropus, viz., M. yiganteus, M. robust us, M. 

 thetidis, M. dorsalis and M. ualahafus. 



3. Macropus parryi Bennett. 

 Corcidium. (Eimeria) sp., was found (Johnston, 1910, a, 

 p 433) in the intestinal mucosa of several of these wallabies, 

 sent from South-eastern Queensland to the Sydney Zoological 

 Gardens. The organism appears to be pathogenic to various 

 macropods, and has now been recorded from .1/. giyanteus, 

 M. parryi, and M. thetidis. 



4. Macropus thetidis Less. 



1. ErJiiiiorocrus (jrdiiuloiius Gmel. Hydatids were found, 

 jjost morff'/N (Johnston 1909, b, p. 79; 1910, a, p. 523) in 

 the lungs of some wallabies of this species which were collected 

 by Mr. H. Burrell, in the New England district, N.S.W., 

 and sent to the Sydney Zoological Gardens. 



2. Corcidium {Eiiiicrut) sp., Johnston, 1910, a, p. 523, 

 from the intestinal mucosa (New England, N.S.W.). 



5. Macropus ualabatus Less, and Garn. 



1. Eclmtococcus yraiiulosus Gmel. Hydatids were recog- 

 nised (Johnston, 1909, r, p. xxix.) in the lungs of a black 

 wallaby, the specimen being collected in the Gosford district, 

 N.S.W., by Mr. L. Gallard. 



2. Bancroftielhi tenuis, Johnston. This cestode was taken 

 from the intestine of this host in Victoria, by Mr. A. S. Le 

 Souef ; a description will be found below. 



6. Macropus ruficollis Desm. 

 Distotnum (Easriohi) hepaticuni Abildg. The presence of 

 the liver-fluke of sheep and cattle in the bile-ducts of the red- 

 necked wallaby, is now recorded for the first time. The only 

 other marsupial from which it is specifically recorded is J/. 

 giganteus, though Cobb (1904, p. 659) mentioned that he 

 had found the parasite in wallabies, but without designating 

 the species of the host. My specimens were collected, for me,
