ox ECHlNOCOCiU^S IX A WATJ.AP,Y. 



By THOS. L. BANCROFT, M.B. 



Ox nth April, 1800, on the shores of Deception Bay, I 

 shot a forest wallaby f HabiKitunis dorso/isj whose luni;-s were 

 infested with what appeared to be hydatid cysts of Taenia 

 echinococcus. Microscopic examination of the scolices or echino- 

 coccus heads confirmed that opinion. The cysts are of the 

 exogenous variety and are 1 inch to H inch in diameter. Any 

 fact in the life history of echinococcus is of extreme importance 

 and worthy of record, inasmuch as it may help in the extermi- 

 nation of this dreaded parasite. It would be a wise thing to burn 

 carcasses of dead marsupials as well as of sheep and oxen to 

 prevent as far as possible dogs and dmgoes eating them. The 

 livers and lungs are the especially dangerous parts, and dogs on 

 no account should ever be fed with them.
