It appeared to me that it would be of some scientific us 

 well as of economic value to bring together all the refer- 

 ences known to me, concerning the occurrence of endo- 

 parasites in domesticated and introduced birds in Australia. 

 In addition to those mentioned in the following list, there 

 are others which I have not yet identified. The fact that 

 many of these introduced birds harbour the same tape- 

 worms as in other parts of the world, seems to show that 

 the larval stages have probably accommodated themselves 

 to local intermediate hosts.

 This spirochaete is the cause of fowl tick-fever or spiro- 

 chaetosis (spirillosis). Its real name is perhaps S. anscrina, 

 Sacharoff, since Galli-Valerio 1 regards both S. gallinarum, 

 R. Bl. and S. marchouxi, Xuttall to be identical with the 

 earlier described S. anscrina, which produces a similar 

 sprochaetosis in geese and ducks. Doflein, 2 Nuttall," Liihe 4 

 and Calkins' regard them as different organisms, the last 

 mentioned author placing them both under Treponema, 

 and calling the fowl tick-fever organism Treponema <jal- 

 lin trum, March, and Salimbeni, 1903. Cleland recorded 



iharoff is treated as a different organism (p. 89).
