ON A NEW H^MOPROTOZOAN — JOHNSTON. 259 



I liave recently taken a number of ticks from the specimen but 

 have not yet examined them to ascertain whether the other stage 

 in the life-cycle is present in them. 



I wish to express my thanks to the Director of the Bureau of 

 Microbiology (Dr. F. Tidswell), for his assistance and for his 

 courtesy in obtaining permission to publish this note of work, 

 performed, mainly, in the State Laboratory ; also, to Mr. A. R. 

 McCullocIi, of this Museum, for determining the snake. 



The figures were drawn using compensating ocular, one- 

 eighteenth oil immersion objective and a Zeiss camera lucida. 



A type slide has been presented to the Trustees of the 

 Australian Museum, Sydney.
