The present paper is a continuation of the systematic 

 examination for liaematozoa of blood slides from Australian: 

 birds, of which two previous numbers have already been 

 contributed by Dr. T. Harvey Johnston, in association with 

 the present writer. The present paper deals with the examina- 

 tion of further slides up to the end of 1914. The majority of 

 the birds were obtained in New South Wales, but some came 

 from South Australia, Queensdand, and the islands of Bass 

 Straits. 



I would here like to express my gratitude to Dr. T. L. 

 Bancroft, of Eidsvold, Queensland, who has so generously 

 forwarded many blood-films for examination, as well as to 

 my former colleague. Dr. T. Harvey Johnston, with whom 

 some of the earlier specimens in this paper were conjointly 

 examined. 



The haematozoa found in Australian birds are comprised 

 in the protozoan genera Halferidium, Plasmodnim , Tri/pano- 

 soina, and LevcocytozGoti (?), whilst Microflariae have also 

 been found. 



Our joint and separate researches have now shown the 

 presence of Halter (did in birds in all the States of the Com- 

 monwealth, except Victoria, from which latter State we have 

 as yet had no opportunity of examining specimens. The genus 

 Plai^m odium has been found in sparrows in Sydney, and has 

 been recorded from Victoria by Gilruth, Sweet, and Dodd, and 

 from Queensland by Breinl. We have met with trypanosomes 

 in Queensland birds, and in two instances in birds from New 

 South Wales, one of these cases being from Grafton and the 

 other from near Sydney. Trypanosomes seem rarer in birds 

 in New South Wales than in those from Queensland. Leucn- 

 cytozoon ( ? ), which we have thought may possibly be an intra- 

 corpuscular stage of a trypanosome, has been found chiefly in
