DESCRIPTION OF NEW HAEMOPROTOZOA FROM BIRDS IN N.S.W. 75 



DESCRIPTIONS of NEW HAEMOPROTOZOA from 

 BIRDS in NEW SOUTH WALES, with a note on 

 the resemblance between the spermatozoa of 

 certain honeyeaters (pam. meliphagid.e) and 

 Spirochaete-trypanosomes.

For some years, one of us (J. B. Oleland) in Western 

 Australia, has examined, as opportunity offered, blood films 

 from various native birds with the object of detecting 

 parasitic protozoa, but with uniformly negative results. 

 Recently we have made a thorough examination of the 

 blood and tissues of various wild birds in the neighbour- 

 hood of Sydney, with the result that no less than six 

 apparently new species of protozoa have been discovered 

 by us, four of which form the subject of this paper. The 

 importance of studying and describing these forms has 

 appealed to us, as thereby light may be thrown on the life- 

 histories of some of the protozoal parasites so destructive 

 to various animals of economic importance. With this 

 view and with the object of helping other observers in 

 Australia to correlate their results, we have compiled this 

 paper descriptive of some of the types that we have so far 

 encountered. 



It is with considerable hesitation that we have ascribed 

 specific names to such of these species as manifest slight,
