In former papers we have already made known some of the 

 results obtained by us while studying the haematozoa of 

 certain groups of our Australian fauna, namely the Am- 

 phibia, 1 Reptilia, 2 and Birds. 1 In this note we have dealt 

 with some trypanosomes found in certain fresh-water fish, 

 and have given a list of our negative and positive findings 

 as regards haematozoa. We have also made mention of a 

 parasitic disease affecting one of our food fishes, though the 

 parasite, a myxosporidian, is not a haematozoon. 

 Trypanosoma anglillicola n. sp. from the Long-finned 

 Eel, Anyuilla relnhardtii, Steind, and the Marbled 

 Eel, A. mauritana, Bennett. (Figs. 1 - 6.) 

 To Dr. T. L. Bancroft we are indebted for the first 

 specimens of this trypanosome which occurs in the blood of 

 the above fresh- water eels. Of the infected hosts belong- 

 ing to the former species, one was captured in January, 

 1910, and two in May, 1910, very few of the parasites being
