(1) Ilalteridium of Cafludurus Jathami. — A further speci- 

 men obtained by Dr. Bancroft at Eidsvold, Queensland, in 

 December, 1911, has been found infected. 



(2) Ilalteridium of Xinox hoohooh. — In our first joint 

 paper we recorded the presence of HaUertdunn in Xinox 

 hoohook (?) from Queensland. Another blood-slide from this 

 species, forwarded by Dr. Bancroft in September, 1911, from 

 Eidsvold, also showed their presence. 



(3) TlaJtendium of Xinox strenua. — Hfdteridia, very few 

 in number, were seen in slides made from this bird, and kindly 

 given to us in February, 1913, by Dr. Bancroft from 

 Eidsvold. 



(4) Ilalteridium of Gerygoue alhir/ularis. — Blood-slides 

 were obtained from a specimen of this species shot at Molong 

 in 1913. Halteridia of large size were present, occupying the 

 side and both ends of the host-cell, in some instances distinctly 

 but slightly displacing the nucleus. In some instances five- 

 sixths of the available space in the red cell was occupied by 

 the Halteriduim. Occasionally the side of the host-cell opposite 

 the parasite was reduced to a mere rim of protoplasm. The 

 pigment was coarse. 



(5) Halteriduim of Dicaeum hiriindiuaceuin (Swallow 

 Dicaeum). — Halteridia were detected in a specimen of Dicaeum 

 obtained on the Hawkesbury River, near Sydney, in March, 

 1912. The parasite occupied the side and both ends of the 

 containine: red cell. Pigment was moderately abundant, the 

 individual grains being of medium size. Pale forms were not 

 noticed. 



(6) Halteridiiim of Fardalotus melanocefhaUts (Black- 

 headed Pardalote). — Dr. Johnston and I have previously 

 recorded the presence of Halteridia in this species. Dr. Ban- 

 ■croft forwarded from Eidsvold in October, 1911, a further 

 film from this bird showing a few Halteridia. 



(1) Hedteridium of Melitlireptiis valid irof^tris (Thick- 

 iDilled Honey-eater). — A blood-film was obtained from this 

 species on Flinders Island, in Bass Straits, at the end of 

 November, 1912. Halteridia were present, but scarce. Both 

 pale- and dark-staining forms were noticed. A remarkable 

 feature was the scarcity of pigment, even in adult forms ex- 

 tending from end to end of their host-cells. In these just a 

 few minute grains or none at all were detected. Possibly this 

 is a specific feature. 



(8) Halteridium oi Myzomela sanguineolenta (Sanguineous 

 Honey-eater). — We have previously recorded Halteridia from 

 this species. Another infected specimen was forwarded by 

 Dr. Bancroft from Eidsvold in October, 1911, infested also 

 with Microfilariae, trypanosomes, and Leucocytozoa. The 

 Halteridia were numerous, with one or a few large grains of
