this case the trachea passed twice down the left pectoral muscle to 

 near the vent before it entered the body. A few parasites {Mallo- 

 phaga) were found on one specimen only. 



Nycticorax caledonicus (Night-Heron). 



A common bird. The natives say that most of the Herons of all 

 species nest in the mangroves along the Robinson River. 



Nettopus pulchellus (Green Goose-Teal). 



Found on nearly all the swamps. In February pairs were numerous 

 in submerged open forest country near Borroloola, where they 

 evidently intended to nest. A native brought me three eggs on 3rd 

 March, which were taken from a nest built in the grass near a swamp. 

 Towards the end of March I saw several broods of young birds in a 

 waterhoJe near the head of the Wickham River.
