Xo internal parasites have as yet been recorded from the domestic pigeon 

 (Coluniba livia domestica) in this State, though an examination of material collected 

 recently in Brisbane revealed the presence of three distinct species. 



FACULIFER ROSTRATUS (Buchholz). 



In the tissues surrounding the pericardium and the groat blood-vessels, in the 

 subcutaneous region of the neck and also below the skin adjacent to the pectoral 

 muscles, there were found many small whitish parasites representing the hy]>opial 

 nymph stage of F. rostraius. a tiny Sarooptid mite belonging to the subfamily Anal- 

 ginai, which occurs in its adult condition as an epizoon infesting the barbules of the 

 feathers. 



The Hypopus apjiears to be fairly common heie, but the only Austr'aiian 

 record of its occurrence is that made by Dr. G. Sweet^ who found it in Melbourne 

 pigeons and published a figure and brief descriiition. 



Neumann^ has also given an account of this acarid. 



The same species is to be met with as an internal parasite of the pigeon in the 

 vicinity of Sydney, N. S. Wales. 



BERTIELLA DELAFONDI (Railliet). 



A number of ripe segments of this lare unarmeil cestode were brought to me 

 by one of my students, but unfortunately the greater part of the pigeon's intestine 

 had been thnjwTi away before I h:id li.id an (ip[)ortunity to obtain the remainder of 

 the worm.
