Distribution.— Southern Queensland, Central Australia. 



/■ |3\HE present species is undoubtedly the rarest passerine bird in .Vustralia. Since Gould 

 JL described the type, an adult male, in 1848, up to the present no other specimen has 

 been recorded, although an apparently closely allied representative — Cinclosoma marginatum — 

 has been described by Dr. Sharpe, also from a single specimen, obtained in North-western 

 Australia. The type of Cinclosoma castanothorax was procured by the late 'Sh. Charles Coxen 

 "in the scrubby belts of trees growing on the table-land to the northward of the Darling Downs, 

 Queensland." In the original description, Gould states the stripe over the eye is white; this is
