The bill appears to vary very much in colour; being in some instances entirely ash-grey, except at the tip, where it is black; while in others the basal two-thirds is black and the tip grey: whether this difference is occasioned by age or sex has not yet been ascertained. The figure represents a male of the natural size. [Illustration: GRALLINA AUSTRALIS. _J. Gould and H. C. Richter del et lith._ _C. Hullmandel Imp._ ] GRALLINA AUSTRALIS, _G. R. Gray_.

Future research will, in all probability, establish the fact of this bird being universally dispersed over the greater portion of Australia; I have specimens in my collection from New South Wales, Swan River, and Port Essington, all of which are so closely alike that no character of sufficient importance to establish a second species can be detected. Those that came under my observation in New South Wales were never seen very near the coast, but frequented the rich alluvial flats and sides of the creeks and rivulets of the interior.
