 of the Australian Museum, Sydney, for confirmation of identity. Soon afterwards there was published one of the "Records" of that institution (vol. vii., No. 4, 1909), under the date 30th August, 1909. This record describes the plumage of the female of Cinclosoma marginatum (Sharpe), in addition to other interesting information, and purports to have been taken from a skin shot by Mr. C. G. Gibson, Assistant Geologist to this State. The skin referred to was received so long ago as July, 1908. If this specimen was in a recognizable condition, it is odd indeed that such an interesting bird should so long remain undescribed. Mr. Gibson was recalled from his work at Wiluna very shortly after obtaining this specimen, and was sent out as geologist, on behalf of this State, to accompany the Transcontinental Railway survey party. This party, however, returned to Perth prior to Christmas of the same year, so that, had further information been required by Mr. North, Mr. Gibson was at hand to supply it. Cinclosoma marginatum happens to be not only a very loose-plumaged bird, but, in addition, the skin about the loins, head, and neck is remarkably tender. I defy anyone but a practised hand to make a skin without losing a large percentage of the feathers and badly tearing the skin, and, even if fairly successful in that direction, to restore the various feather tracts to their proper positions in the completed skin. Mr. Gibson deserves every credit for his interesting field notes, but why these should be necessary in describing the plumage of the female it is hard to see. Mr. North has recently described two new species of birds collected by myself at Lake Way, and without applying to myself or to Mr. H. L. White for further particulars other than were attached to the skins. In addition to describing the plumage of the female, the record contains an excellent photograph of the nest and eggs taken in situ by Mr. Gibson. This is accompanied by a description of the eggs and nest by Mr. North. According to the report, Mr. Gibson took nests with eggs on 13th June, 30th August, and 1st September, 1908. There is some discrepancy here. On the two last dates Mr. Gibson was away on the Transcontinental Railway survey. There can, however, be no doubt of the identity of these eggs, but it is as well to be accurate in records of this nature. It is probable that the two latter clutches were collected by some local man on behalf of Mr. Gibson.

I do not consider Cinclosoma marginatum a shy bird. As before mentioned, it still frequents country where active mining operations are in progress, and can be seen within easy distance of the main street of Wiluna. All that is necessary is to walk through the bush quietly, keeping one's eyes well ahead. At the first alarm, perhaps, a pair may run under a bush, but if the observer stands motionless the female, followed by the male, soon comes out again, and both will quietly feed right up to one's feet if reasonable quiet is maintained.

As to its geographical distribution, Mr. Gibson is approximately correct. Probably its southern limit overlaps the northern limit of C. castanonotum about the latitude of Menzies or Leonora. How far east it extends is unknown. Westwards I have met with it within 100 miles of the coast, in the latitude of Geraldton; but, despite much search for it on the Pilbarra goldfield, I failed to find it there. No doubt it extends much further north than Wiluna. I have little doubt that the specimens of C. castanonotum recorded as shot near Separation Well (see Campbell's "Nests and Eggs," p. 256), should have been referred to the present species and not to the latter.
