Inkerman Station, North Queensland. 477 



The three specimens from Inkerman are much more lightly 

 coloured than those in the British ]\luseum, especially on the 

 under parts, the brownish grey of the breast and lower neck 

 being broken up by creamy-white streaks, which merge into 

 tlie yellow markings on the throat. The lower neck of the 

 typical bird is of a more or less uniform sooty brown, only 

 becoming striated towards the breast ; the abdomen and vent 

 being pale buff, faintly streaked with sooty brown. In the 

 Inkerman birds these parts are much paler, being almost 

 white, while the back is likewise lighter and greyei\ Only one 

 of the Museum series bears any date, so that it is impossible to 

 say whether the difference is due to abrasion of the plumage 

 or not ; in the Inkerman examples the feathers are certainly 

 somewhat worn.

This species seems to vary considerably in size, but, 

 judging by the three skins sent home by Mr. Stalker and the 

 few examples bearing data in the British Museum, the 

 difference is merely sexual. The average measurements of 

 three males is as follows : wing 3"65 in., tail 3'2 in., cul- 

 men 0*75 in. ; that of four females : wing 3*35 in., tail 3 1 in., 

 culmen 0*65 in.

 Bill black ; feet blue-grey ; iris grey. 



The single skin collected by Mr. Stalker on Mount 

 Inkerman (an isolated hill overlooking a stretch of flat 

 country) differs noticeably from any of the nine specimens 

 in the National Collection. In its general coloration it is 

 olivaceous grey and entirely lacks the brownish hue of the 

 Museum examples and of those described by Gould [vide
