588 Mr. T. Carter on the Birds of [Ibis, 



similar, but the Peron birds appeared to be much more 

 wary and difficult to obtain. Sometimes tliey run along the 

 ground, with tail in a horizontal position, at great speed, on 

 the bare spaces o£ sand between the bushes, and dodge about 

 so that it is often difficult to keep thera in sight, even 

 when one runs after tliem. At other times they hop with 

 tails erect, and on several occasions, having only caught 

 a momentary glimpse of a bird, I mistook it for an 

 Amytornis. 



The specimens were obtained between 20 November, 1916, 

 and 18 January, 1917, and showed no signs of breeding. 



No Calamanthus has ever been observed in the vicinity of 

 Carnarvon at the mouth of the Gascoyne River, where I 

 have systematically observed and collected birds since 1886. 

 Nor has any Calamanthus been seen south of Mauds Landing 

 (160 miles north of Carnarvon), where C. c. rubiginosus 

 appears to find its southern coastal limit. 



Ephthianura albifrons westralensis. 



White-fronted Chats were only observed at one locality 

 on Dirk liartog Island, viz., the open flat around the west 

 well, three miles from the homestead. A few small parties 

 of these birds were always in the vicinity of this well. They 

 were not seen on the Peron. 



Parephthiannra tricolor assimilis. 



These Tricoloured Chats were only seen once on Dirk 

 Hartog Island, viz. on 1 May, 1916, at the Cape Inscription 

 Lighthouse, at the extreme north end of the island. One 

 bird was shot for identification from a small party of them. 

 A heavy north-east gale was blowing (i. e. off the mainland). 

 This species is very common about the Gascoyne and further 

 north, after either winter or summer rains. It was not seen 

 on the Peron. 



Acanthiza sp. ? 



No Acanthiza was observed on Dirk Hartog Island, which 

 is remarkable, as the prevailing scrub there suggests a good 

 habitat.
