Gould, ill his 'Birds of Australia/ has figured the female 

 of Malurus lamberti as female of .1/. leucopterus (i. e. Malurus 

 cyanotus) and the female of M. leucopterus as the female of 

 M, lamberti. 



Leggeornis lamberti occidentalis is a very silent bird, and 

 I never heard any song from those seen on Dirk Hartog, 

 nor yet from any of the hundreds I have met vrith in 

 various localities of mid-west Australia, from Shark's Bay 

 to North-west Cape. It seemed as if this species \\ as partial 

 to feeding in the scrub close to the beach, but many family 

 parties were also seen further inland on the island. It was 

 a common occurrence to notice parties composed of female 

 and immature males of both Leggeornis I. occidentalis and 

 Nesomaturus I. leucopterus feeding together, and it took 

 some practice to be able to distinguish the species and sexes 

 with certainty. Very small, but exceedingly active young 

 birds were seen on 13 October, 1916, having evidently only 

 recently left the nest. Others were noted on subsequent 

 dates, but two adult males, shot on October 21, were certainly 

 not breeding then. 



Average measurements of an adult male in inches : — 

 Total length 5'12; wing 1-87; tail 2-75. 



Leggeornis lamberti occidentalis was fairly common on the 

 Peron peninsula, but no specimens were observed in the 

 short time spent on Edel Land. 



Specimens from Dirk Hartog appeared to be the same as 

 those from the Peron, but the series of skins obtained have 

 not yet been worked out. Comparison of skins from 

 both these localities with skins at the Perth Museum 

 from Bernier Island, prove the former to differ from the 

 last-named. 



Nesomalurus leucopterus leucopterus. 



After an interval of nearly one hundred years the original 

 Malurus leucopterus Dumont, subsequently figured by Quoy 

 & Gaimard, has again been obtained in the locality where the 

 type-specimen was got in 1818, namely Dirk Hartog Island 

 on the west side of Shark Bay in Western Australia. The
