in ewingi , darker throat, the dusky bases of the feather showing more con- 
spicuously than in the common species, the fulvous edgings of the primaries, 
and the darker abdomen. The measurements of two specimens, one of ewingi 
and one of diemenensis , from the same district (New Norfolk) are : Acanthiza 
ewingi : wing T95, tail T7, tarsus 0’95. Acanthiza diemenensis : wing 
T93, tail T59, tarsus 0*75. 
The species has recently been procured by Mr. A. G. Campbell on King 
Island. An examination of the specimen from that island and one from Mt. 
Wellington reveals the same characteristics as noted here, and the extra length 
in tail and tarsus of the same. The King Island specimen is slightly paler on 
the forehead than the examples from the mainland, and the light tip and dark 
subterminal bar on the tail slightly more pronounced ; but this may be an 
individual characteristic. 
Then of Acanthiza magnirostris he added : “ This is a well-marked insular 
form. Besides having the bill stouter and longer than in Acanthiza diemen- 
ensis , the coloration of the under-surface is darker than in that species. The 
wing is likewise f of an inch longer, and the tarsus stouter.” 
Simultaneously North in the Austr. Mus. Spec. Gat. No. 1 ., Vol. I., 
admitted Acanthiza ewingii as a valid species, writing: “has a distinctly longer 
tail and tarsus, darker upper-surface and throat ; abdomen and flanks dull 
or dusky greenish-olive, of which the latter parts are pale fulvous in Acanthiza 
diemenensis. The forehead too is light rufous and has not the scaled appearance 
of its ally ; the primary-coverts and spurious wing are blackish and the basal 
portion of the outer webs of most of the primaries are light rufescent-olive ; 
is found through the humid mountain ranges of Tasmania.” 
At the same time he described two new species, one from Dubbo, New 
South Wales, separated from the South Australian pyrrhopygia on account 
of the white under tail-coverts, etc., under the name Acanthiza albiventrisf the 
other from Kangaroo Island as Acanthiza zietzi on account of its greyer darker 
upper-surface and darker under-surface, etc., as compared with Acanthiza pusilla. 
The next year De Vis described as a new species the Bellenden Ker bird, 
as Acanthiza hatherina. 
Overlooking North’s description of the Kangaroo Island form, A. G. 
Campbell named the bird Acanthiza halmaturina, writing: “ There is a constant 
difference between the island form and that of the] mainland. The mantle is 
blackish, and not brownish- olive. The legs are black, and not brownish- 
black. The throat markings are heavier, while the forehead feathers at their 
bases are fawn-coloured and not rufous. Indeed, though it lacks the white 
tips to the tail-feathers, this island form approaches nearer Acanthiza apicalis 
of Western Australia than it does to Acanthiza pusilla of Victoria. Its
