I 80 LEGGE, Some Rectifications in Tasmanian Ornis. j" ^"?^ n 



this omission was probably owing to Dr. Sharpe having only 

 those examples in the national collection to judge from, which 

 were evidently belonging to the open-country form, A. die- 

 menensis , which is more easily procurable than the first species, 

 A. ewingi. Personally, I had shot the bird several times, but 

 had not preserved the skins ; and I omitted the species by over- 

 sight in my list. It is satisfactory that when attention was 

 drawn to this Acanthiza at the Congress, conclusive evidence 

 as to its existence should so soon have been forthcoming. There 

 is a specimen in the Museum among the birds in a small col- 

 lection recently acquired from a private source, and which came 

 from the New Norfolk district ;■ another was procured in the 

 gullies on Mt. Wellington by Mr. A. G. Campbell, and a comparison 

 of these examples with A. diemenensis furnishes the following 

 details : — 



A. ewingi. — The principal characteristics of this species at 

 once distinguished from A. diemenensis — the rufescent forehead, 

 the greater length of tarsus, and the dark " winglet " (at point 

 of wing). To these may well be added, as a marked feature, the 

 greater length of tail. Minor differences are — darker upper 

 surface in ewingi, darker throat, the dusky bases of the feather 

 showing more conspicuously than in the common species, the 

 fulvous edgings of the primaries, and the darker abdomen. 



Gould shows the dark winglet in his figure, and notes it in a 

 description, also the length of tarsus, which feature has been 

 evolved, no doubt, from the bird's mode of life in frequenting 

 undergrowth. 



The measurements of two specimens — one of ewingi and one 

 of diemenensis — from the same district (New Norfolk) are : — 

 A. ewingi: wing, 1.95; tail, 1.7; tarsus, 0.95. A. diemenensis : 

 wing, 1.93 ; tail, 1.59 ; tarsus, 0.75. 



This species has recently been procured by Mr. A. G. Campbell 

 on King Island and mentioned by him in his article (cf. vol. ii., 

 p. 207). 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. 



Acanthiza magnirostris (Campbell). 



This is a well-marked insular form. Besides having the bill 

 stouter and longer than in A. diemenensis, the colouration of 

 the under surface is darker than in that species. The wing is 

 likewise \ of an inch longer, and the tarsus stouter. 



MlCROPUS pacificus (Latham). 



This Swift was omitted from my revised " Systematic List " 

 of Tasmanian Birds, prepared for the A. A. A. Science Con- 

 gress two years ago. I observed several examples in a large
