^'°'i;ef J CAMl'BKLL. Xczc Sub-species of Tit-H'cirblcrs. 63 



We went on to The Great Lake, and in many j)laces I spotted 

 nests of J^>lack Alag^pies or Hill l>ell Mas^pies — ]'dy>{Strcpcra ar- 

 (jnta) built in the fine cider _<,mms ( Eucalyptus t/urt)iii, Hooker). 



On the way to I'.othwell lliere is a nest on a linih si)annin,i( the 

 main road. 



Before concludins^- I niii^lu mention thai the one jay (Strcpera 

 argiita) which tre(|uents The Steppes homestead hrouiijht a mate 

 this season, and when T was there T saw them with their family. 



New Sub-species of Tit- Warblers {Acanthizae) 



By A. G. CAMl'lJELL, J. P., R.A.O.U., Croydon, Victoria. 



While examining a long series of Acanthizcc to determine the 

 limits of certain species, I discovered that important geograi)hical 

 regions are unrepresented although distinct sub-species occur 

 therein. The following* offer good grounds for separation: — 



Acanthiza pusilia leeuwinensis. Sub. sp. nov. 



Upper surface dark brownish olive, tinged on rump with medal 

 bronze (dark orange citrine); frontal patch less marked than in 

 A.p.piisilla, but tawny to the base of feathers; forehead crescents 

 ochracecus tawny with dark spots beneath and dusky fringes, like 

 those of A. p. macularia; upper tail coverts and base of tail cinnamon 

 brown; throat white with black striations heavier than in A. p. pusilia ; 

 flanks tawny olive; under tail coverts cinnamon buff; tail with black 

 subterminal bar .3 inch wide, tips edged white on inner web; central 

 feathers with an obscure dark spot (rudimentary bar) near tip; 

 bill and legs bro-wn; basal half of lower mandible light; eyes red. 

 Length, 3.8 in.; bill, .35 in.; wing, 1.9 in.; tail, 1.7 in.; tarsus, .8 in. 



Type male (103) from the collection of the late A. W. Milligan, 

 and now in the Royal Australasian Oi-nithologists' Union's Collec- 

 tion, Melbourne. Taken 26/4/1911 at Wilson's Inlet, South West 

 Australia, by F. Lawson Whitlock, R.A.O.U., collector. 



Co-type female (253) in "H. L. White Collection,," National Mu- 

 seum, Melbourne. Similar to male, but tail tips more broadly marked 

 with white on four outer feathers; under tail coverts darker ochra- 

 ceous tawny; axillaries warm buff. Taken at Augusta, S.W. Aus- 

 tralia, 6/4/1919, by T. Carter, R.A.O.U., collector. 



I have seen similar skins from Irwin's Inlet, S.W. Australia. This 

 is an interesting link between the Acanthiza of eastern and western 

 Australia, and cannot be confused with Acanthiza apicalis. 



*As Acanthiza (Moiacilla) pusilia does not appear to have a defi- 

 nite type locality assigned to it, I hereby declare Port Jackson, New 

 South Wales, to be the type locality (see White, "Journal of Voyage 

 to New South Wales," p. 257, 1790). 



The same thing applies to Acanthiza nana, and I also declare Port 

 Jackson, New South Wales, the type locality (see Vigors and Hors- 

 field, "Trans. Linnajan Society, London," vol. xv., p. 226, 1827). 



In another article I propose to deal with the natural causes which 

 apparently affect the distribution of the Acanthizce. — A.G.C,
