PART III MAMMALS by N. L. McKENZIEI, W. K. YOUNGSONI, A. A. BURBIDGEI and A. CHAPMAN'. INTRODUCTION Gibson Desert Nature Reserve-Hairs identified in dingo scats. This paper is based on information collectedduring Rangeswith mulga (l.l); breakawaysand stony hills visits to four areas in arid Western Australia (see with mulga(3.5). McKenzie, this publication). All mammals collected have been lodged in the WesternAustralian Museum with accessionnumbers: M14384-14425(November Petrogale sp. 1975collection), M14618 14676(March 1976collection).
