West. Aust . Mus ., 8: 405 . Type Locality: Australia , Western Australia , Pilbara Dist., East Hammersley Range, West Angelas Mine Site ( Kitchener, 1980 , provided additional information). Vernacular Names: Western Pebble-mound Mouse . Distribution: Australia , NW Western Australia ; extant specimens known only from Pilbara Dist. (Kitchener, 1985:216), but distribution of pebble mounds indicates range once extended through Gascoyne to Murchison Dist. with S limit near Mileura, N limit the Great Sandy Desert, and E limit the Gibson Desert ( Dunlop and Pound, 1981 ; Start and Kitchener, 1995 ). Conservation: IUCN – Lower Risk (lc). Discussion: This species builds pebble mounds and is sympatric with P. hermannsburgensis ( Kitchener, 1980 ) , which does not construct such mounds ( Dunlop and Pound, 1981 ), but phylogenetically most closely allied to P. johnsoni , another species that constructs pebble mounds (Kitchener, 1985). The use of pebble mounds as indicators of the presence of P. chapmani is documented by Anstee (1996) . Reviewed by Start and Kitchener (1995) .
