Pseudomys higginsi (Trouessart, 1897) . Cat. Mamm. Viv. Foss., 1:473.

TYPE LOCALITY: Australia, Tasmania, Kentishbury .

DISTRIBUTION: Australia; extant population known only from Tasmania; represented on mainland in Victoria and E New South Wales by Late Pleistocene samples (Wakefield, 1972b).

SYNONYMS: australiensis, leucopus (of Higgins and Petterd, 1881, not Rafinesque, 1818).

COMMENTS: Spermatozoal morphology (Breed, 1983) and electrophoretic data (Baverstock et al., 1981) placed P. higginsi with most other species of Pseudomys, but phallic anatomy (Lidicker and Brylski, 1987) clustered P. higginsi with P. australis, P. gouldii, and P. nanus . Wakefield (1972b) described australiensis as a subspecies based on Late Pleistocene fossils.
