MURIDAE RECORDED FROM VICTORIA 
71 
Genus PSEUDOMYS Gray 1832. 
Contains the Australian mice, the genus being restricted to 
Australia and Tasmania. The skull is slender and the brain- 
case rounded and without supraorbital ridges. In 1910 
O. Thomas divided the genus into four subgenera. 
Subgenus Pseudomys s.str. 
Size large. Skull flat or concave in posterior nasal region. 
Front edge of zygomatic plate concave, with projecting point 
above. Palatal foramina large. Molars high with heavy 
cusps; no anterior-internal cusp on M 1 (except as an unusual 
abnormality) . 
No example of this subgenus has been recorded from 
Victoria. 
Subgenus Thetomys. 
Size medium. Form of skull more normal. Front edge of 
zygomatic plate less concave ; without projecting point above. 
Palatal foramina long but not widely open. Molars less heavy 
with a distinct anterio-anternal cusp on M 1 .

Gould’s Mouse has not been recorded from Victoria since 
1857, when Blandowski secured several specimens. Unfortu- 
nately these were crushed, apparently soon after their 
preparation as skins, and are completely flattened. The skull 
of one specimen has been removed but is too fragmentary to 
reconstruct. Waterhouse’s original description is here some- 
what extended. 
A medium-sized mouse with close soft fur and a long slender pes. General 
colour tawny-olive. Dorsal fur (11 mm.) slate for a little more than half its 
length then ochraceous to the tip. The numerous long hairs are of two 
colours, some yellowish, some black to the base. The general effect is an 
etched appearance. Sides of body lighter with faint demarcation between 
the dorsal and ventral surfaces. Throat white, hairs white to base; chest 
and abdomen yellowish-white, hairs basally smoky-grey for about half their 
length. Head as body; cheeks lighter, upper lip white. Mystical vibrissae 
long ; brown with lighter tips. Ears fairly long and rather pointed ; sparsely 
clothed on outer surface with light-brown hair, inner surface naked except for
