MURIDAE RECORDED FROM VICTORIA 
General colour tawny-olive, darker on the mid-dorsal line. Dorsal fur 
(14 mm.) slate for a little more than half length, then tawny with dark tips, 
the latter becoming more pronounced at the hinder part of the body. Sides 
of body lighter, line of demarcation between dorsal and ventral colouration 
fairly sharp. Ventral fur basally grey for a little more than half length, with 
white tips. Head as body; cheeks lighter, upper lip white. Ears long, tips 
bluntly pointed ; outer surface sparsely covered with dark brown hairs, inner 
surface with silvery adpressed hairs. Gular glandular area well defined by 
thick, silky, white hair. Tail brown above, white below to the tip; hairs of 
tip much lengthened. Manus and pes silvery-white. Pes long and narrow, 
with four pads, though in some specimens the hallucal pad is not well defined. 
Skull. — Comparatively large for the size of the animal. Smooth and 
rounded. Anterior edge of zygomatic plate deeply concave with a projecting 
point above. 
Teeth. — Incisors slender. Molars with no anterio-internal cusp. 
Dimension of Skin. — Head and body, 112 mm.; tail, 148 mm.; hind foot, 
36 mm. ; ear, 23 5 mm. 
Dimensions of Skull. — Back of parietals to tip of nasals, 27 mm. ; nasals, 
10 5 X 3 mm.; interorbital breadth, 5 mm.; palate length, 14 mm.; breadth 
inside M 2 , 3 3 mm.; breadth outside M 2 , 6- 3 mm.; palatal foramina, 5 5 
mm. ; diastema, 7 mm. ; upper molars, 5 mm. 
Type Locality. — Junction of Murray and Murrumbidgee Rivers. 
No details of the habits of this species have been preserved, 
but allied forms construct burrows in which they make grass 
nests in typical murine fashion.

This form of Mitchell’s Jerboa Mouse is probably still liv- 
ing in north-western Victoria. It is greyer in colour, has 
longer fur, and slightly longer feet than the typical form. 
General colour between avellaneus and wood-brown, but darkened on the 
dorsal surface by a grizzling of dark-tipped hairs. Dorsal fur (18 mm.) slate 
for two-thirds of its length, then pallid with dark tips. Sides of body lighter, 
with less demarcation between dorsal and ventral colouration than in typical 
form. Ventral fur grey for less than half its length, tipped with white. Head 
as body; cheeks lighter, upper lip white. Mysticial vibrissae very long 
(55 mm.) ; dark-brown with lighter tips. Ear long, more truly oval than 
in typical mitchelli ; clothed on outer surface with hair same colour as body. 
Gular glandular area as in mitchelli. Tail greyish-brown above, white below ; 
hairs of tip lengthened. Manus and pes white. Pes a little longer and 
stouter than in mitchelli. Four pads. 
Skull and Teeth. — Similar to those of typical form. 
Dimensions of Skin. — Head and body, 107 mm. ; tail, 145 mm. ; hind foot, 
39 mm. ; ear, 26 mm.
