REVISION OP AUSTRALIAN JERBOA MICE 
Readily distinguishable from all other species I have seen by 
the wholly white ventral fur. 
Notomys sturti Thos. 
Notomys sturti Thomas, Ann. Mag. Nat. Hist. (9), VIII, p. 537, 1921. 
Thomas’ description is as follows : "A long-tailed species, rather smaller 
than longicaudatus. Proportions about as in longicaudatus, though the feet 
are relatively larger. Colour apparently about as in that species, but the only 
specimen has had the distal part of the fur singed off, so that the exact shade 
cannot be described. Feet very slender. 
“Skull apparently similar to that of longicaudatus, but smaller in all 
dimensions. There is, however, no evidence as to the size of the bullae. 
“Habitat. — Interior of New South Wales in the Lower Darling region. 
Type ‘captured in the Coonbaralba Range about 85 miles from Laidley’s 
Ponds’.” 
Type. — In British Museum. 
I have not seen this specimen. It appears to be closely 
allied to longicaudatus, differing only by its slender feet, and 
therefore possibly should be placed in the genus Podanomalus. 
Notomys mordax Thomas. 
Notomys mordax Thomas, Ann. Mag. Nat. Hist. (9), IX, p. 317, 1922. 
Thomas based this species on a skull as follows : “Size about as in 
N gouldi, but the general build stouter throughout. External characters 
unknown. Skull broad, strongly built, with widely open anteorbital foramina 
and broad frontal region. Interorbital space comparatively broad. Palatal 
foramina long, well open, extending back past the anterior root of M. 1 Meso- 
pterygoid fossa fairly broad, but not specially broadened anteriorly, its sides 
practically parallel. Bullae rather small for the bulk of the animal, though 
slightly larger than in gbuldi ; conspicuously smaller than in the large 
longicaudatus. 
“Teeth large and heavy. Incisors orthodont, unusually broad and strong, 
as broad but not as deep as in longicaudatus, flatter and less bevelled in front. 
“Habitat. Darling Downs, S. Queensland.” 
Type (Skull).— In British Museum. 
I have not seen this skull. 
Genus PODANOMALUS Waite. 
Podanomalus Waite, Proc. Roy. Soc. Viet., X, p. 117, 1898. 
General characters murine. Differs from Notomys mainly by the absence 
of a eular glandular area, and by the presence, in the male animal only, of an 
oval, slightly swollen pre-sternal gland directly between the forelegs.
