10 LÖNNBERG, RESULTS OF DR. E. MJÖBERG'S SWEDISH SCIENTIFIC EXPEDITIONS TO AUSTRALIA 1910—13. 
In its general appearance this minute Phascogale closely resembles Ph. ingrami 
THOMAS', and most especially this is the case with regard to the extreme flatness of 
its skull. It is, however, quite distinct from the species quoted, being still much 
smaller but with comparativelv longer tail. Ph. ingrami has according to THOMAS 
head and body measuring 80 mm., the tail 60, the hind foot 10, and the ear 9 mm. 
As the present specimen from Noonkambah is a fullgrown male with a comparatively 
large scrotum the difference in size does not permit identification. The same result 
is also obtained from the following cranial measurements.

The skull appears to resemble that of Ph. ingrami with regard to the posteri- 
orly well expanded nasals, flat interorbital region without ridges and obsolete occipital 
crests, but the interorbital portion of the skull is broader. Foramina incisiva (»>anterior 
palatine foramina») reach to the level of the anterior part of the canines. There are 
no vacuities on the posterior palate. Anterior portion of bulle larger than posterior 
as in Ph. ingrami. 
The premolars are subequal in size when seen from the side, and when seen 
from the surface the middle one, »p”», is rather larger than the last, »p'». This is 
a striking contrast to the corresponding condition in Ph. ingrami in which »p'» is 
»about twice the size of the subequal and median premolars» (THOMAS 1. c. p. 542.). 
In the lower jaw only two premolars are developed, the »secator» is thus ab- 
sent, and the posterior of the two present ps; is larger than the anterior p,. 
The fur is soft and close, with somewhat silky appearance. The general colour 
above is of a soft and warm brown, somewhat resembling some specimens of Mus sylva- 
ticus. This colour is produced by the buff of the outer parts of the hairs being 
sprinkled with the blackish tips of the same. On the sides of the head, above the 
eyes, behind the ears, and along the flanks near the line of demarcation towards the 
ventral side the buff is dominant. The concealed parts of the hairs above are slaty. 
Lower parts dirty white. Crown of the head like the back. Tail short-haired so that 
the scales are not concealed, pale brownish grey. Feet brownish white.
