WHITE-BELLIED PHASCOGALE. -i 1 7 
Mr. MacLeay's original description appeared in the Annals 
and Magazine of Natural History for December, 1841, 
(vol. viii. p. 242), and is drawn up from a figure seleoted 
from a number of drawings made by Mr. Stuart (a surgeon 
in the army), combined with some notes by the same 
gentleman. From these it appeared the animal agreed with 
Phascogale generally, but was remarkable for the possession 
of but six incisors in the upper jaw, and thus afforded an 
exception to the dental formula of other carnivorous or 
insectivorous Marsupialia. Subsequently, however, Mr. Mac- 
Leay had an opportunity of examining the skeleton of the 
animal in question, and discovered the true dental formula to 
be as in Phascogale 1 . The animal, however, differs, Mr. 
MacLeay observes, “ in the three lateral incisors of the upper 
jaw being of equal size, and also in the pseudomolars being 
all of equal size.”

Grey; hinder part of back tinted with rusty brown : under parts 
white : feet dusky white; tail dusky above and beneath, but 
blackish at the apex; ears rather large, and sparingly clothed, 
for the most part, with minute pale hairs. 
This animal so greatly resembles the Phascogale flavipes 
in its proportions, as well as in the structure of its skull and 
teeth, that it is with considerable hesitation I describe it as
