are of moderate size — less than in Dasyurus : the 

 false molars are compressed and pointed : in the 

 upper jaw the foremost false molar is the smallest 

 and the posterior one the largest, but in the lower 

 jaw the posterior one is the smallest. The true 

 molars agree in form with those of Dast/urus. The 

 principal differences therefore, as regards the denti- 

 tion, between Dasynrus and Phascogale consists in 

 there being an extra false molar on each side of the 

 upper and under jaws, in the lateral arrangement of 

 the incisors and the large size of the anterior pair. 

 The Phascogales in all probability feed chiefly upon 

 insects.
