DASYURUS. 
433 
The teeth of the Dasyuri differ but little from those of the 
Pliascogales, which have been described in detail. The most 
striking difference consists in the reduced number of premolars, 
of which there is one less on each side of each jaw. The 
incisors form a continuous series in either jaw, the foremost 
pair of the upper jaw not being thrown outwards and forwards 
as in the Pliascogales; the incisors, moreover, in the Dasyuri 
are very nearly equal in size. With regard to the true molars, 
the cusps ore rather less sharply pointed than in the Pliasco- 
gales ; I can perceive no other difference in the molars 
of the species which I shall first describe ; in the Dasyuriis 
ursinus the teeth present some modifications which will be 
noticed when that animal comes under consideration. Some 
of the Dasyuri have no inner toe to the hind feet: we will 
commence with those which, like the Pliascogales, have a 
small, nailless, and thumb-like inner toe to the hind foot.
