Tail prehensile. 
The number of the teeth in the different species of Pha¬ 
langer varies, but the differences observable are not important, 
since they arise from the appearance or non-appearance of 
certain small teeth, situated between the molars and incisors, 
which ore not always constant even in the same individual 
Phalanger; one of these teeth will sometimes be found, for 
instance, on one side of the jaw, and not on the other: all 
the species, however (with the exception of those belonging to 
the section Dromicia ), possess four true molar teeth on each 
side of each jaw, and each of the series is preceded by a pre¬ 
molar, which is in contact with the true molars : in front of 
tliis, and more or less widely separated, is a second premolar 
in the upper jaw, and which, in most species, is a well- 
developed tooth, having the elongate conical form of a 
canine : in front of this, again, is a moderately well-developed 
canine tooth, which is usually situated more forward, with 
relation to the intermaxillary suture, than in most other qua¬ 
drupeds ; in most species the tooth is intersected by the line 
of the suture in question, and sometimes the whole canine is 
situated in front of the suture— that is to say, the visible 
portion of the tooth, for I suspect it will always be foimd to 
have its root in the superior maxillary bone. Lastly, there 
are six incisors in the upper jaw. In the lower jaw there are
