dental series coniplete, but nearly the whole of the ascending 
rami are missing ; the other is a similar, though somewhat less 
complete, fragment having lost, in addition to the ascending rami, 
that part of the symphysis in advance of the premolars, in which 
the incisors were implanted. 
Of these fragments it is sufficient, for the object of this com- 
munication, to state that they correspond pro tanto to Owen’s 
descriptions and they thus indicate a rather closer resemblance, 
on the whole, to the latifront than tothe platyrrhine species of 
living wombat. 
We must postpone our remarks upon the remainder of the 
skull until it shall have been more completely restored. 
Passing now to a brief notice of the bones of the appendicular 
skeleton, in which we shall dwell rather upon departures from 
than upon agreements with the phascolomydian type, we may 
say that they are without exception of an extraordinarily massive 
character, as will be more particularly indicated by the length 
and breadth dimensions to be subsequently given. 
SCAPULA. 
Length* (from tip of coracoid process to base at junction of 
spine, 295 mm.; the breadth owing to mutilation cannot be 
given. Length of glenoid cavity, 85 mm.; the breadth cannot be 
stated. 
Phascolomys latifrons:—Length of Scapula, 116 mm.; of 
glenoid cavity, 25 mm. 
In the one specimen of this bone which we possess there have 
been preserved the whole length of that portion of the body from 
which springs the spine, the greater part of the spine itself 
(exclusive of the acromion), the neck, glenoid cavity (somewhat 
damaged) and coracoid process. 
Such parts of this bone as permit of comparison reveal 
phascolomydian features, the chief noticeable difference being 
that, in the fossil, the coracoid process, on to the base of which 
the glenoid surface extends as it does in the wombat, is not as in 
the latter deflected in the direction of the subscapular fossa. 
HUMERUS. 
Maximum length, 238 mm.; maximum breadth (between 
epicondyles), 126 mm. 
Wombat :—Length, 105 mm.; breadth, 48 mm. 
*In each case the length given is the distance between the transverse 
parallels of the two extreme points. The breadth is that of the widest 
part of the bone, the position of which will be indicated. For comparison 
the corresponding measurements in a young but fully grown Phascolomys 
jatifrons will be also stated.
