The dentition is imperfect, it is possible to recognise the 
sockets of three incisors, one canine, one small premolar in advance 
of the two still present and two molars between these two teeth and 
the rising m3. 
The preniolars resemble the corresponding teeth of Thylacynus 
cynocephalns ; they are much longer than broad, sharp and pointed, 
the blade is curved slightly backwards and inwards, the posterior 
ledge cuspless. P4 is considerably larger than P3. 
The molar 1113 is slender and narrow ; it consists of a sharp, 
slightly incurved central cusp, a small anterior cusp and a less 
developed posterior one associated with which is a rudimentary 
postero-internal swelling. The posterior cusp is broader than the 
anterior one and has a subquadrate, not triangular outline. The 
two main secondary cusps are in contact with the central one on 
the outer surface. This tooth also more nearly approaches the 
type of the genus Thylacynus than that of the closely related 
Sarcophilus. 
On account of its general outline the jaw cannot be regarded 
as that of Sarcophilus, whilst the crowded nature of the teeth, which 
however may be regarded as an individual character in a young 
animal, distinguishes it from TAy/rtcy/zj/s, to which it has neverthe- 
less been ascribed on account of the numerous resemblances the 
fossil bears to a typical 'Fasmanian Tiger or Wolf, Thylacynus 
cynocephalns. 
A fragment of an atlas vertebra and an imperfect humerus of 
Thylacynus probably of the same animal were found associated with 
the mandible. A fragment of the skull with several cheek teeth in 
situvfa.s obtained in the Museum Cave in November, 1912.
