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 premolars resemble the corresponding teeth of Thylacynns 
cynocephalus ; 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 p 3 . 
The molar m 3 is slender and narrow ; it consists of a sharp, 
slightly incurved central cusp, a small anterior cusp and a less 
developed posteiior 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 Thylacynns 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 chaiacter m a young 
animal, distinguishes it from Thylacynns, to which it has neverthe- 
less been ascribed on account of the numerous resemblances the 
fossil bears to a typical Tasmanian Tiger or Wolf, Thylacynns 
cynocephalus. 
A fragment of an atlas vertebra and an imperfect humerus of 
Thylacynns probably of the same animal were found associated with 
the mandible. A fragment of the skull with several cheek teeth m 
situ was obtained in the Museum Cave in November, 1912.
