THE WOMBAT. 
Phascolomys Hachetti, Sp. Nov. 
(Plates II. and III.) 
From a “blow hole” penetrating the rock upon which the 
main mass of the osseous deposit was situated, numerous bones and 
skulls of small marsupials were obtained, the largest being the 
remains of a wombat which had either perished in the hole, or had 
its body transported there before decay was so far advanced as to 
allow portions of the skeleton to become detached, for even the 
lower jaw, which is so easily lost, was present along with the other 
bones. 
This part of the deposit was connected with a thin layer 
overlying the main mass and is evidently of more recent age than the 
material which contained the bones of Dipvotodon and Nototherium. 
The nature of the hole and the way in which the sand and 
bones were cemented together, rendered the task of recovering the 
specimens a matter of the greatest difficulty, and in spite of the 
care taken, several bones are missing. Those portions of the 
skeleton which have been recognised up to the present time will be 
described in the following order : Cranium, mandible, vertebral 
column, sacrum, ribs, the pelvis, the fore limbs, and the hind limbs. 
The bones will be compared with the figures and descriptions in the 
works of reference available, and their differences and resemblances 
noted, particularly as the examination of the skull has revealed 
points of difference from the recognised phascolomine species.
