Ohs. The shape and proportions of the molars seen in the living examples of 
this species, says Prof. Owen, are closely preserved in the fossil forms. J he researches 
of Mr. C. W. De Vis * amongst the Darling Downs Phascolomydro have rendered it 
exceedingly doubtful if this spccit^s is represented in Ihe ossiferous deposits of that 
district, the remains hitherto asciabed to P. plaiyrhinus being in all probability those 
of P. Mitclielli.

Ohs. The critical examinatiou of the Darling Downs fossil AVombat remains, 
already referred to, has led Mr. De Vis to the conclusion that this supposed species has 
no existence. He remarks f— “ H. Thomsoni, Ow., is an extremely doubtful species, 
uniquely represented, and dependent for its validity upon a single character, the. 
backivard extension of the symphasis, a character which varies with age 
P. Thomsoni should, therefore, be expunged from our lists.”

Ohs. Established by Mr. De Vis for a W ombat distinguished by the narrowness 
of its teeth, “which are intermediate in breadth between those of P. parvus and 
P. Mitclielli, though serially as long or longer than in the latter species. ^ As a marked 
reduction in the widtli of the teeth has not been noted in the descriptions of known 
species, and as the teeth in all the mandililes of P. MitchelU are appreciably the^samo 
in width, I must perforce regard this narrow-toothed wombat as a new species.” A 
humerus' and a tibia are also referred to P. angustidens. The animal is supposed to have 
been equal in size to P. MitchelU, but more delicate in structure.
