852 DR.J.MURIE ON THE SPECIES OF PHASCOLOMYS. [ Dec. 12, 
These larger fossils are all marked as having been obtained from 
the post-pliocene deposits, Darling Downs, Australia, and were pre- 
sented to the National Collection, some by Sir Daniel Cooper, Bart., 
others by T. W. Isaacs, Esq. 
They are as yet undescribed ; but Prof. Owen, in his article on 
the “Osteology of the Marsupialia,’ Trans. Zool. Soc. vol. iil. 
p- 306 (1849), refers to similar specimens in the following terms :— 
‘“«I have recently obtained eyidence from the post-pliocene deposits 
of the district of Melbourne, through the kindness of my friend Dr. 
Hobson, of an extinct Wombat, a true Phascolomys, at least four 
times as large as either of the known existing species.” 
At a future time I may find opportunity to treat more fully upon 
the comparative differences of the remaining bones of the skeleton 
of the three animals, the skulls of which I have figured, and therein 
point out in detail the reasons for adopting Dr. Gray’s generic term 
Lasiorhinus (which, however, I am inclined only to use as subge- 
neric) to the animal known as the Broad-fronted Wombat of Owen, 
and the Hairy-nosed Wombat of Gould. 
But for the present I shall assume the distinction, and at this 
stage terminate by calling attention to what, from my short re- 
searches, I deem the proper specific classification, characters, and 
synonyms of the group. 
PHASCOLOMYID. 
1. P. wombat, Péron et Lesueur. 
Genus PHAscoLomys. 2. P. platyrhinus, Owen. 
3. P. magnus? (fossil). 
Subgenus Lasioruinus. 4. P. latifrons, Owen. 
I have not here included the fossil genus Diprotodon, previously 
classed in this group by Prof. Owen (Trans. Zool. Soc. vol. ii. 
p- 332), as I believe more recent observations tend rather to show 
its nearer affinity to the Kangaroos. 
Order MARSUPIALIA. 
Family PHascotomytp& (Owen, 1839). : 
P 2 Ee a: 
Characters.—Incisors 5; canines 33 premolars = ; molars a= 
24. Incisors scalpriform in both jaws; false and true molars with 
persistent pulp. Stomach outwardly simple, but containing within 
a special cardiac gland; ceecum short and wide, with a vermiform 
appendix. 
Genus Puascotomys (Geoffroy, 1803).
