from its more ponderous contemporary. In the conformation of the posterior 
moiety of the mandible, that of the condyle excepted, it indeed resembles Diprotodon 
rather closely ; the position of the dental foramen in the two is almost identical, and 
the chief difference is the relatiVely greater development of the alar expansion in the 
newer genus ” 
the premnlars are described in general terms as simple unilobate teeth ; the 
upper one subiriangular in section, with the siibcentral conical cusps longitudinally 
constricted towards the apex, the constriction being still seen in a contraction of the 
dentinal band, as it traverses obliquely the longitudinal axis of the tooth. The lower 
premolar is structurally the same as in N’ototherimn, a.% identified by Owen, therefore 
the upper one of Nototheriim should not differ Mudely from that of the present genus. 
In bis last communication, Mr. De Vis has wisely changed the name from 
Owenia to 'Euoioenia, the former having been preoccupied no less than three times — in 
1847 by Presch for a genus of Cephalopoda; in 1853 by Kollicker for a Coelenterate, 
and, according to Count Marschall, by otie of the Agassiz in i860 for a Ctenophore.

Ohs. A second species founded on “ the inferior moiety of the articulating limb 
with the dentary limb of the left side in natural conjunction with the anterior half of the 
dentary limb of the right side, all the teeth of the parts preserved being in place except 
m. of the left side.” 
This fossil represents a very much more robust animal than B. grata, with a lower 
symphysial gradient, a parabolic instead of an angular inferior contour, and compressed 
rather than rotund incisors.

Obs. The anthral end of a right scapula has been referred to the genus Phalanger 
{Cuseus) under the above name, the Author remarking that it “ brings us into nearer 
contemplation of the recent genus Cuseus than was permitted to us by Arehizonurus." 
Its size was about equal to that of the last-named genus, and its nearest living ally is 
Phalanger {Cuseus) orienfalis, a, New Hebridean species. Touching the size of this 
extinct “ Possum,” the Author remarks—” The greatest breadth of the glenoid fossa in 
the fossil is sixfold that of P. Archeri ; its length has nearly the same proportion. P. 
Archevi is 310 mm. in length, sine cauda, and weighs about four pounds. Arehizonurus 
may, therefore, be estimated to have been about six feet in length, and 850 lb. in 
weight.”
