Obs. The sectorial teeth of this species demonstrate the presence, during Post- 
Tertiary times, of a large Carnivore, the marsupial character of which is indicated by 
the name “Marsupial or Pouched Lion.” The dental formula is i. c. p. 
m. l:A=30.

Mr. C. W. De Vis has lately described* a femur, believed by him to be that of 
Tbylacoleo, from the Darling Downs. He remarks — “ The bone is in general form 
unlike any recent femur known to the Writer, inasmuch as it tapers gradually from 
the proximal end to the distal third-fifth, and is in its proximal moiety rather strongly 
curved, both inwards and outwards.” Again — “ The fossil resembles the femur 
of the Carnivore in the shortness and direction of the lesser trochanterian ridge, 
in the obliquity of the post trochanterian fossa, in the shape of the head, 
in that of the shaft anteriorly, and generally of the whole distal extremity. To 
this we may add that the backward curvature of tho shaft is found in the allied genus 
Dasyurus. On the other hand, it resembles the corresponding bone in Fhascolomys in the 
shape of the great trochanter exteriorly, in the prominence of the lesser trochantei’, in the 
insertion of the ligamentum teres, in the depth of the neck between the great trochanter 
and the head, and in the turgidity of the space between the fos.sa and the head. In brief, 
its proximal extremity, with prevailing characters of its own, has more of Phascolomys 
than of Sarcophilus in its composition, while its shaft and distal end show relation almost 
exclusively (as between these two) to Sarcophilus. But withal there are features of 
Macropus not to be overlooked ; the angle of articulation, the shape anteriorly and length 
of the outer condyle, the tumid quadratus insei'tion, and the extra- condylar groove. 
We may sum up the whole by saying that sarcophiline affinities are dominant, phas- 
colomine subordinate, macropine concomitant.”

Obs. Throughout this family I have, as far as possible, adopted the subdivisions 
proposed by Prof. Owen, and his references ; but, for the sake of convenience, the sub- 
genera are treated as genera. This does not altogether accord with Mr. Lydekker’s 
arrangement in tho British Museum “ Catalogue of Eossil Mammalia,” Part 5, where
