molar teeth ; the foremost of these are fractured. The whole 
series is 2 inches 4-J- lines in length ; the length of the hinder- 
most molar is 7} lines, and its width is 5^* lines. Tho longi¬ 
tudinal ridge in tho middle valley of tho tooth is well 
developed 
In tho same museum is the distal half of a right humerus, 
a lower end of a left femur, and a corresponding part of tho 
right femur, together with a small fragment of a shaft of a 
femur, which Professor Owen thinks probably belongs to the 
if . Titan. The above remaius were found in tho newer

tertiary deposits in the bed of the Condamine River: tho 
fragments upon which the author just mentioned founded the 
M. Titan were found in the caverns of Wellington Valley. 
Macropun Qoliaft (fossil) : Owen's MSS. 
All that is known of this species is a fragment of the right 
side of the upper jaw, containing two molar teeth, which is 
from the newer tertiary deposits of the Darling Downs, 
Australia. Judging from the size of tho teeth, this animal 
must have been even larger than either of the two preceding 
species, the two molars measuring together, in tho longi¬ 
tudinal direction, one inch and a half, and tho width of one 
of the molars being 7-t liues; they are proportionately 
broader, therefore, than in Macropus major. 
Besides these, Professor Owen characterises with a name a 
fourth fossil species—tho 
Macropus affinis (fossil) of the Descriptive Catalogue of 
the Fossil Organic Remains of Mammalia and Aves, 
contained in the Museum of the Royal College of 
Surgeons, p. 328. 
It is founded upon a “ portion of the left ramus of the 
lower jaw of a Kangaroo, with the penultimate and antepenul-
