Ohs. A corresponding but smaller species of Wallaroo than the last. The name 
was also founded on the left mandibular ramus. Mr. Lydekker refers this to the living 
Macropus 'Farryi, Bennett.*

Ohs. Portions of jaws were described by Sir R. Owen, under this name, without 
assigning to them any definite locality. He considers that these remains deviate less 
from the type of the bilophodont Macropodidm than those of Frocoptodon, some of 
which, F. QoUah, for example, were of larger bulk. The entire skull would probably 
measure about sixteen inches in length. 
Mr. De Vis has described a portion of the jaw and dentition, since the appearance 
of Owen’s “ Extinct Mammals of Australia.” He considers F. azael to have been a 
true saltigrade of Macropodoid type.

Ohs. This name was applied by Sir R. Owen to two extinct species of 
Macropodid® in which the massiveness of the mandible was greatly in excess of the 
teeth it supported.

Ohs. A portion of right mandibular ramus indicated to Prof. Owen, by the size 
of the teeth and the jaw itself, a Kangaroo exceeding in size the Macropus titan. Mr. 
Lydekker refers this species to Macropus, and unites with it Leptosiagon gracilis, Owen.
