Ols. Of this animal the portions hitherto discovered consist of a deciduous 
molar, a femur, radius, and ulna. Mr. Do Vis remarks — “ In dentition the animal 
diverges considerably from Wototherium, more so from Biprotodo7i ; its divergence is 
towards the Macropodidee. In its long bones it approaches very closely to Biprotodon, 
possibly to Nototherium also. Its thigh-bone shows that it hardly departed from these 
in the structure and movements of its hind-quarters. It is, in short, a transition form.” 
The tooth is fourteen lines in length, ten and a-half lines in its anterior and 
nine lines in its posterior transverse diameter.

Ols. Mr. DeVis has lately drawn attention to the great divergence which 
exists amongst the various genera of Maeropodidas in the “ gluteal angle ” of the 
femur. “ By gluteal angle is meant the angle made with the long axis of the bone by 
a straight line touching the top of the trochanter and the summit of the head” of the 
bone in question. The value of this angle, adds Mr. De Vis, expresses the measure of 
the leaping ability of the animal. 
A femur lately discovered, having the very open gluteal angle of 77|°, has 
afforded this Author the opportunity of establishing the above genus, the loss of 
saltatory power consequent on this open angle quite precluding its reference to any of 
the more typical genera of Macropodidse. The femur of B. Falmeri was equal in size 
to that of Falorchestes azael, Owen, and not much inferior to Procoptodm goliah, 
Owen. The generic name has reference to the contracted gait of the animal.

Ois. Both genus and species are founded on a left mandibular ramus, which 
seems to indicate an animal allied to a gigantic Hgpsiprymnodon. Mr. De Vis remarks : — 
It would seem that the relations of the extinct animal are complex ; capriciously, as it 
were, its relic yields us glimpses of each of the three families so frequently named 
[i.e., PhalangeridsB, Pleopodidse, and Macropodidss] Though its affinity 
to Hgpsiprymnodon may be said to be paramount, it must be confessed that it is not so 
to any great extent.” 
In Triclis the lower incisor is followed by a tooth, small in size, but occupying 
the position of the so-called canine in the Phalangcridse. In Hypsipry7nnodon, on the 
other hand, this tooth is absent.
