Hypsiprymnus.

(VI.a.) Figure 3 Plate 48. Part of the right ramus of the lower jaw, exhibiting a corresponding stage of dentition.

Observation. This species is rather larger than any of the three species with the crania of which I have had the opportunity of comparing them: there is no evidence that it agrees with any existing species.

GENUS PHALANGISTA.

(VII.) Cranium, coated with stalactite.

(VII.a.) Part of right ramus, with spurious and 2nd molar.

(VII.b.) Right ramus, lower jaw.

Observation. The two latter specimens disagree with Phalangista vulpina in having the spurious molar of relatively smaller size, and the 2nd molar narrower: the symphysis of the lower jaw is also one line deeper in the fossil. As the two latter specimens agree in size with the cranium, they probably are all parts of the same species, of which there is no proof that it corresponds with any existing species. But a comparison of the fossils with the bones of these species (which are much wanted in our osteological collections) is obviously necessary to establish the important fact of the specific difference or otherwise of the extinct Phalanger.

GENUS PHASCOLOMYS.
