RECORDS OF W.A. MUSEUM. 
which is some three or four miles south of the Mammoth Cave, 
discovered an unfamiliar skull lying uncovered upon a large talus 
of coarse sand and fragments of limestone and stalactite. 
When Mr. W. B. Alexander, M.A., of this Museum, visited 
the locality in October, 1912, he noticed the striking difference 
between this skull and those of known indigenous mammals of the 
district, and therefore made a rough sketch of the specimen, as he 
was unable to remove it from the Cave. This sketch was subse- 
quently shown to me and I was able to report that the remains 
were those of some species oi Sarcophilus. 
In November, 1912, I was instructed to proceed to the Caves 
in order to obtain this specimen and to collect, among other things, 
as many remains as possible from this and other Caves in the 
neighbourhood within the time at my disposal. 
Soon after my arrival in the area, the Bride’s Cave wa.s visited 
and the skull removed from its precarious position. A large 
amount of sand and debris in the vicinity of the discovery was 
carefully sifted and examined, with the result that a small fragment 
of the lower jaw, with a molar in situ and several limb bones, 
presumably of the same animal, are now' in the Museum Collection. 
The bones are all in a fragile state and are not at all mineral- 
ised, suggesting that the animal was entombed within compar- 
atively recent times. The bones adhere to the tongue as do those 
of the extinct Phascolomys hacketti from the Mammoth Cave, with 
which they may perhaps be considered contemporaneous. 
The skull is not quite perfect, the left zygomatic process and 
the left auditory bulla are damaged, and the incisors and canines 
wanting. 
An interesting feature in connection with this specimen is the 
abnormal outline of some of the bones of the nasal region ; the left 
and right nasals and the right maxilla and premaxilla being the 
bones affected. Apparently at seme period of the animal’s life the 
bones on the right side of the muzzle were crushed and broken, 
parts of the right nasal being lost. In consequence of nature's 
attempt to repair the damage, a secondary growth of the maxilla 
extends to the median line of the skull, thus separating the anterior 
and posterior portions of the broken nasal and confining the area of 
the upper extension of the premaxilla, a detached piece of which 
seems to occupy the position of a lost fragment of the nasal.
