the upper and lower incisors of Sceparnodon are tnown, and, consequently, that 
Sceparnodon is not a synonym of Phascolonus.” There is much to he said for the hold 
conception given when defining the Tamily Nototherida) — viz., “ Probability is also in 
favour of Sceparnodon proving to belong to this family.”* 
The geographical range of Sceparnodon is a wide one, as teeth have been found 
in the vicinity of Lake Eyre, South Australia ; and in addition to the Queensland 
locality a number have been found in the rich bone deposit of Myall Creek, near 
Bingara, N. S. Wales, by Mr. Charles Cullen, Collector to the G-eological Survey 
of N. S. Wales.

Ois. A portion of a skull, consisting of the parietal and upper part of the 
occipital bones of a non-marsupial animal, has been described by Mr. De Vis, and com- 
pared to the corresponding portions of a Dugong. 
The chief difference between the fossil and the skull of the Dugong consists in 
a shallower temporal fossa and feebler muscles for working the jaws. 
A mould taken from the interior surface of these bones has enabled the Author 
to study the brain characters with much success. 
The brain was clearly of inferior development to those of existing Sirenians, 
“ and a smoothness of skull indicatory of feebler masticating power, may have been 
the co-adaptation of the softer vegetation and less perilous condition of life enjoyed by 
a Sirenian tenant of fresh waters.”

Ohs. The occurrence of various peculiar teeth in the Post-Tertiary Beds of 
Darling Downs has led Mr. C. . De Vis to suggest the former presence in Australia 
of a swine-like animal, more nearly allied to the Peccary {Bicotyles) than to the true 
Pigs. The teeth so determined are a quinque-tuberculate tooth of bunodont type, of 
the general shape of the last lower molar of Bicotyles torqiiatus, Cuv. ; a middle lower
