impelled and enabled it to swallow whole the bulkier creatures 
of its age, and thin their numbers to equilibrium point, its 
powerful fore-limbs would aid it chiefly in its attack on lifeless 
prey—with their support and help the jaws would rend the flesh 
and tear apart the tendons of the dead Diprotodon and Notothere 
as easily as those of its descendant the remains of the kangaroo 
and bullock. 
We may add that if the former conditions of life were 
as favourable to the numeric increase of Notiosaurus, and 
probably other such giants, as those at present in force are 
locally to Hydrosaurus and Monitor, human life in its pristine 
feebleness could hardly have made head against them. That 
man in any form was coeval with these great lizards is yet to be 
discovered ; but the fact of his universal friend, the dog, being 
then in the land is too suggestive to allow us to put the idea 
aside. Is it possible that the absence from these drifts of human 
remains is related to the frequency of those great carnivors ? 
Is it possible, also, that the legends of dragons and hydras are 
but echoes that have reached European shores of the struggles 
of naked heroes with their saurian foes in far away lands ?

Curiously enough the preceding notes were hardly penned 
when fortune favoured the writer with a tooth of the same age 
and probably of the same species as the one indicated by the 
humerus. It wasina medley of small bones and fragments form- 
ing part of the Museum Collectors’ gatherings during the last 
three weeks at Clifton, Darling Downs. Its opportune appear- 
ance is the more interesting in that it seems to strengthen one of 
the opinions formed respecting Notiosaurus. The teeth in Mon- 
itor, compared with those in Hydrosaurus, are broad and thick; 
the tooth of the latter is distinctly serrated on both edges, while 
in the Monitor tooth the fore-edge only is serrated, and that 
faintly. The outline of the tooth of the extinct lizard resembles 
that of Hydrosaurus, but it is proportionately thicker; its fore-
