sign of «cf.?». Two species — possibly agreeing («cf. ?») with recent ones — seem 
to be the two unique forms hitherto known equally occurring in Holocene 
and Quarterly formations. 81 species are described (until 1914) being known 
up to now as exclusively Holocene forms. Finally two different remains 
from the New-World — perhaps specifically identic with eachother — belong 
to the somewhat doubtful genus Saniva*, mentioned here as an «appendix» 
of uncertain systematical position.

CHAPTER I. HISTORICAL AND CRITICAL SKETCH. 
As mentioned in the I st Part, Chapter I, dealing on Australian Vara- 
nidae, Sir R. Owen described in I860 a formidable lizard from the Con- 
damine River, Moreion Bay, Australia, under the name of Megalania prisca . 
This Lacertilian was compared by him with Var anus giganteus , until later
