As proved by the synopsis here given comprising recent and 
fossil representatives, 43 forms are known up to now as referable to the 
family Varanidae ; 41 belong to the genus Varanus, inhabiting the Old- 
World and Australia : amongst these 8 «species» only are fossil, from which 
4 species of established specific value, whilst the 4 others ought to be consi¬ 
dered as «homologitatis incertae» ; between the 4 distinct fossil species one 
must be regarded as «Incertae sedis», consequently merely as an «appendix» 
to Varanus (Varanidae); such an «Incertae sedis» form exists also between 
the 4 fossils mentioned as «horn, ine.», together with these a fragment of a 
not quite certain specific identity may be mentioned, thus denoted by the
