systematical investigations will prove. However, as regards the Vara- 
nidoe — provided that the American Saniva would not prove to be 
Varanian Arldt’s data, as appreciable to-day, appear to rest upon a 
decidedly false basis, considering that the facts from which he 
concludes to the above mentioned statements, in reference to the Va - 
ranidae — the questionable Saniva excluded, — must be regarded 
as founded on a systematical error. This would naturally conduce to the 
irrelevancy of the numerous references to the N e a r c t i c origin or H o 1-

arctic extension of the Varanidae contained in Arldt’s otherwise 
practical and important work ; thus the family Varanidae. could then be 
considered as sprung from the K ænogea 1 , though only in a restricted 
sense, with exclusion of the New World. The question would, of course, take 
another aspect if the Saniva vertebrae happened not to be included in the 
A nguidae, but would be surely determinable as belonging to V aranidae, as 
Leidy, who first described this form, and lately Nopcsa, both presumed. 
In this case Fürbringer’s expression «altweltlich» would necessitate a mo¬ 
dification. Furthermore it is interesting to note that with the exception
