For want of original material and obliged thus to rely upon descrip¬ 
tions and figures — I cannot naturally enlarge upon a detailed characteri¬ 
zation of this species, as regards which I therefore merely allude to the 
literature above mentioned, as well as to what has been said above regarding

logical characters will however be referred to in treating of V. Hof manni. 
All I shall notice here is that among the fossil Monitors of Europe 
yet known, V. Cayluxi Filh. was one of the smaller sized forms, hardly 
exceeding the size of the recent V. griseus which approaches or slightly 
surpasses one metre in length. The femur represented by Filhol (op. cit.) 
as that of V. Cayluxi (and referred by Lydekker to Placosaurus) seems 
to indicate however a somewhat larger size (Textfig. 1); unfortunately
