Mr. Eilhol did not even note whether this femur is represented in natu¬ 
ral size or not ; if this were the case, and if my supposition — not 
statement — according to which the mentioned femur was justly 
determined by Eilhol as that of F. Cayluxi , were to prove right, the 
size of this species would be equal to that of an at least full-grown spe¬ 
cimen of V. griseus (a smaller individual is figured on Text fig. 2) or 
a smaller individual of F. salvator Latjr. 
Regarding the vertebrae (Textfig. 8) I should like to observe 
that I am unable to share in Mr. Re Stefanos opinion (op. cit, p. 411), 
according to which these appear to represent an intermediate state bet-

ween the M e g a la nia n-type and the oblong one observable in F. benga- 
lensis Daud. On the contrary, the vertebrae of F. Cayluxi are of a typical 
Varano id shape, whilst Megalania with its large, stout vertebrae 
bearing zygosphen and zygantrum, and provided with a very 
narrow ne ural canal, belongs, according to my opinion, to a separate 
systematical unity, for which I establish the family Megalanidae.
