The morphology of this species which is clearly distinguishable from 
V. Cayluxi, could be examined only so far as the respective descriptions 
and drawings- enabled me to do so, closer details must therefore be 
omitte’d. As regards F. Haf manni’ s connexion with F. Cayluxi, from the 
point of view of structural characteristics/ exact differences can hardly 
be stated from the photographs at my disposition. For does De Stefano’^ 
work contain any measurements in reference to F. Cayluxi either, from 
which the proportions of certain parts of the vertebrae might be estimated 
in view of establishing the precise value of morphological characters. It 
seems however that Varanus Hofiiianni must have been somewhat larger, 
the anterior part of its dorsal vertebrae suddenly widening and when reaching 
the vicinity of the condyle becoming suddenly narrower, thus.-presenting 
on the whole, a cuneiform aspect ; the ball is b r o a d 1 y rounde d 
and, correspondingly, the cup describes a wide ellipsis, whilst in 
F . Cayluxi the centre of the vertebra seems to contract already after
