As seen in the part containing the criticism of European Varanidae, 
no positive fact can practically be established from the fragment. The 
bone itself is massive, the trochlea well developed, the eminentia capitata 
presents itself under the shape of a ball projecting to such an extent as I have 
not yet had opportunity to observe in Varanus . (Text-fig 18.) The epicondylus 
radialis forms a small prominence, whilst epicondylus ulnaris is not vi¬ 
sible on the drawing. Canalis nervi radialis is well developed. Compared 
with the humerus of other Varanus a difference lies principally in the fact

of the bone being stouter, in dorso-ventral direction less compressed, and 
the eminentia capitata remarkably well developed ; regarding the epicon¬ 
dylus ulnaris the most striking feature is its absence on the drawing. I am 
almost convinced of this humerus not belonging to the genus Varanus and its 
reference to the family Varanidae seems somewhat improbable. As how¬ 
ever no special features indicate as yet its position in the system and 
considering some affinities to Varanus I propose for it the generic desig¬ 
nation of Varanus ?. As to other particulars 1 refer to the critical part 
developing the subject. 
Habitat: Rheims (France).

Of these remains we have not even figures at our disposal and Hof¬ 
mann’s article containing neither description nor determination, this 
form is yet more problematic than the former. I must for this reason define 
Nopcsa’s denomination of « Varanus sp.» as most premature.
