its «average» especially, decidedly smaller than the fossil form to 
which it has been compared. 
The tibia, referred to by de Vis under the same specific name as 
the humerus, is described by him (op. cit. p. 99) as follows: «... the tibia 
represents an individual nearly one-half as large again — the difference, 
though considerable, is not of it self sufficient to warrant a distinction of 
species. Structurally, the tibia is in all respects an accurate forecast of the 
bone in recent species. The following specific characters are noticeable: 
the head less elongate transversely — the depth of the epiphysis on the 
tibial side much greater — the intercondylar notch wider and shallower. 
Like the humerus, it comprises features of two or more living species - 
a concave facet on the edge of the ectepicondylar tuberosity close to the 
procneminal tuberosity for the reception of the head of the fibula, faintly 
seen in V. gouldii, but not in varius, is quite distinct in the fossil, which, 
on the other hand, is more nearly approached in varius by the prominence 
of the ridge for muscular insertion which on either side descend from the 
condylar margins.» As was remarked, no figure is added to this description. 
This is all the information we possess about this fossil Monito r, 
which might be, as alluded to at the beginning of this description, a« mix¬ 
ed species», including perhaps partially a new, yet undescribed form, 
or completely representing an already described species — a possibility 
expressed by the term «hom. inc.» The systematical knowledge of this 
«species» is therefore, — as also that regarding the remains called «Varanus 
dirus », — most unsatisf actor y, both «speci es» ne-edi n g 
a thorough revision to establish their position in 
the System.

1 The fragmentary state of the remains not only infers a doubtful determination 
of family and genus, but even does not exclude specific agreement with some species 
already derc ubed, for which reason I alsó use the sign «hom. ine.».
