applying the proportions existing between vertebrae and jaws in Varanus 
in somewhat the same manner to Megalania, we shall find that the M e ga¬ 
la n i a n dentary described under the name of «Notiosaurus» corres¬ 
ponds in every r es pect to the rest of Megalanian remains ; 
the occipital fragment convinces us, in the same manner, of this fact, proving 
that Megalania was also one of the very large-sized but small- 
headed Reptilian forms often stated in Palaeontology, the modern 
survivers of which are representad by the Varamdae. 
Mr. de Vis’ supposition, according to which Notiosaurus could be 
eventually synonymized with Varanus (1. c.), # was already refuted in the 
I st Part’s systematical chapter (dealing with V. dirus horn. me.). Thus the 
following elements are described, resp. recorded, in Mr. de Vis’ 
publication as belonging to Megalania: 
1° Vertebrae ?(undescribed), 1 
2° Ribs (description and figure), 
8° Ulna (description and figure), 
4° Humerus (measurements, but undescribed), 
5° Scapula (undescribed), 
6° Fibula (undescribed), 
7° Pelvis (undescribed). 
Indeed we ought to know nearly the whole skeleton of this interesting 
fossil form, and it is very desirable that the numerous deficiencies arising 
from Mr. de Vis’ descriptions and figures should be filled up as soon as 
possible. 
In 1894 Mr. R. Etheridge jun. published a paper «On the Occurrence 
of Megalania (Owen) (sensu stricto) in South Australia» 2 in which he des¬ 
cribes and figures (Pl. I, Figs 1 —8) a dorsal vertebra of Megalania, 
whilst the second vertebra, determined by him as a lumbar-one (Pl. II, 
Figs. 1 -2), «does not belong to Megalania, but is a true Crocodilian 
vertebra». 3

gerous j aw“ mentioned only on p. 94 by de Vis ought to be regarded also 
as belonging to Megalania , as the course of the description and the treatement 
of the subject offers, in general, a series of nebulous and contradictory parts.
