FOSSIL VARANIDAE AND MEGALANIDAE. 
B89 
the 2 d edition of his «Grundriss d. vergi. Anatomie». However since no des¬ 
cription of the treated element is given, I am obliged to limit my in¬ 
vestigations to what is exhibited on Fig. 9 Pl. XIX of his publication (see 
Textfig. 8&). In this drawing the supraorbitale also shows great resemblance 
to that of F. griseus (see Textfig. 9). The proc. anterior (mihi) 
completely agrees in both species ; the proc. medialis (mihi) is however 
somewhat larger at its extremity and more bluntly rounded than in V. 
griseus. This difference might however be merely of an individual cha¬ 
racter. Proc. posterior (mihi) broken about in its middle region; 
basal half like in V. griseus. 
5. Uncertain skull-fragments. 
(Textfig. 86.) 
Under this collective term I refer to the mandibulary-fragments 
figured, though not described, nor even mentioned, in Weit- 
hofer’s publication. These fragments indicate a robust, large animal, 
corresponding in bulk to the dorsal vertebra described below. Consulting 
the figure (see Textfig. 8 b) these fragments appear to consist of the following 
elements : the coronoideum robust and stout ; a part of the strongly frac¬ 
tured angulare (or operculare?) ; in the posterior part two horizontally 
disjointed bones seem to represent the supraangulare and articulare, 
whilst the retroarticular process appears to be strongly damaged (par¬ 
tially wanting ?) ; owing to the considerably injured surface, the outlines 
of these disjointed elements — partially disfigured — are clearly enough 
exposed. It is natural that a just appreciation of the morphology of these 
bones could only be obtained by a careful preparation, disengaging them 
of the matrix in which they were embedded. 
6. Dentale. 
(Textfig. 10 & PI II, Figs. 3-4) 
The fossil from. Arene Candide (Italy) is also that of a dentary ; 
the figure published by Mr. N. Morelli is a rather primitive one, offering 
no clear idea of the remain’s morphological conditions. No description is 
added to it. I reproduce it on Textfig. 10. 
The Beremend (Hungary) remain is represented by a part of the hind 
portion of the bone, showing two teeth present at a slight distance from 
eachother. A striking feature in this fragment is the typical pleurodont
