i u s nasalis of intermaxillary is narrow, not incruste d, 
sts h i n d point wedged in between the ossa nasalia is thus well vi¬ 
sible. Ossa nasalia long, becoming more or less narrower towards 
their posterior part, they are but very feebly or not incrusted, their sutures 
are therefore clearly discernable. The roof of the skull is but 
feebly incrusted, some of the bones being thus more or less trans¬ 
parent in several places, especially so the II. and III. supra- 
ocularia, as well as the median and lateral parts of the os parietale and the 
ossa postfrontalia interna. In the older specimens parietal bone 
towards the processi parietales distinctly, in the some¬ 
what younger ones less clearly, defined by a crusta calcarea. 
The processi parietales form a large, moderately flat arch, 
between which a part of the membranous cranium may be seen ; 
the greatest part of the cranium ossaeum appears free, thus the 
supraoccipitalia’s two arch-like ridges continuing 
on the pleuroccipitalia, are widely separated from the edge of 
the parietal processes. Supraoccipital and parietal joining on a 
considerable extension. No well developed processus 
ascendens, this one is only markad by a minute elevation which appears 
still smaller than in Lacerta muralis Laur. (Pl. II. fig. 3.). Praefrontali a 1 
in their anterior part short and large, cuneiform, backwards bearing a long 
point nearly reaching the middle of the supraoculare II. Four distinct 
supraoculars; the first small, the third presenting a 
large fontanelle ( pars membranacea laminae supraciliaris ), 
which extends also somewhat to the hind part 
or border of the second; this fontanelle is pre¬ 
sent in all specimens of examined material, 
except some individuals from Coruna being 
senil or approaching the limit of senility, in 
which I found an entirely ossified lamina supra¬ 
ciliaris; 2 in younger individuals the fontanelle is larger. Regarding 
therefore the presence of this membranous part on the supraoculary bones, 
I think I may emit the supposition that the skull of var. Bocagei 
presents it still in adult specimens, the mem¬ 
brane in question appears however fully ossi¬ 
fied inbothsexes when the individuals approach 
the limit of senility (PL II. fig. 6.) ; this supposition might

2 I am nearly sure, that the other decapitated senil in the collection of the Hunga¬ 
rian National Museum also presented the portion in question as entirely ossified.
