1. A humerus is recorded 
by de Vis, though undescribed 
and unfigured ; following measure¬ 
ments are nevertheless given by him 
(on p. 96) : 
Length from radial condyle to 
tuberosity inclusive: 170 mm. 
Breadth at distal end : 106 mm. 
Breadth of shaft : 82 mm. 
This fossil is stated by de Vis 
(p. 96) to be «approximately» «3 times 
as long and 4% times as broad as 
that of V. varius ». 
2. -Ü Ina. This bone was figur¬ 
ed on the Plate accompanying Mr. 
de Vis’ article, and the reproduction 
of this drawing is here given in 
Textfig.37. The description is surpri¬ 
singly much more exhaustive than 
that of any other fossil dealt with 
by Mr. de Vis in his paper in 
question. As the figure proves some¬ 
what vague, I simply cite Mr. de 
Vis (op. cit. p. 94 — 96), without 
however affirming.or re¬ 
futing any of his respec¬ 
tive statements: 
«As to the ulna, we have in 
the form of its distal end a safe guide 
to the family to which it pertains. 
Oblcngo-clavate in shape in Austra¬ 
lian, and presumably in other lizards, 
this part of the bone is in the Gecko - 
nidae, Agamidae, and Scincidae 
merely a little modified by a flat¬ 
tening of its ulnar side, which 
scarcely affects the oval form of 
its articulating surface. In certain
