Table 1. Definitions of, and abbreviations used for, measurements, mensural ratios, and scale counts.

Symbol	Description
Measurements
A	Head length from snout to anterior dorsal margin of tympanum
B	Head width at maximum span of postorbital arch
C	Head depth at midpoint of orbit
D	Head–neck length from tip of snout to gular fold
E	Body length from gular fold to cloaca

G	Facial length from centre of nostril to anterior margin of orbit
H	Snout length from tip of snout to centre of nostril
TL	Total length
SVL	Snout to vent length
Mensural ratios
1	Relative tail to body length – F/ SVL
10	Relative head length to head width – A/B
11	Relative head length to head height – A/C
Scale counts

m	Scales around neck at anterior margin of gular fold
N	Rows of ventral scales from tip of snout to gular fold
P	Scales from rictus to rictus across dorsum of head
Q	Scales around tail base
R	Scales around tail counted at 1/3 of tail length from the base
DOR	Number of dorsal scale rows from the last occipital scale to a point dorsal to the posterior margin of the cloaca
