Materials and methods
Besides the Thai National History Museum,
the other unpublished material
presented here was deposited in the Chulalongkorn
University Museum of Zoology
(Bangkok), at the Banlatwitthaya
School (Ban Lat) and at the Royal Belgian
Institute for Natural Sciences (Brussels).
Body measurements were made to
the nearest millimeter. Paired meristic
characters are given in the left/right order.
Snake ventral scales were counted
according to Dowling’s (1951) method.
The terminal tail scute is not included in
the subcaudal count. The numbers of dorsal
scale rows are given respectively at
one head length behind head, at midbody
(above the ventral corresponding to half
of the total number of ventrals), and at
one head length before vent.
