There are 280-315 ventral scales, an undivided anal plate, and 40-45 mostly single subcaudal scales.
12.
The ventrals are 146-161 in count; the anal scale is entire, with 19-27 paired subcaudal scales.
13.
The subcaudal scales are single or paired in each row, numbering 83 to 96 in males and 77 to 98 in females.
14.
The scalation includes 23 rows of dorsal scales at midbody, 188-196 ventral scales and 53-66 mostly paired subcaudal scales.
15.
The probe is marked at the point where it stops, removed, and compared to the subcaudal depth by laying it alongside the scales.
16.
There are 135-149 ventral scales, and 30-44 mostly paired subcaudal scales . 95 % of all specimens have 7 supralabial scales.
17.
Scalation includes 19 rows of dorsal scales at midbody, 159 ventral scales, 42 subcaudal scales and 10 supralabial scales, the third being the largest.
18.
The scalation includes 7 supralabial scales, 23 rows of keeled dorsal scales at midbody, 149-165 ventral scales, and 32-48 subcaudal scales.
19.
The subcaudal gland secretes a musky-smelling, cream-coloured fatty substance, while the anal glands secrete a stronger-smelling, yellowish-brown fluid.
20.
Males have from 65 to 89 subcaudal scutes ( average 76 ), with the tail from 23 % to 34 % of the snake's total length.
