  2. Ventrals: The ventral scales are smooth and shiny, and the number of ventrals varies between 225-245.
  3. Subcaudals: The subcaudals are paired, and the number of subcaudals varies between 60-85.
  4. Anal Plate: The anal plate is divided.
  5. Head Scales: The head of the False Cobra is distinct, and the head scales are small and smooth. It has a single large supraocular scale, and a pair of large postocular scales.
  6. Eye Scales: The snake has large eyes with round pupils. The eye scales are small, with a single preocular and two postocular scales.
  7. Other Scales: The snake has 8-9 upper labials, with the third and fourth contacting the eye. It also has 10-11 lower labials.

Overall, False Cobra has a sleek and slender appearance with a distinct head and unique scalation pattern. The weakly keeled dorsal scales and large supraocular scale can help identify the species. The number of scales may vary slightly between individuals, but the overall pattern remains consistent.
