According to Leviton (1964), the scalation includes 21 rows of dorsal scales at midbody, 170–178/175–184 ventral scales in males/females, 62–71/58–63 subcaudal scales in males/females, and 9–11 supralabial scales of which the 3rd is the largest. Toriba and Sawai (1990) give 167–179/172–184 ventral scales in males/females, 56–70/53–63 subcaudal scales in males/females, and 9–10/9–12 supralabial scales in males/females.[4]
