 for study, and from these the following summary of the scutellation 

 has been derived: Ventral plates, 176 to 212; caudals, 31 to 53 

 (males, 41 to 53, average 48; females, 31 to 49, average 45); supra- 

 labials, 7, rarely 8; infralabials, 9, rarely 8 or 10; one preocular; 

 two postoculars, rarely one; temporals usually 2 + 3+4, occasionally 

 one less in any row; posterior chin shields shorter than the anterior or 

 nearly as long, in contact with each other or separated by one or two 

 small scales; loreal distinctly longer than high; scale rows usually 

 21-19, often 21-19-17, on middle of body sometimes 23.
