equals the interorbit. The chevron plates, on the outer toes in six, 
on the other toes in nine pairs. No tubercles on the base of tail. 
Grey ; a darker grey stripe runs from the angle of the mouth to the 
shoulder ; above it, a second from the middle of the orbit to and 
along the side of the back ; a third, from the upper part of the orbit 
goes to the nape, and is continuous with its fellow of the opposite 
side. The lateral stripes are joined by backwardly curved trans- 
verse bands, which alone are continued on the tail. All these are 
linear, and in the brightest specimens are edged posteriorly with 
white spots, most evident on the tail, which is thus crossed by pairs 
of short black and white bars. In most examples the spots are 
obsolete, and the lines are broken up into irregular streaks and 
spots. In some the grey ground colour is, by the disappearance of 
the lines, almost interrupted.”
