 back, and tail the ground colour is broken by various variegations partly 

 yellow and partly liver-brown, on the middle of the back and base of the 

 tail these variegations consist of one, two, or more series of small square 

 yellow spots, each either placed upon a liver-brown bar or spot, or edged on 

 both its sides with that colour. On the edges of the back and tail the same 

 colours constitute the variegations, but instead of being in spots or bars they 

 are in narrow longitudinal lines commencing near the outer angle of the eye 

 and terminating beyond the last half of the tail ; these lines are three in

 The sides of the body from the eyes backwards are greyish brown, profusely 

 variegated with spots and irregular vertical stripes of yellow and liver- 

 brown. Outer surface of fore legs light yellowish brown freckled with 

 minute, umber-brown and yellowish white spots; the outer surface of hinder 

 legs purplish brown and freckled with the same colours and in the same
