21 to 26 * gular scales in a straight line between the symphysis of 

 the chin-shields and the median collar-plate, these scales strongly 

 increasing in size towards the collar ; gular fold more or less distinct ; 

 collar even-edged or very slightly serrated, composed of 7 to 10 

 plates. 



Dorsal scales rhombic-hexagonal, more or less distinctly keeled, 

 juxtaposed or subimbricate ; laterals a little smaller, feebly and 

 diagonally keeled or nearly smooth. 37 to 48 scales across the middle 

 of the body t ; 23 (?) to 35 ( J* ) scales, in the middle of the back, 

 corresponding to the length of the head, 2 or 3 on the sides corre- 

 sponding to a ventral plate. Ventral plates in 8 longitudinal series, 

 the second series on each side from the median line much broader than 

 the others, the outer series composed of very narrow plates ; 23 to 25 

 transverse series in males, 27 or 28 in females. J Preanal plate large, 

 with one or two semicircles of smaller plates, one of the median 

 of which is more or less enlarged, and may be desci'ibed as a second 

 preanal. 



Scales on upper surface of tibia smaller than dorsals, strongly keeled. 

 22 to 26 lamellar scales under the fourth toe. 16 to 21 femoral pores 

 on each side.§ 



Upper caudal scales oblique, strongly keeled, with truacate or very 

 obtusely pointed posterior border; the whorls alternately longer and 

 shorter ; 26 to 32 scales in the fourth or fifth whorl behind the post- 

 anal granules. 



Brown above, sometimes more or less greenish above in life,|| with 

 small black spots irregularly disposed ; sides darker, with 4 or 5 series 

 of white, black-edged ocelli, the upper series very regular and extending 

 from the outer edge of the parietal shield to the base of the tail ; 

 a large black spot on each upper labial ; limbs with small ocellar spots. 

 Lower parts bright yellow, or belly bluish green, in life (whitish or 

 bluish in spirit) ; belly sometimes with large black spots, or with small 

 black spots on the sides. Tail with small dark and light spots above, 

 the dark spots sometimes disposed quincuucially.

[I " I saw once or twice green-headed and more or less green-backed lizards 

 run up on the trunks of big cedar trees. I had unfortunately no means of 

 securing them, but I have no doubt that they were Jackson's Lizards" 

 (Lonnberg, I.e. 1911). The variation in colour is therefore exactly as in 

 L. chlorogaster, which may be precisely similar in its markings.
