the middle of the back. Tail witU a lateral fringe of pointed scales 

 like those of the sides; the pholidosis of the superior surface irregular 

 but without spines. 



The extended hind limb reaches nearly to the posterior border of the 

 orbit. The fifth toe equals or is shorter than the first. Femoral pores 

 8-10, not extended across the belly. Tail tapering, de^jressed through- 

 out, 2.5 times as long as head to base of occipital horns. 



Measurements (Cat. No. 85G7). — Total length, 115 mm. ; length to vent, 

 12 mm.; length to gular fold, IS mm.; length to end of occipital horn, 

 20 mm.; length to base of occipital horn, W mm.; width at temporal 

 horns, 22 mm.; length of fore leg, 30 mm.; length of fore foot, 12 mm.; 

 length of hind leg, 47 mm.; length of hind foot, 19 mm. 



In alcohol this species is graj' above and white below. A blackish 

 spot on each side of the nape, and three pairs of blackish spots about 

 the bases of the large scales on the dorsal region. On each side of 

 these the large scales have a blackish shade at the base, forming a 

 chain like row of s[)ots parallel with the convex lateral outline. Tail 

 with dusky cross lines above. Inferior surfaces immaculate. 



But two specimens of this species are known, and these, in accordance 

 with their desert habitat, are of pallid colors. It is related most nearly to 

 the A. maccallii, and may be distinguished by the absence of the large 

 row of lateral gular scales, the more expanded temporal region, the rela- 

 tively shorter horns, and the generally more slender jiroportions,
