trils. Scales on belly subhexagonal ; ou the back smaller, rounded, 

 tubercular, and not larger along the middle line. Scales of gular fold 

 as large as those between the fore legs. Femoral pores about 18. 

 Scales on the under surface of the feet hard and smaller; only obso- 

 letely carinated or quite smooth; on the dorsal surface of the tail 

 behind obsoletely keeled; elsewhere smooth. T.ail about twice the 

 body; hind foot about two-fifths the body; no dark collar; general 

 color a brownish yellow, with rather obsolete circular and pretty large 

 blotches distributed pretty uniformly over the back and sides of head 

 and body and exposed surfaces of the legs, the interspaces finely dot- 

 ted with yellowish (on single scales). The tail is ringed alternately 

 with brown and yellowish, the brown rings forming two blotches on each

 more or less confluent obsoletely below. The under parts are yellow-

Sometimes the whitest dots are disposed so as to constitute an indis-

 are generally two dorsal series of these blotches much larger than the 

 others. There are usually more or less faint traces of transverse light 

 bars on the back, especially toward the base of the tail, and sometimes 

 on the flanks; in young specimens distinctly traceablfe as far as the 

 head. 



In younger specimens, the light spotted reticulation is more continu-
