“This species may be distinguished from U. stansburiana, of 
which it has the general appearance, by a dorsal space covered with 
five or six rows of scales larger than those on the sides of the body. 
Along the middle of the sides there exists one row of small scutelle 
imitating the lateral line in fishes. The ground-colour is reddish 
brown, with transversely elongated black patches all along the upper 
part of the body and tail. The belly is unicolor in the female, 
whilst it is blue in the male.” 
A variety (linearis, Baird) is distinguished in having “ four linear 
interrupted black stripes instead of transverse bands.”

Frontal divided transversely, in contact with the occipital; six 
transversely enlarged supraoculars; two projecting pointed scales 
on the anterior border of the ear. No anterior gular fold. A band 
of six or eight longitudinal series of enlarged, roundish-hexagonal, 
strongly keeled dorsal scales, the two median series smaller; the 
largest of these scales considerably larger than the ventralis; the 
rest of the dorsal and lateral surfaces covered with minute smooth 
granules; an irregular lateral series of widely separated enlarged 
keeled scales. The adpressed hind limb reaches between the 
shoulder and the ear; scales on upper surface of limbs nearly as 
large as the largest dorsals. Ten or eleven femoral pores on each 
side. Tail more than twice as long as head and body ; upper caudal 
scales larger than the largest dorsals; subcaudals sharply keeled. 
Greyish above, with transverse darker spots, interrupted on the 
vertebral line; lower surfaces whitish, dotted with grey; belly 
blue on each side (male).
