" This species may be distinguished from U. stanshuriana, 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 scutellse 

 imitating the lateral line in fishes. The ground-colour is reddish 

 brown, with trausversely 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 {]{ neai- is .^Baivd) 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 eiglit longitudinal series of enlarged, roundish-hexagonal, 

 strongly keeled dorsal scales, the two median series smaller; the 

 largest of these scales considerably larger than the ventrals ; the 

 rest of the dorsal and lateral surfaces covered with minute smooth 

 granules ; an irregular lateral series of widely sepai'ated enlarged 

 keeled scales. The adprcssed 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, internipted on the 

 vertebral line : lower surfaces whitish, dotted with grey ; belly
