“This species may be distinguished from U. stanisburiana, 
of which it has the general appearance, by a dorsal space cov- 
ered 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 scutellae imitating the lateral lines of fishes. 
The ground color is reddish brown, with transversely elongated 
black patches all along the upper part of body and tail. The 
belly is unicolor in the female while it is blue in the male.” 
The range is said to be from Texas to California. It has not 
been encountered by our collectors.
