are without black borders. The dorsal stripe occupies the middle and 

 parts of two adjacent rows of scales on the anterior half of the length, 

 and one row on the posterior half, and is continued to the end of the 

 tail. The lateral stripe covers two entire rows of scales except on the 

 posterior half, where it occupies the second row only. It is bordered 

 belowby a baud of a rather lighter brown than that of the space above it, 

 on the first row of scales, and on the angles of the gastrosteges which 

 enter between the separate scales of the latter. Every other scale of the 

 first row has a black speck at its upper and lower base. Belly immacu- 

 late yellow, except a l)lack shade at the base of the extremity of a few 

 of the scuta, which is only visible on stretching the latter apart. 



This handsome form resembles the Eutcenia clegans brunnea in gen- 

 eral form and appearance, but the latter has no nuchal spots nor black 

 labial borders nor band beneath the lateral stri[)e. It belongs to a

different section of the genus. Its nuchal spots and labial borders are 

 like those of the EaUvnla e. equeti, but it is not a slender-bodied 

 species, and the scales are wider than in that form, representing a dif- 

 ferent type in the genus. 



I have seen but one specimen of this species, which 1 obtained near 

 Lake V^ alley, in southern New Mexico. There is no specimen in the 

 United States National Museum.
