 ciana, uamely, the draiuage basin of the Kio Grande. The locality,

Above light-olive brown; beneath slate color. Longitudinal stripes 

 greenish. Spaces about and between the dark spots on the sides, 

 brick red, these colors belonging to the skin, not to the scales. 



Above dark olive, beneath light-slate color, except the inferior sur- 

 face of the head, which is yellowish white. A broad longitudinal 

 dorsal line of one and two half rows of scales, and an equally distinct 

 one on each side on the second and third dorsal rows, of a greenish 

 slate. The sides of the abdoaien and the exterior dorsal row are dark- 

 slate brown. When the skin is stretched, there are seen on each side, 

 between the dorsal and lateral rows, two rows of quadrate black 

 blotches, the first quite distinct, between the third and sixth rows; the 

 second between the sixth and vertebral line, the spots continent above 

 with each other; the blotches about one scale apart. The intervals 

 between the blotches of a vivid brick red, which color, as well as the 

 black, is sometimes seen on the bases of the adjoining scales, ^oneof 

 the short white lines of IJ. fiirtalis are visible. More or less of white 

 on the inferior surface of the tail. No spots on end of gastrosteges. 



The color wlien living, as described by Say, is dark-brown above, 

 beneath bluish green, head beneath white. A vertebral greenish 

 yellow line, and a lateral pale-yellow one; about eighty concealed red 

 spots or semifascia^ on the skin and lateral margin of the scales.
