Variations. Coloration dark lustrous brown above with a whitish 

 median stripe from snout to rump, beginning definitely in middle of 

 frontal, but usually traceable to f rontonasal (scarcely any variation from 

 young to adult in intensity of this stripe). Median stripe bordered 

 on each side by a band of dark brown as wide as the light stripe. 

 Below light grayish or whitish with olive tinge, darkest on sides of 

 belly; lower jaw with dusky blotches medially; tail blue-gray below, 

 brownish like back above. One adult specimen is uniform dark 

 bronze-brown above, lacking the median light stripe but with the 

 darker bordering stripes fairly indicated. In some specimens the 

 lower parts are brownish without whitish anywhere, the mandible 

 and throat being quite dark and the tail more bluish below.
