Big Spring Legless Lizard vs. San Diegan Legless Lizard

Their ranges do not meet: springs on the Mojave side of the southern Sierra (Big Spring) vs southern California's coast, valleys and mountains (San Diegan). A: A DOUBLE dark stripe low on each side, unbroken from the head to the tail tip in the Big Spring Legless Lizard; a single dark side stripe (if double, it never runs the whole length) in the San Diegan Legless Lizard. The double side stripe is the only body mark; otherwise range decides. RANGE IS THE SUREST WAY TO TELL THEM APART: where you are decides which one it is; the rows below help confirm it.
