The harmless kind most closely resembling the coral snake probably is
the Mexican milk snake, technically known as _Lampropeltis doliata
annulata_ and found south of Kerrville. The head of this snake normally
is black. Body and tail are marked with a series of from 19 to 25 narrow
yellow rings bordered by slightly wider black rings. The red rings on
the body are just as wide as the combined yellow and two adjacent black
rings. Another of these mimics is the western milk snake (_Lampropeltis
doliata gentilis_), a small species usually less than two feet long,
which is native to central and western Texas. It has a pattern of from
25 to 40 yellow rings which are bordered by black. The red rings are
separated from the yellow by black rings. All rings on this form are
very narrow. In the southeastern part of the state is found still
another of these mimics—the Louisiana milk snake (_Lampropeltis doliata
amaura_). Rarely reaching a length of two feet, this form has a pattern
of narrow yellow rings which are bordered on each side by narrow black
rings. The much wider red rings are separated from the yellow by the
black rings. In the scarlet snake (_Cemophora coccinea_) of eastern and
coastal Texas, the pattern is a series of wide red blotches bordered by
much narrower black bands. The yellow bands, about half the width of the
red ones, are separated from them by the black bands. The belly is
unmarked white or yellow. Adults are about a foot and a half long but a
25-inch specimen is on record.
Size—The coral snake is generally less than two and a half feet long
with a body diameter of about three-eights of an inch. The largest known
specimen is nearly 42 inches long and was collected on the mid-Texas
coast.
Young—This is the only poisonous Texas snake which lays eggs. From two
to nine eggs constitute the egg complement of this form.
