Of the 243 specimens examined, 237 (97.5%) have the nasal divided below
the naris on both sides. Three specimens have the nasal completely
divided (above and below the naris) on only the left side; one specimen
has a completely divided nasal on only the right side. A groove, but not
a complete division of the nasal, is present above the left naris of one
specimen. One specimen lacks the typical division below the naris on
both sides, but a complete suture is present posterior to the naris and
the resulting postnasal scales are, according to position, loreals.
