The infralabials are five, six (usually), or seven on a side (Table 1).
When five infralabials are present on either one or both sides, the
reduction results from one of the following conditions: a) 2 and 3 are
fused (N = 3); b) 1, 2, and 3 form 1 and 2 (N = 6); c) 2, 3, and 4 form
2 and 3 (N = 3); d) 5 is separated from the edge of the lip by a
projection from an adjacent infralabial (N = 1); e) 1, 2, 3, and 4 form
1, 2, and 3 (N = 2); f) type of reduction unknown (N = 4).
Of the specimens with 5-5 infralabials, two have the same type of
reduction on each side, one has a different type of reduction on each
side, and the type of reduction is unknown for the other two specimens.
When seven infralabials are present on either one or both sides, the
addition can result from infralabials 2 and 3 forming 2, 3, and 4 (N =
2); the type of addition is unknown in one specimen.
In one specimen the second infralabial on the right side is reduced to a
small wedge-shaped granule and in another specimen several infralabials
on both sides are irregularly divided horizontally, although both
specimens have six infralabials on the sides having the abnormalities.
