Of the 245 specimens examined, 235 (95.9%) have 1 + 1 temporals on each
side. Four specimens exhibit addition of temporals: one specimen has two
secondary temporals on the left, and one has a tertiary temporal on the
left. Two specimens have partly healed head injuries that probably
caused atypical temporal conditions: one specimen has two primary
temporals on the left, and one has two secondary temporals on the left
and two upper and one lower secondary temporal on the right.
Six specimens exhibit reduction of temporals: one lacks a primary
temporal on the left ("temporal" is fused with sixth supralabial), two
lack secondary temporals on the right, and three lack secondary
temporals on the left. The right secondary "temporal" of one specimen is
separated from the supralabials by a posterior extension of the primary
temporal.
Of the 246 specimens examined, 200 (81.3%) have both primary temporals
in contact with their adjacent postoculars. Thirteen specimens (5.3%)
have only the left primary temporal in contact with the postocular and
eight (3.3%) have only the right primary temporal in contact with the
postocular. Twenty-five specimens (10.2%) have both primary temporals
separated from the postoculars. Separation of the primary temporal from
the postocular, whenever it occurs, results from contact of mutual
extensions from the adjacent parietal and supralabial (usually the
fifth).
