Figure 4. Contrast between S. licki (left, MVZ 144,803) and S. hunsakeri (right, MVZ 144,800) in structure of internasal area; actual field length 11.5 mm in each (in median line). In 144,803 three posterior internasals, two primary internasals, latter separated from first canthal on each side by tiny scale posterior to an upper (left) and 2nd (right) postnasal; the four postrostrals irregular; supranasal on each side relatively large, frontoparietals in contact. In 144,800, primary internasals the only internasals present, separated from first canthal on each side by contact of upper postnasal and lateral frontonasal; this symmetry is typical.
