FIGURE 1. Dorsal and lateral views of the skull of H. panamensis (KU 116353) showing various cranial dimensions measured (modified from Trueb, 1974). Abbreviations: HL = head length; HW = head width; IOD = interorbital distance. In our study, "Eye" refers more explicitly to the longitudinal diameter of the bony orbit of the skull. Two measures of the paraoccipital process, not considered by Trueb (1974) also are illustrated.
