FIGURE 32. Color pattern and color tones of Leptophis praestans: Profile view of the UMMZ 74851 from El Petén, Guatemala. This juvenile specimen retains traces of a postocular stripe (indicated by the arrow) reduced to black margin on eighth and ninth supralabials, occupying lower one-third of anterior temporal and lower one-third of posterior temporal, suggesting a possible ontogenetic change in L. praestans. This condition is absent in adult specimens. Scale bar = 0.5 cm. Photo by N.R. Albuquerque.
