FIGURE 5 in A cryptic new species of Indigo Snake (genus Drymarchon) from the Florida Platform of the United States

FIGURE 5. Differences in infralabial and temporal scale morphology between the A) Eastern Indigo Snake, Drymarchon couperi (Holbrook, 1842), and B) Gulf Coast Indigo Snake, D. kolpobasileus, found in this study. Illustrations originally taken and modified from Cope (1900). Note that D. kolpobasileus has relatively deeper and shorter 7th infralabial scales, shorter temporal scales, and overall shorter and shallower head dimensions (not depicted).
