The first species, labeled as A. Dromicus laurentius, is depicted in a long, sinuous form with a smooth texture, featuring a pattern of scales that enhance its streamlined appearance. The second species, identified as B. Dromicus colubrinus, is represented with a more compact body and a unique scale arrangement. Both sections highlight detailed anatomical features, including close-ups of their heads, emphasizing eye structure and scale patterns, alongside a partially shaded background that provides context. This work serves as a scientific reference for distinguishing between the two species, advancing the understanding of their morphology.
