FIG. 2 in Fossil dipsadid snakes from the Guadeloupe Islands (French West-Indies) and their interactions with past human populations

FIG. 2. — Morphological variability among four specimens of Alsophis Fitzinger, 1843. From left-to-right: smallest and largest available specimens of Alsophis rijgersmaei Cope, 1869 and Alsophis antillensis (Schlegel, 1837) varieties A and B (of Duméril et al. 1854). The two figured vertebrae for each specimen correspond to the most different morphologies observed among the trunk vertebrae (anterior vertebra on the left and median vertebra on the right).
