Etymology

The subspecific name, sackenii, is in honor of Russian entomologist Carl Robert Romanovich von der Osten-Sacken.[4]

Geographic range

The southern ribbon snake occurs in the southeastern United States in extreme southern South Carolina, southeastern Georgia, and peninsular Florida, at elevations from sea level to 500 feet (152 meters).[5]

T. saurita sackenii is smaller than the other three other subspecies of T. saurita. Adults of T. s. sackenii are 16–30 in (41–76 cm) in total length (including tail). The dorsal color is greenish olive, or blackish in old specimens. It has a dorsal stripe that is vetiver green or light olive-gray bordered on either side with black, and the lateral stripes are marguerite yellow.[6]
