Etymology

edit

The specific name, taylori, is in honor of a "W. Taylor". To whom this abbreviation refers is unclear. It may refer to Walter Edgar Taylor, who was an American ornithologist and herpetologist,[3] or it may refer to a William Taylor of the British Museum.[1]

Geographic range

edit

S. taylori is found in southern Texas and in the Mexican state of Tamaulipas.[1]

Reproduction

edit

S. taylori is oviparous.[1] Clutch size is about six eggs. Each egg measures about 20 mm × 6 mm (0.79 in × 0.24 in).[2]
