sauroctonos

from The Century Dictionary.

• noun The lizard-killer; the name of a bronze statue of Apollo described by Pliny (Nat. Hist. 34–70) which represented the divinity as a boy leaning with one hand upon the trunk of a tree and killing a lizard with an arrow held by the other. This statue is probably represented by many replicas, notably a bronze statuette in the Villa Albani in Rome, and marble statues in the Vatican and the Louvre. The original was probably suggested by some well-known cultus statue.
