The mental scale, or mental, in snakes and other scaled reptiles refers to the median plate on the tip of the lower jaw. It is a triangular scale that corresponds to the rostral of the upper jaw. The reference to the term 'mental' comes from the mental nerve which addresses the chin and lower jaw in animals. In snakes, the shape and size of this scale is sometimes one of the characteristics used to differentiate species from one another.

Barbarous the stalking tide;
Her, nor balked nor sated
But plunged into the wide
Area of mental ire,
Lay at her wandering side.”
