Crispinus occurs as an agnomen in the family of the Penni Capitolini of the Quinctia gens. [CAPITOLINUS, p. 606a.] The full name of the L. Quinctius Crispinus, who was praetor in B. C. 186, and who triumphed in B. C. 184, on account of his victories in Spain, was probably L. Quinctius Pennus Capitolinus Crispinus. (Liv. 39.6, 8, 30, 42.)
