33. App.ClaudiusPulcher, the brother, possibly of No. 32, was military tribune in B. C. 87. He was appointed to guard the Janiculum when the city was threatened by Marius and Cinna, but opened a gate to Marius, to whom he was under obligations. (Appian, App. BC 1.68.) It appears, however, that he managed to keep his credit with his own party; for it is probably this Claudius who was interrex in 77, and with Q. Lutatius Catulus had to defend Rome against M. Aemilius Lepidus. (Sall. Fragm. lib. 1.)
