patrician and plebeian. On coins the name always occurs with only one l, but in MSS. usually with two. The cognomens of the Atilii under the republic are, BULBUS, CALATINUS, LONGUS, REGULUS, SERRANUS; and of these the Longi were undoubtedly patricians. (Dionys. A. R. 11.61.) The first member of this gens who obtained the consulship was M. Atilius Regulus, ill B. C. 335; and the Fasti contain several consuls of this name under the emperors. The only cognomen found on coins is Saranus, which appears to be the same as Serranus. (Eckhel, v. p. 146.) For those Atilii who have no cognomen, see ATILIUS.

The annexed coin of the Atilia Gens represents on the obverse the head of Pallas winged, and on the reverse the Dioscuri, with the inscription M. ATILI. and underneath ROMA.
