Numerius, a praenomen among the Romans of rather rare occurrence. M. Varro says that this praenomen was given to those who were born quickly; and that women in childbirth were accustomed to pray to a goddess Numeria, who must have been a deity of some importance, as the pontifex mentioned her in the ancient prayers (Var. Frtgm, p. 319, Bipont.; camp. Hartung, Die Religion der Römer, vol. ii. p. 240). As a Roman praenomen the feminine Numeria could not be used any more than Marca (Varr. L. L. ix. 55, ed. Müller).
