Only two species of bird fleas were known from New Mexico: Ceratophyllus celsus celsus Jordan and C. petrochelidoni Wagner, both from the southeastern part of the state. Four new records of the latter species from northcentral New Mexico are added. An unpublished old record and seven new records of C. niger Fox are presented. Records of three rodent fleas, Catallagia decipiens Rothschild, Monopsyllus wagneri (Baker), and M. eumolpi (Rothschild), found in bird nests also are given.
