Magellanic Cloud cepheids are of special importance for studies of stellar pulsation, of stellar evolution, of the nature of the Clouds themselves and of the extragalactic distance scale. It is not possible to cover all aspects of this subject in a short review and fortunately this is probably unnecessary since a whole symposium on cepheids is planned for Toronto next year. This paper attempts the much more modest task of assessing the current status on three main topics; chemical abundances, reddenings and the P-L and P-L-C relations (including recent infrared work). Conflicting views on some of these topics have recently appeared in the literature and a survey of the situation seems rather desirable.

AbstractIn the course of the last decade significant advances have been made in the observations of Cepheid variables and in their successful application to the extragalactic distance scale. Much of this progress has come about as a result of new CCD and near-infrared photometry. These recent improvements are discussed, and a comparison is given of Population I Cepheids and Population II distances. The correspondence is good, with the zero points agreeing at a level of better than 15% in distance. At this same level of significance, a systematic difference between these distances scales may exist, in the sense that the RR Lyrae distances appear to be smaller than the Cepheid distances (if it is assumed, as has generally been done for extragalactic studies of RR Lyraes, that Mv(RR) = 0.77 mag, independent of [Fe/H]). However, several recently-published calibrations of Mv(RR) significantly reduce this discrepancy. Finally, new Cepheid data for the nearby galaxy M81 are presented based on recent Hubble Space Telescope observations.
