A catalogue for all 2,770 variable and suspected variable stars marked on the Charts for Southern Variables, Series 1 to 23 is presented. Within this list, 726 are designated as suitable for observation by visual observing methods. One supplementary table provides additional data on selected stars while two other tables give identifications with the official IAU designations allocated since the original charts were published. 1. INTRODUCTION from GCVS4 or NSV is given (if assigned) together with the constellation and the corresponding chart number. This paper provides an index for the 2,770 variable stars shown on the Charts for Southern Variables (Series 1-23). The fourth part of the catalogue (Table 4) lists those stars Series 1-7 were the combined work of F.M. Bateson, A.F. marked on the Charts for Southern Variables (Series 1-23) Jones, I. Stranson, B. Sumner and R. Winnett. Later series that have been assigned a number in the New Catalogue of were the work of F.M. Bateson and M. Morel, with Suspected Variables (NSV). Given the NSV number for a occasional valuable assistance from those responsible for the star, Table 4 gives the chart number and the constellation. If earlier series.

The stars shown on the have GCVS4 names will be found under those names in charts and assigned an NSV number are listed in Table 4 Table 1. together with any assigned GCVS names. In Table 4, an entry under Chart Name indicates that the name of the star on the chart is different from its NSV name. 4.

Any star listed in Table 1 for which there are additional data or explanatory comments is listed in Table 2.
