This completes a search for periodic variable stars within the 30,000 square degrees of the sky covered by the Catalina Surveys. The current analysis covers 81 million sources with declinations between -20 and -75 degrees with median magnitudes in the range 11<V<19.5. We find approximately 34,000 new periodic variable stars in addition to the ∼9,000 RR Lyrae that we previously discovered in SSS data. This brings the total number of periodic variables identified in Catalina data to ∼110,000. The new SSS periodic variable stars mainly consist of eclipsing binaries, RR Lyrae, LPVs, RS CVn stars, δ Scutis and Anomalous Cepheids. By cross-matching these variable stars with those from prior surveys, we find that ∼90% of the sources are new discoveries and recover ∼95% of the known periodic variables in the survey region. For the known sources, we find excellent agreement between our catalogue and prior values of luminosity, period and amplitude. However, we find many variable stars that had previously been misclassified. Examining the distribution of RR Lyrae, we find a population associated with the Large Magellanic Cloud (LMC) that extends more than 20 degrees from its center confirming recent evidence for the existence of a very extended stellar halo in the LMC. By combining SSS photometry with Dark Energy Survey data, we identify additional LMC halo RR Lyrae, thus confirming the significance of the population. Description: In this table we provide the coordinates, magnitudes, periods and variability types of ∼38,000 periodic variable stars detected in Southern Catalina Surveys data. File Summary:

Note (1): As with Drake et al. (2014, Cat. J/ApJS/213/9), the Adaptive Fourier Decomposition (AFD) method (Torrealba et al. 2015, J/MNRAS/446/2251) was run on all candidates to determine the best period for each source. Note (2): Numerical class as follows: 1 = RRab (4325 stars, excludes ∼10500 known SSS RRab's from Torrealba et al. (2015, Cat. J/MNRAS/446/2251) 2 = RRc (3752 stars) 3 = RRd (502 stars) 4 = Blazhko (171 stars) 5 = Ecl (18803 stars) 6 = EA (4509 stars) 7 = ROT (3636 stars) 8 = LPV (1286 stars) 9 = DS (147 stars) 10 = ACEP (153 stars) 11 = Miscellaneous (298 stars) 12 = Cep-II (153 stars) 13 = LMC-Cep (10 stars) Note (3): Flas as follows: I = objects with uncertain period II = objects where there classification varies from Gavrilchenko et al. (2014, Cat. J/MNRAS/441/715)
