The following synoptic revision of the family Cheliferidae is presented at this time in order to render available for routine systematic use the expanded classification of this important family necessitated by recent morphological and systematic research. It follows along the lines already laid down by the author in previous papers on the higher classification of the Chelonethida as a whole (Chamberlin, 1939, 1930 and 1931) and differs only in the fact that consideration of included species is omitted in all but a few special cases.
