Full registration data for all identifiable non-fossil primary and secondary type specimens of reptiles and amphibians currently or previously in the Australian Museum are presented, and the current status and registration history of these specimens described, together with any discrepancies between these data and those published in original descriptions. The current identity of the taxa represented by these types is given, together with reference to the original proposer of synonymies and new combinations. Some new synonymies, particularly involving species described by R.W. Wells and C.R. Wellington, are proposed.
