Collections of Aldabran land snails made since 1895 are reviewed to provide a list of species recorded on the atoll. 31 extant species are recorded, of which 5 (16%) are endemic species, 1 (3%) endemic subspecies and 1-2 (3-6%) possibly introduced. 4 of the species believed to be endemic are represented by insufficient material to allow formal taxonomic description. One species, Gulella gwendolinae is suggested to have changed morphology significantly over the last 100 years. Further priorities for land snail research on Aldabra are identified.
