An investigation was made into the systematics of white-toothed shrews (Crocidura) occurring in Malaya and Indonesia. Most of the forms recorded from this area have been found to represent one of four species: C. fuliginosa (Blyth, 1855), C. attenuata Milne-Edwards, 1872, C. maxi Sody, 1936 or C. monticola Peters, 1870, while the status of a few others remains unresolved at this stage. Each species is discussed and distinguishing features are given in tabular form.
