ResumoSalt marsh shrews (Sorex vagrans halicoetes) are common inhabitants of some of the San Francisco Bay salt marshes in California. Their numbers in favorable marshes form perhaps 10 per cent of the mammalian fauna present, the rest of which is chiefly composed of Microtus californicus, Rattus norvegicus, Mus musculus, and Reithrodontomys raviventris, all of which are more abundant than shrews. There is no study yet reported on the biology of salt marsh shrews, and indeed little on the species S. vagrans throughout its range. Comparative material in this paper has been drawn mainly from Clothier (1955), Hamilton (1940), (1944), (1949), Jameson (1955), Blossom (1932), and Dehnel (1952); only the first of these deals with Sorex vagrans. Field work was done from 1949 to 1955, although the major part of this time was spent on studies other than this...
