Bangladesh is blessed with 119 species of mammals (Khan 1982). The abundance of such a large number of species in a small territory has been possible because of a diversified flora, a characteristic of tropical forests. However, the existing mammalian population indicates a distinctly
deteriorating trend during the past several decades. No systematic survey of mammals has ever been carried out for the area now under the territories of Bangladesh. It is, therefore, difficult to quantify the magnitude of loss. Our knowledge is limited to some old records made by Blanford (1888) and Pocock 1939, 1941) and some recent works (Choudhury 1969, Mountfort 1969, Husain 1974, Khan 1982). None of these records is complete and uptodate and, therefore, further studies are needed in this direction. A reconnaissance survey was made during 1978 and 1979 to assess the status and distribution of some mammals of Bangladesh. This paper discussess the status and distribution of 21species covering 8 families.
