Bismite, the momoclinic Bi2O3, was found at small uranium occurrence Rýžoviště near Harrachov, Krkonoše Mts., Czech Republic. Bismite forms grey massive aggregate with greasy luster. Unit cell parameters of bismitea=5.842(6),b=8.170(6, c=7.503(6)A, á=67.09(5)ř for monocline cell and a=5.852(6), b=8.167(5), c=13.820(8) from orthorhombic pseudocell agree good with other publisch data.
