抄録

Chromosomes were counted in the preparation of gonad tissues from Cleopatra bulimoides collected from different localities around Qena City in Upper Egypt. The diploid chromosome number of this species was determined to be twenty eight (2n=28). The karyotype was made up of four metacentric, eight submetacentric and two telocentric chromosome pairs. Increased levels of polyploidy in the form of tetraploidy, pentaploidy, hexaploidy, heptaploidy and octaploidy were determined only in the specimens which have dark brown bands on their shells of this species. Shell measurements are also described in details. (These results are reported for the first time in Egypt.)
