The chromosome complement of Meriones tristrami Thomas (Rodentia, Gerbillinae), the Israel desert jird, studied by the new technique of chromosome identification (Q and G banding) is described. The diploid number is 72. There are two pairs of submetacentric autosomes (1 and 2) and 33 pairs of acrocentric autosomes. The X chromosome is the largest submetacentric and the Y is the fourth in length among the submetacentric chromosomes of the karyotype. The Fundamental Number (F.N.) is therefore 78 and not 76 as described by Matthey in 1957.
