    This paper presents new data on chromosomes of the Palestine mole rat, Nannospalax ehrenbergi, from southeast Anatolia, Turkey. A new chromosomal form, 2n = 56, NF = 62 and NFa = 58, is determined from the region. C-banding revealed pericentromeric constitutive heterochromatin in one submetacentric and seven acrocentric autosome pairs. Two acrocentric autosome pairs and an acrocentric chromosome with a secondary constriction showed interstitial C-positive bands on their long arms. A secondary constriction was detected in the Y chromosome. The NORs were observed in one medium-sized metacentric autosome pair, and in four acrocentric pairs of autosomes.

    Nucleolar organizer region distribution in Nannospalax ehrenbergi (Nehring, 1898) (Rodentia: Spalacidae) from Iraq

    The distribution of nucleolar organizer regions (NORs) in Nannospalax ehrenbergi from Iraq was determined for the first time. In the karyotype of N. ehrenbergi the diploid number, fundamental number, and fundamental autosomal number were 52, 76, and 72, respectively. NORs occur in the telomeric regions of submetacentric and acrocentric autosome pairs.
