Abstract:	The chromosomes of the hairy-footed flying squirrel Belomys pearsonii from Taiwan were analyzed with conventional and Ag-NOR staining and G- and C-banding technique. The diploid chromosome number (2n) and fundamental autosomal arm number (FN) were 38 and 72, respectively. The karyotype consisted of six pairs of metacentrics (nos. 1-6), twelve pairs of submetacentrics or subtelocentrics (nos. 7-18), an unusually large-sized metacentric X chromosome, and an acrocentric Y chromosome. The satellite structure, which corresponded to the NOR detected by silver-staining, was observed on the long arm of no. 1 chromosomes. All autosomes and the X chromosome had centromeric constitutive heterochromatin (C-heterochromatin), and the long arms of nos. 17 and 18 chromosomes were entirely heterochromaic. By the C-banding technique, the Y chromosome was entirely stained somewhat darkly than euchromatic region, but did not seem to be genuinely heterochromatic. On the basis of the cytogenetical characteristics of sex chromosomes, the phylogenetic position of Belomys in the group of flying squirrels was briefly referred.
