title: Standardized karyotypes for the greater Galagos, Galago crassicaudatus E. Geoffroy, 1812 and G. garnettii (Ogilby, 1838) (Primates: Prosimii).
abstract: Karyotypes were analyzed of 21 greater galagos, using classical, G-banding, C-banding and silver nitrate staining techniques. A composite G-banded karyotype and high resolution idiogram are presented for each species. Areas of possible rearrangement are identified. The results support the interpretations derived from earlier, unbanded studies, rather than a more recent proposal from G-banded data. Failure of repeated attempts to obtain C-bands, despite success in human controls, indicates that the heterochromatic bands generally revealed by these staining methods are either absent or extremely small in greater galagos. Silver staining revealed a single pair of NOR-bearing autosomes in both species, as shown by previous authors.
