A comparison of the chromosome complexes of five distinct genera of Marsupials (pouched animals): i, the Opossum with 22 {Didelphys)-, 2, the Koala or Tree Bear with 16 {Phascolarctus) ] 3, the Tasmanian Devil with 14 {Sarcophilus) ; 4, the Common Dasyure with 14 {Dasyurus) ; 5, the Kangaroo with 12 {Macropus).
