Variation of red cell acid phosphatase in two species of kangaroos.

INHERITED variation has been recently demonstrated in the transferrin of an Australian marsupial, Macropus rufus (=Megaleia rufa)1. So far no other variation has been shown in the blood of this or other marsupials. The present communication reports the investigation of red cell acid phosphatase in two species of Australian marsupials, M. rufus and M. giganteus, the former commonly known as the red kangaroo and the latter as the grey kangaroo.
