 at the time of Péron's visit, and I believe, if authentic specimens from these localities were in existence we should find that each of these islands had had a distinct species or race of Emus. Taking this for granted, and also taking into account that it is slightly different from the type of D. peronii, I have come to the conclusion that the Liverpool specimen is an immature, though full-grown individual from one of these other islands; but it is not possible from this one rather poor specimen to separate it from the Kangaroo Island species, especially as there is absolutely no indication of the origin of this specimen.

Habitat: Island of Decrès or Kangaroo Island.

One stuffed specimen (Type) and one skeleton in Paris, one skeleton in Florence, and one stuffed specimen in Liverpool (an species diversa?). Also some leg-bones in Adelaide, Australia.

Dr. H. O. Forbes, who kindly lent me the last-named specimen, was the first to point out the differences of this bird from D. novaehollandiae. It is certainly totally distinct from birds of similar age of either D. novaehollandiae or D. n. irroratus.
