Does phascolarctos cinereus mean koala bear in Greek?

The scientific name for the koala is not "phascolarctos cinereus," it is "Phascolarctos cinereus." It is derived from Greek, where "Phascolarctos" means "pouch bear" and "cinereus" means "ash-grey". However, the common name "koala bear" is a misnomer, as koalas are not actually bears. They are marsupials, and are more closely related to kangaroos and wombats.
