published recommendations for the common names of rodents. They compiled six indigenous names for this species: the

Kuuku Ya'u name ''Thupi''. Despite this they recommended the adoption of the name Mati, which is a general name for rats and mice recorded from the vicinity of the
Peach River on
Cape York.
