Etymology: Sminthopsis is the name of a genus of tiny carnivorous marsupials from Australia and New Guinea, the best-known being the fat-tailed dunnart. The name was coined by the zoologist Wilhelm Peters, who published it in 1851. It is built from two Greek elements: "sminthos," a mouse, which also appears in the genus name of the mouse-like "Sminthus" dormice, and "opsis," appearance or resemblance, from the same root as "optic." So the name means something like "mouse-like," a description of the animal's small size and overall look. Peters chose a Greek compound because naturalists of the nineteenth century routinely drew on classical languages for scientific names, so the word belongs to that tradition rather than to any ancient vocabulary. The Greek "sminthos" was itself used in antiquity for mice, and in some traditions for the god Apollo Smintheus, a connection that has no bearing on the marsupial, but it shows how old the root is.
