Ghana rufous-nosed rat

The Ghana rufous-nosed rat (Oenomys ornatus), also known as the West African Oenomys, is a rodent in the family Muridae. It occurs in Ivory Coast, Ghana, Guinea, Liberia and Sierra Leone. Its natural habitats are subtropical or tropical seasonally wet or flooded lowland grassland and seasonally flooded agricultural land, and it has also been observed in secondary high forest. The Wikipedia article quotes the IUCN Red List as considering it a rare species known only from a few localities in each country where it has been recorded, and describes it as a good climber. The Mammal Diversity Database credits the species to O. Thomas, who described it in 1911 from Bibianaha, near Dunkwa, Ghana, and places it in the tribe Arvicanthini.
