What is "neurotrichus"

Neurotrichus is a genus of shrew-like moles. It is classified, together with the fossil genus Quyania, in the tribe Neurotrichini of the subfamily Talpinae. The only living species is the American shrew-mole (N. gibbsii) of the northwestern United States and British Columbia. A fossil species, ?Neurotrichus columbianus from the Hemphillian of Oregon, was placed in the genus in 1968, but this animal is now thought to be more closely related to the Chinese fossil genus Yanshuella. Another fossil species, Neurotrichus polonicus from the Plio-Pleistocene of Poland, was assigned to Neurotrichus in 1980, and a second Polish Pliocene species, N. minor was added in 1993. Although it was proposed in 2004 to place these two species in Quyania, this has not been universally accepted. Because the name N. minor was preoccupied, it was replaced with Neurotrichus skoczeni in 2010.
