This genus of West Indian "shrews", endemic
to the Greater Antilles (except Jamaica) and the Cayman Islands, is represented by as many
as 12 nominal species. These insectivores ranged in size from that of a chipmunk to
a mouse and probably had long flexible snouts. Extinction dates are poorly
constrained, but at least some species survived into the late Holocene and probably
overlapped with the arrival of rats around AD 1500.
