Fur sleek; pelage uni-, bi- or tricoloured, colours varying from tan to black. Body slender; snout long, slender, highly movable, with conspicuous vibrissae. Eyes minute but visible; ears usually projecting slightly above pelage. Five upper unicuspid teeth present, with tips coloured brownish to purplish. Females with three or four pairs of mammae.
