Paucituberculata is an order of Metatheria with just one family, Caenolestidae. The members are small, shrew-like animals with small eyes, and thick, grey or greyish-brown pelage. The margin of each upper lip is interrupted by a distinctive flap of skin. The tail is long but not prehensile, and the feet are not syndactylous. Females lack a pouch.
